Overview of Enterprise ServerTroubleshooting
This chapter describes the tools, methods, and information sources available for
troubleshooting Sun GlassFish Enterprise Server v3 Prelude. Guidelines for evaluating and
investigating a problem are included.
This chapter contains the following sections:
■
■
■
Identifying the Problem
Application servers are typically deployed in complex and sophisticated operating
environments and involve many technologies, products, and tools. Understanding and
diagnosing problems in a large piece of software with so many components performing so
many tasks can be challenging. This section gets you started, and includes the following topics:
■
■
■
■
First Steps
Sometimes the most obvious solutions are overlooked. As you begin your investigation, try the
following steps first.
13
Identifying the Problem
Verify System Requirements and Configuration
Problems are often caused by configuration issues (system, JVMTM, server, or application-level)
and by resource issues (such as when a system runs out of memory). Refer to the Sun GlassFish
Enterprise Server v3 Prelude Release Notes for the latest information regarding system
requirements dependencies.
Review Known Issues
Your problem might be related to a known issue for the release. Refer to the Sun GlassFish
Enterprise Server v3 Prelude Release Notes for the latest information regarding known issues and
possible workarounds. Also search the GlassFish issue tracker at
Search the Product Documentation
Enterprise Server includes complete documentation. Search the documentation to see if your
problem is addressed. The documentation set is available at
a list of books in the documentation set and a description of their contents.
Search the GlassFish Mailing Lists and Forums
Lists and forums are extremely helpful resources, and are accessed as follows:
■
GlassFish mailing lists (start with users@glassfish.dev.java.net):

Learn More About Enterprise Server v3 Prelude
As the name suggests, the release is a prelude to Sun GlassFish Enterprise Server v3. It is not a
full Java EE 5 application server, and not everything that was implemented in Sun Java System
Application Server 9.1 (GlassFish v2) is implemented and functional in Enterprise Server v3
Prelude. You might be trying to do something that is not possible with the existing feature set.

Sun GlassFish Enterprise Server v3 PreludeTroubleshooting Guide • November 2008
Identifying the Problem
Note – Some resources refer to GlassFish v3 Prelude. GlassFish v3 Prelude is the community
version of the commercially supported offering, Sun GlassFish Enterprise Server v3 Prelude.
The software is the same; the difference is in support.
Search the SunSolve Knowledgebase
SunSolveSM is Sun's informational and patch database service with a browseable directory of all
publicly available Sun Microsystems support documents. SunSolve is available at
http://sunsolve.sun.com. Additional resources are also available for customers with support
contracts.
Gathering Information
Troubleshooting and analysis require information. The more information that you have, the
easier it is to classify a problem and search for its solution. Detailed information will also be
necessary should you need to contact others for support, either through a community mailing
list or through more formal Sun support channels.
For general information about gathering data, also refer to Sun Gathering Debug Data for Sun
Java System Application Server. The document pertains to previous versions but much of the
information is generic enough that it might be helpful for Enterprise Server v3 Prelude.
As you continue your investigation, consider the following questions.
When Does the Problem Occur?
■
What do the logs show? What kind of error message are you getting? For more information
■
What are you trying to do when the problem occurs, and how are you doing it? What is the
sequence of events?
■
Does the problem occur every time you perform the same type of operation, or does it seem
random? Can you reproduce the issue?
■
Have other events or problems occurred that could possibly be related, such as web sessions
closing early, exceptions being thrown in your own application logic, components not being
correctly deployed or undeployed?
What IsYour Environment?
■
What version of Enterprise Server are you using? What operating system and version? What
JDK version?
■
What resources does your system have, such as memory, disk, and swap space? If system
memory is an issue, look for ways to optimize your configuration and consider taking other
actions such as adding memory or decreasing system load.
Chapter 1 • Overview of Enterprise ServerTroubleshooting
15
Identifying the Problem
■
Have any patches been applied? If so, what are the product and operating system patch
numbers?
■
■
What other products and technologies are installed and being used in the installation?

How is Enterprise Server connected to the directory server?
What JDBC driver is being used to access the database?
What IsYour System Configuration?
■
What are your settings?
■
On which port is Enterprise Server v3 Prelude configured? The default or something else?
■
What defaults were changed during installation and what are the values?
■
What other settings were changed from the defaults and what are their values?
■
What are the JVM heap, stack, and garbage collection-related parameters set to?
■
What are the JVM options?
■
What is the permgen size? OutOfMemoryError:PermGen space errors are common and
indicate that you need to increase the permanent generation space available.
■
Is SSL enabled?
■
What are your network settings (proxy, firewall, and so on)? What happens if you disable
your firewall and attempt the task?
What Is Different?
■
What is different that could have provoked the problem or triggered the event? Was
something new added or changed? Have any new applications been deployed? If changes
have been made recently, consider backing them out and seeing what happens — does the
problem still occur?
■
Was the feature or functionality working correctly at one time? If so, what changed or
happened between then and now?
■
Is this working on another system? If so, what is different about that environment?
Examining Log Files
Logging is one of your most important troubleshooting tools. It is the process by which
Enterprise Server captures data about events that occur during server operation. This data is
recorded in a log file, and is usually the first source of information when Enterprise Server
problems occur. The primary purpose of log files is to provide troubleshooting information.
16
Sun GlassFish Enterprise Server v3 PreludeTroubleshooting Guide • November 2008
TroubleshootingTools
By default, all Enterprise Server log information is captured in the server.log file, typically
located in domain-dir/logs. Log Viewer is not available in Enterprise Server v3 Prelude. You
cannot view the server's log file or configure logging using the Administration Console. To view
log information, open the server.log file in a text editor. You can also use command-line file
viewing commands such as tail, grep, or more. Logging is configured by editing the
logging.properties file, located by default in the same directory as the domain.xml file,
typically domain-dir/config.
Log levels such as SEVERE, WARNING, INFO, CONFIG, and others can be set to provide different
types and amounts of information. Each Enterprise Server module has its own logger, and each
logger has its own namespace. Log levels can be set globally for all loggers, or individually for
module-specific loggers.
Server v3 Prelude Release Notes for any known issues related to logging.
Monitoring the System
Monitoring is another helpful tool. It is the process of reviewing the statistics of a system to
improve performance or solve problems. By monitoring the state of various components and
services deployed in Enterprise Server, you can identify performance bottlenecks, predict
failures, perform root cause analysis, and ensure that everything is functioning as expected. For
TroubleshootingTools
Several tools are available that can be used to collect information for troubleshooting purposes.
This section provides basic information about the following:
■
■
■
Operating System Utilities
Operating system utilities, such as pkginfo and showrev on Solaris and rpm on Linux, are
helpful in gathering system information.
The ps -ef command provides helpful information about processes that are running,
including their process identification numbers (PIDs).
Chapter 1 • Overview of Enterprise ServerTroubleshooting

TroubleshootingTools
StackTraces andThread Dumps
A stack trace is a user-friendly snapshot of the threads and monitors in a Virtual Machine for
the Java platform (Java Virtual Machine or JVM machine). A thread dump shows what every
thread in a JVM is doing at a given time and is useful in debugging. When the application server
freezes, hangs, or becomes sluggish for no apparent reason, you should generate and analyze a
thread dump.
This section explains how to obtain a thread dump for Enterprise Server. More information
about analyzing the information contained in a thread dump can be found in “An Introduction
to Java Stack Traces”
default, the server dumps a core file and restarts with the -Xrs java-option flag in the
server.xml file.
▼
To Obtain a ServerThread Dump
●
Type the following command:
asadmin generate-jvm-report --type=thread
VisualVM
VisualVM is a Java troubleshooting tool that uses various technologies such as jvmstat, JMXTM,
and Attach API to access monitored applications. VisualVM is a tool for visualizing data
sources and by default visualizes the following types: applications, hosts, snapshots, core
dumps, heap dumps, and thread dumps. These data sources are visualized in VisualVM so that
they can be monitored for the purposes of analysis, management, and troubleshooting.
VisualVM is commonly used to detect memory leaks.
VisualVM has a GlassFish plugin that enhances monitoring of hosted applications by adding
specialized overview, a tab for monitoring the HTTP Service, and the ability to visually select
and monitor any of the deployed web applications. You can experiment with VisualVM
troubleshooting capabilities, but note that various features depend on the Java versions used in
the client and server. Depending on your configuration, you might only get parts of the
VisualVM features. For more information about VisualVM, see

Did the Server Start?
Description
If the console window is still open, the expected message is:
Domain domain Started
where domain is the name of the default domain. This indicates that the default domain was
started successfully.
If the console window is already closed, check for messages in the log file:
as-install/domains/domain1/logs/server.log
If startup was successful, the expected message is similar to that on the console, and appears at
the end of the log file.
Was the Server Started at the Expected Port?
Description
The server might be running at a different port number than expected, either because it was
intentionally installed there, or because another server was already running on the default port
when the server was installed.
▼
To DetermineWhich Port Number the Server Is Actually Using
1
Examine the server's configuration file:
as-install/domains/domain1/config/domain.xml
2
3
Find the http-listener element.
Inspect the value of the port attribute.
Be sure to enter the correct port number when invoking the server.
Note – The server's default port number is 8080, however, there are a number of ways in which
the expected value can change:
■
A different port number was specified during installation.
A previous installation exists.
■

When attempting to open the start page of Enterprise Server, the initial screen does not appear.
When this error occurs, check the following:
■
■
Is the Server Available Locally?
Description
If the server cannot be accessed from the web, but it is running locally, then the server is actually
running.
Solution
Verify that the server is running locally.
▼
ToVerifyThat the Server Is Running Locally
1
2
Log on to the host where the server is running.
Go to the local web page. For example, if 8080 is the default port, go to:
If the start page does appear, the web connection is encountering a problem that prevents
accessing the server remotely. If the start page does not appear, see “Did the Server Start?” on
Is the Proxy Setting Causing a Problem?
Description
The server should be accessible directly from the host on which it is running (localhost); for
example, using the default port 8080:
Solution
A server instance running on localhost might not be accessible if the server host machine is
connected to the web through a proxy. To solve this problem, do one of the following:
Chapter 2 • Specific Issues
23
Cannot Access the Administration Console
■
Set the browser to bypass the proxy server when accessing localhost. Refer to the browser's
help system for information about how to do this.
■
■
Use the fully-qualified host name or IP address of your system; for example:
Create an entry in the system's hosts file (for example, pointing 127.0.0.1 to localhost;
127.0.0.1 is not proxied).
Note – To find the host name and domain for the localhost machine:
■
On Microsoft Windows — On the desktop, right-click My Computer and select Properties
from the pop-up menu. A System Properties dialog is displayed. Click Network
Identification to see the computer name.
■
On Solaris or Linux — Type hostname at the command prompt.
Cannot Access the Administration Console
The Administration Console provides an interface for administrative functions. If the
Administration Console is not accessible, check the following:
■
■
■
Is the Application Server Running?
Description
The server must be running before the Administration Console can be accessed.
Solution
running.
24
Sun GlassFish Enterprise Server v3 PreludeTroubleshooting Guide • November 2008
Cannot Access a Server Application
Is the Administration Console Running on the
Expected Port?
Description
The default port number for the Administration Console is 4848. However, it could be running
on a different port number than expected, either because it was intentionally installed there, or
because that port was in use when the server was started.
Solution
the port on which the Administration Console is running. Be sure to enter the correct port
number and HTTP protocol when invoking the Administration Console.
Is the Security Manager Disabled?
Description
The Security Manager is not optional; it must be enabled in Enterprise Server. Because there is
no configuration interface in Enterprise Server for disabling the Security Manager, it can only
be disabled when you directly modify the domain.xml configuration file in such a way that the
following line is removed or commented out:
<jvm-option\>-Djava.security.policy=yourPolicy</jvm-option\>
Solution
Verify that the -Djava.security.policy=yourPolicy option is present in the domain.xml file.
Cannot Access a Server Application
If a particular application cannot be accessed through Enterprise Server, check the following:
■
■
■
Is the Application Server Running?
Description
If Enterprise Server is not running, applications are not accessible.
Chapter 2 • Specific Issues
25
Cannot Access a Server Application
Solution
running. The server must be running before a server application can be accessed.
Was Application Deployment Successful?
Description
An application must be successfully deployed before it can be accessed.
Solution
Check the server's log file:
as-install/domains/domain1/server.log
Administrator User Name or Password Not Known
If you have forgotten the administrator user name, you can find it by inspecting the
as-install/domains/domain-name/config/keyfile file, where domain-name is the name of
the domain. In the default domain, domain1, the file to inspect is
as-install/domains/domain1/config/keyfile. For a different domain, substitute its name in
the path.
If you have forgotten the administrator password, you must create a new user name-password
pair by removing the user name and password, creating new ones, and restarting the server.
(You will not be able to read the password, because it is encrypted in the keyfile.)
▼
To Remove the User Name and Password Completely
1
2
Stop the server, if it is currently running.
Change to the appropriate WEB-INF directory; for example:
as-install/lib/install/applications/adminapp/adminapp_war/WEB-INF
3
Comment out the entire <security-constraint> element in the web.xml file.
Do not delete the element, as you will be reenabling it later. This action disables security for
command-line operations.
26
Sun GlassFish Enterprise Server v3 PreludeTroubleshooting Guide • November 2008
ServerWill Not Start onWindows (Port Conflict)
Note – The commands will still expect a value for --username (or -u) and --password (or -w).
But these can be dummy values, since the server side does not impose any security.
4
5
Start the server.
At this point, the server does not have command-line security.
Create a plain text file that defines the AS_ADMIN_USERPASSWORD variable as follows:
AS_ADMIN_USERPASSWORD=adminpassword
adminpassword
Your choice of password for the administration user's password.
6
Create an administration user whose password is the password that you defined in the
preceding step.
asadmin create-file-user --groups asadmin --passwordfile=password-file adminuser
passwordfile
adminuser
The full path to the file that you created in the previous step.
The name of the user that you are creating.
This command adds an entry to the as-install/domains/domain-name/config/keyfile file.
Uncomment the <security-constraint> element in the web.xml file.
Restart the server for the new user name-password to take effect.
7
8
Note – After the server is restarted, remote commands must specify adminuser as the
administration user and adminpassword as the administration password.
ServerWill Not Start onWindows (Port Conflict)
If a message similar to the following is displayed when starting Enterprise Server on Microsoft
Windows, a server port conflict has occurred:
Address already in use
This error occurs when another application is running on the Enterprise Server port (default
8080), or because a previous instance of Enterprise Server did not shut down cleanly.

Is Another Application Running on the Server's Port?
If another application is using the server's port, stop the other application, then restart
Enterprise Server.
Has an Ungraceful Shutdown Occurred on a Previously
Running Server?
Use the asadmin stop-domain command to stop the server, or explicitly kill the Java process
and then restart Enterprise Server.
Two Server Instances Bind to Same Port onWindows
Description
This problem only occurs on Windows 2000/XP systems with Enterprise Server software, and is
due to a known Windows security flaw rather than a problem with Enterprise Server itself.
The problem occurs when two or more instances of Enterprise Server are created using the
same port number for the instanceport option; for example:
asadmin create-domain -adminport 5001 options -instanceport 6001 domain
asadmin create-domain -adminport 5002 options -instanceport 6001 domain
When the two domains are started on a UNIX or Linux system, a port conflict error is thrown
and the second instance fails to start. However, when the two domains are started on Windows
2000/XP, no error is thrown, both server instances start, but only the first instance is accessible
at the specified port. When that first server instance is subsequently shut down, the second
instance then becomes accessible. Moreover, when both instances are running, the Windows
netstat command only reports the first instance.
Solution
Be sure to use unique port numbers for all server instances on Windows systems.

Cannot Produce a JVMThread Dump After Server Crash
Description
If Enterprise Server crashes, the server dumps a core file and, by default, restarts with the -Xrs
flag, which prevents the dump of a JVM thread dump.

Issues Related to Applications
ErrorWhen Deploying EAR
Description
You tried to deploy a traditional EAR type of application in Enterprise Server but received an
error message instead.
Solution
Enterprise Server v3 Prelude does not include a full EJB 3.0 implementation and does not
support traditional EJB modules. Applications can be packaged for deployment in web archive
(WAR) format only. You can download a partial implementation of a few EJB 3.1 features using
Update Tool, but the bulk of EJB 3.0 (ejb-jar and .ear support) is not available . If you need a
full Java EE 5 implementation, Sun Java System Application Server 9.1 (GlassFish v2) is a better
choice for now. Web applications are the only Java EE application type supported by Enterprise
Server v3 Prelude.

Cannot FindSunDeploymentManager
Description
You cannot find SunDeploymentFactory.java.
Solution
Enterprise Server v3 Prelude does not include the JSR-88 API (SunDeploymentManager is the
implementation of the JSR 88 API). The JSR 88 specification provides a complete description of
the APIs required by the Java EE platform to enable development of platform-independent
deployment tools.
Cannot Undeploy or Redeploy ApplicationWith Open
Streams tojar Files (Windows Only)
Description
On Windows systems, after running an application, subsequent attempts to undeploy it or
redeploy it throw exceptions about the server being unable to delete a file or rename a directory.
On Windows systems, an application may use getClass().getResource or
getResourceAsStream methods to locate a resource inside the application, particularly in jar
files that are in the application or accessible to it. If the streams remain open, subsequent
attempts to redeploy or undeploy the application can fail. In addition, the Java runtime by
default caches streams to jar files for performance reasons.
Solution
Be sure to close streams opened by your applications. Also, if an application needs to be
redeployed or undeployed repeatedly, and also needs to obtain a resource from a jar file using
30
Sun GlassFish Enterprise Server v3 PreludeTroubleshooting Guide • November 2008
Issues Related to asadmin
getResource or getResourceAsStream, consider using getClass().getResource, which
returns a URL object, then invoke the url.setUseCaches method to turn off caching for that
jar file, and use url.getInputStream() to obtain the stream.
Although turning off caching for access to the jar file can slow performance, this approach does
allow the application to be undeployed or redeployed. Note also that if the
getClass().getResourceAsStream method is used instead, then the jar file in which the
resource is located is cached (this is the default Java runtime setting) and remains open until the
server is stopped.

asadmin start-domain Command Fails
The command asadmin start-domain fails with one of the following errors:
■
Error: CLI143 There is more than one domain...
Error: Could Not Start Domain
■
Error: CLI143 There is more than one domain...
Description
When issued with no arguments, the command asadmin start-domain fails with the error:
CLI143 There is more than one domain in C:\\Sun\\AppServer\\domains.
Please use operand to specify the domain.
CLI156 Could not start the domain null.
This error occurs when there is more than one domain in the domains directory, none of them
is named domain1, and no domain is specified with the start-domain command.
Solution
Specify the domain when issuing the start-domain command:
asadmin start-domain domain-name
For example:
asadmin start-domain mycustomdomain

Issues Related to asadmin
Error: Could Not Start Domain
Description
This message comes from Sun Java System Application Server 8. The full message looks like
either:
Could not start the domain.
There are no domains.
or
Could not start the domain.
No default domain. Need to enter a domain.
This error occurs when Sun Java System Application Server 8 is installed on the same system,
and its asadmin command (at /usr/sbin) is found on the PATH before the asadmin command
for Sun Java System Application Server 8 at as-install/bin. The situation is especially likely to
occur on Solaris and Linux systems when . is not specified as part of the PATH variable. Without
. in the PATH, the asadmin command in /usr/sbin is found first, even when the current
directory is as-install/bin.
Solution
Make sure as-install/bin is in the PATH ahead of /usr/sbin, or that . is in the PATH ahead of
/usr/sbin if you access asadmin by changing directories to as-install/bin. Alternatively, if you
do change to as-install/bin to run asadmin, be sure to include./ in the command name; for
example:
cd as-install/bin
./asadmin
Cannot Stop Domain Usingasadmin stop-domain
Description
You cannot stop the domain using the asadmin stop-domain command.
Solution
Search the server.log file for error messages related to your inability to stop the domain. To
kill a process when stop-domain is not working, try $JAVA_HOME/bin/jps and look for the
process with ASMain.

Issues Related to Eclipse
Using asadmin set Command Might Produce
Unexpected Results
Description
Unexpected results are returned when setting variables in a command, such as:
asadmin set name={$a-b}
In this case, name is set to b, not {$a-b} because the shell syntax ${a=b} is interpreted as “if the
variable a is unset, substitute the value b, otherwise substitute the value of a.” This is standard
shell behavior. For example, consider the following:
asadmin set default-config.http-service.http-listener.http-listener-1.port=
${http-listener-1-port}
In this case, default-config.http-service.http-listener.http-listener-1.port is set to
listener-1-port, which is invalid.

Eclipse GlassFish Server Adapter – Port ConflictWhen
Starting GlassFish
Description
On Windows, the following error message is displayed when you start Enterprise Server v3
Prelude using the server adapter within Eclipse:
Please stop the server process using the same port as the one used
by the Application Server. A server process is already running on this port
but we cannot determine if it’s a GlassFish
process (lack of info or credentials)
The message does not list which port is blocked by a server process, making it difficult to locate
the blocking process. Obvious candidates such 4848 or 8080 are not blocked, according to TCP
View.

General Installation
Description
You encounter problems when installing.
Solution
The Enterprise Server installation requires JDK 5 or JDK 6, so check your system for that
dependency. Make sure that the JDK 5 or JDK 6 release bin directory is in your PATH so that the
java binary used with Enterprise Server comes from the JDK release rather than a JRE
implementation. For more information about system requirements and dependencies, see the
Sun GlassFish Enterprise Server v3 Prelude Release Notes. For complete installation information

Issues Related to Security
java.security.AccessControlException: Access
Denied Error
Description
The following error occurs from an application client, or appears in the server.log file:
java.security.AccessControlException: access denied
(java.util.PropertyPermission name write...)
There is a permissions issue in the policy files. Either the client.policy file for the application
client or the server.policy file for server side components does not have permission to set the
property.
Solution
Add the permission in client.policy (for the application client), or in server.policy (for
web modules) for the application that needs to set the property. By default, applications only
have “read” permission for properties.
For example, to grant read/write permission for all files in the codebase directory, add or
append the following to client.policy or server.policy:

To use the application client, set the environment variable VMARGS to the following value:
-Djavax.net.ssl.keyStore=${admin.domain.dir}/${admin.domain}/config/keystore.jks
-Djavax.net.ssl.trustStore=${admin.domain.dir}/${admin.domain}/config/cacerts.jks

How Do I Add Containers?
Enterprise Server has a highly modular architecture that enables you to add new types of
containers that handle many application types, not just Java EE. Enterprise Server defines a
service provider interface (SPI), which container developers implement. The Enterprise Server
framework then invokes the container's implementation of the SPI to detect, deploy, and
manage applications of the new type.
Note – Web applications are the only Java EE application type supported by Enterprise Server v3
Prelude.

Rails and JRuby FAQs
Should I Start an Enterprise Server Domain and
Deploy My Application Into It, or Should I Use the
glassfish_rails Gem?
To continue the question: I'm not sure what the second option does, or why I might choose one
over the other.
Response: In a nutshell, a gem is an application runner. It can run your Rails application but
nothing else. If you use the Enterprise Server v3 Prelude installation, start the domain and
deploy. You can deploy several Rails applications (or Java EE applications even) concurrently
with a different context root. This gives you access to different containers such as web and EJB
and also to the Update Tool. Enterprise Server enables you to host not only multiple Rails
applications, but also any other Java EE application.
If I Deploy an Application Using the glassfish_rails
Gem, Can I Still Access the Administration Console?
No, the gem only runs Rails applications with no extensions or extra features. You must have
Enterprise Server v3 Prelude with a web container to access the Administration Console.
Where in a Rails Application Structure Does Enterprise
Server Look for jar Files to Add to the Classpath for
That Application?
To continue the question: WAR files and exploded Java webapp directories have a WEB-INF/lib
directory. Rails applications also have a lib directory, but this is for Ruby libraries. Where in a
Rails application can I put application-specific jar files? Is there such a place, or must I place
them in the domain/lib directory?
Chapter 3 • Frequently Asked Questions
43
Rails and JRuby FAQs
Response: Place them in the domain/lib directory, or in glassfish/lib. If those bundles are
OSGi bundles, you should place them in the glassfish/modules directory. If you want to
package your own set of jar files with the Rails application, instead of copying the jars in the
glassfish/lib or glassfish/modules directory, you might want to use Warbler. The Warbler
gem lets you package your own jars and creates a WAR file from your Rails applications.

Security FAQs
What HappensWhen No Server Side Realm Is
Configured?
When the application is configured (within XML files), but no server side realm is configured,
the application is authenticated in the default realm. No error is thrown that indicates “No such
realm.”
Can I See theTLS/SSL Handshake Information for an
SSL Client?
Yes. Set the Java debugging property on the JVM. To see the handshake information from the
application client, append the following to the VMARGS variable:
-Djavax.net.debug=ssl,handshake
Can I Change the Keystore Password?
Yes. Use the following Java 2 Platform, Standard Edition (J2SETM) properties to change the
keystore password:
-Djavax.net.ssl.keyStorePassword=password
-Djavax.net.ssl.trustStorePassword=password
Note that the keystore password must match the individual key passwords to perform
operations on the keys, so you must change the keystore password with the property mentioned
above, and then change the password to each key to match that password.
