Specifying Java™ Secure Socket Extensions (JSSE) debug property for V5.0
 Technote (troubleshooting)
 
Problem(Abstract)
Instructions for setting the required system property of "javax.net.debug=true" when you want to debug the JSSE component of WebSphere® Application Server V5.0.
 
Resolving the problem
The debugging property javax.net.debug=true must be specified as a system property. The InfoCenter instructions are provided below, with additional clarification.

-------------------------------------------------------

By configuring through the javax.net.debug system property, JSSE provides the following dynamic debug tracing: -Djavax.net.debug=true.

A value of true turns on the trace facility, provided the debug version of JSSE is installed. Use the administrative console to set the system property for debugging the application server, deployment manager, or nodeagent.

Application Server:

In the administrative console, go to Application Servers > server_name > Process Definition > Java Virtual Machine > Custom Properties. The name to specify is javax.net.debug and the value is true. The output will be in the file specified in the System.out file name in Application Servers > server_name > Logging and Tracing > JVM Logs, which by default is the SystemOut.log file.

Nodeagent:

In the administrative console, go to Node Agents> node agent name > Process Definition > Java Virtual Machine > Custom Properties.

Deployment Manager:

In the administrative console, go to Deployment Manager > Process Definitions > Java Virtual Machine > Custom Properties.

To collect a trace, follow these steps:

  1. Stop the server to be traced (application server, node agent, or deployment manager)
  2. Move the default version of JSSE (ibmjsse.jar ) into a separate directory that is not in the WebSphere classpath). The default version is located in <install_root>/java/jre/lib/ext directory.
  3. Place the ibmjsse-debug.jar file in the <install_root>/java/jre/lib/ext directory.
  4. Specify the javax.net.debug system property, as indicated in the paragraphs above.
  5. Restart the deployment manager, application server or node agent that is being traced.

The trace is logged by default to the SystemOut.log file, unless you have modified the Java™ Virtual Machine (JVM) Logs settings.
