Sun Java System Web Server 7.0 Update 1 Administrator's Guide

ProcedureEnable JVM Debugging

  1. Select the Configuration.

    Select the configuration from the configuration list. Click Configurations tab to get the list of available configuration.

  2. Click Java > JVM Settings tab.

  3. Select Enable Debug checkbox under Debug Java Settings.

  4. Provide JVM options as necessary by clicking the New button.

    The default JPDA options are as follows:

    -Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=7896

    If you substitute suspend=y, the JVM starts in suspended mode and stays suspended until a debugger attaches to it. This is helpful if you want to start debugging as soon as the JVM starts. To specify the port to use when attaching the JVM to a debugger, specify address=port_number. Check out the JPDA documentation for a list of debugging options.
