Enabling Debugging

When you enable debugging, you enable both local and remote debugging. To start the server in debug mode, use the ----debug option as follows:

asadmin start-domain --debug [domain-name]

You can then attach to the server from the Java Debugger (jdb) at its default Java Platform Debugger Architecture (JPDA) port, which is 9009. For example, for UNIX systems:

jdb -attach 9009

For Windows:

jdb -connect com.sun.jdi.SocketAttach:port=9009

For more information about the jdb debugger, see the following links:

GlassFish Server debugging is based on the JPDA. For more information, see JPDA Options.

You can attach to the GlassFish Server using any JPDA compliant debugger, including that of NetBeans, Java Studio Enterprise, JBuilder, Eclipse, and so on.

You can enable debugging even when the GlassFish Server is started without the ----debug option. This is useful if you start the GlassFish Server from the Windows Start Menu, or if you want to make sure that debugging is always turned on.

To Set the Server to Automatically Start Up in Debug Mode

  1. Use the Administration Console. Select the JVM Settings component under the relevant configuration.
  2. Check the Debug Enabled box.
  3. To specify a different port (from 9009, the default) to use when attaching the JVM software to a debugger, specify address= port-number in the Debug Options field.
  4. To add JPDA options, add any desired JPDA debugging options in Debug Options. See JPDA Options.
