JPDA Options

The default JPDA options in Enterprise Server are as follows:

-Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=9009

For Windows, you can change dt_socket to dt_shmem.

If you substitute suspend=y, the JVM software 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 software starts.

To specify a different port (from 9009, the default) to use when attaching the JVM software to a debugger, specify address=port-number.

You can include additional options. A list of JPDA debugging options is available at http://java.sun.com/products/jpda/doc/conninv.html#Invocation.
