Java Remote Debugging

How to attach to a remote process using Netbeans. Add the following to the command line switches for launching the application:

-Xdebug -Xrunjdwp:transport=dt_socket,server=y,address=18889,suspend=y



So if your command line is...

java -Xmx1024m -jar MyFile.jar

Do this...

java -Xdebug -Xrunjdwp:transport=dt_socket,server=y,address=18889,suspend=y  -Xmx1024m -jar MyFile.jar

This will suspend the process, listening on port 18889 until your debugger attaches...

Do this...

java -Xdebug -Xrunjdwp:transport=dt_socket,server=y,address=18889,suspend=n  -Xmx1024m -jar MyFile.jar

...and your process will launch normally but allow you to connect at any time on port 18889.
