I'm working on an JBoss 6.1 environment, which the default options doesn't enable the debug, and everybody sometimes forget to add that option on the deploy. I was wondering if there is a way to enable the debug in an already deployed JBoss... That would be very helpful, depending on the project, restarting the application can last 3 hours! Also, I am using Seam 3.0 (I don't know if that could help in some way).
This seems to be the answer: Debug a java application without starting the JVM with debug arguments.
There aren't any JBoss-specific solutions.
