[Jonah]

Many thanks for your reply. I think I do not describe my question clear befor. I want to modify some code in JBoss AS, so I want to set a breakpoint in some code of Jboss AS classes to see its process.  I filled the required argument in Eclipse debug configuration for  org.jboss.Main. However, it cannot be started and print following messages. I tried in commondline, it's ok. Can you give me some advices?  Many thanks in advance.
