But looking at some of your posts here, you seem to be having a hard time trying to debug these javassist runtime issues. Sometime back, there was thread in this forum where a user pointed to a open source library which he had developed as an wrapper to Javassist http://www.fuin.org/srcgen4javassist/index.html . In one of his examples http://www.fuin.org/srcgen4javassist/examples.html he shows how it can be used to generate this debug information from javassist. I haven't personally given it a try, but maybe you might find it useful. You could use that library to wrap to javassist code and print out debug information - thay way you can see the exact code that has been generated. -------------------------------------------------------------- To reply to this message visit the message page: http://community.jboss.org/message/527799#527799
