when I redeploy my application, and when I execute a method, I have this exception:
09:13:07,030 ERROR [[action]] Servlet.service() for servlet action threw exception java.lang.LinkageError: loader constraints violated when linking org/aspectj/lang/reflect/SourceLocation class
The problem is solved.
Actually I had several jars that were contain the same class. I removed the useless and now it's ok.
