I am not sure, but it seems you are trying to run the jboss aop ide. This is badly out of date and do not use it. If you want to run your application from Eclipse, start up Eclipse normally, and put all the aop jars on your application's classpath. The set up a run/debug configuration, and modify the VM arguments to use | -javaagent:/path/to/jboss-aop-jdk50.jar -Djboss.aop.path=/path/to/jboss-aop.xml | View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4173249#...
