Hi, There is a space before the name of the aspect. This space could be messing with your JBoss AOP... try removing it. Plus, remember that you must specify the complete names of everything in the XML. So, is your SQLDeadlockExceptionInjector aspect in the default package? If not, you must specify the name of the package it is in. Let me know if this fix your problem. View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4209898#...
