Right before the release of JBoss 1.4.1, we've found/fixed a few issues regarding Security (or sandbox) on AOP and Remoting. As discussed on this URL: http://www.jboss.com/index.html?module=bb&op=viewtopic&t=145765&a... (Page 5) I suggest you use the versions available at JBoss5. http://anonsvn.jboss.org/repos/jbossas/tags/JBoss_5_0_0_GA/component-matr... JBossAOP had a few issues also, and they fixed it on JBossAOP 2.0.0.SP1 (I think.. double check on the pom above) You could find the versions you need at http://repository.jboss.com. You would be better on using Jboss5 I guess. Is that an option for you? View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4197240#...
