The error messages are different now. Previously the problem seemed to be theAspectManagerService in JBoss was not starting. Can you send me your code and I'll take a quick look? firstname.lastname@example.org
For the standalone stuff, you need to specify the classpaths and path to your jboss-aop.xml file as shown in the documentation.
Since concurrent jar is NOT on your class path it cannot be found... Also, when running with JDK 1.5, you should use the -javaagent switch rather than -Djava.system.class.loader. There are some batch files in the bin directory of the distribution to help with this. If you have not gone through the tutorial already, so so.
Use JBossAOP, not AspectWerkz.
