| I'm not sure ;) However, the "linkage error" suggests to me that the JoinPointStaticPart is expecting one or more classes to have a different structure than they do in the test environment. However, I don't know the internals of these things well enough to be certain. Someone from the AJ team may have better insight.
I assume you are using load-time weaving (LTW), since you appear to be advising JSPs. In this case, AspectJ is using a class loader to weave in the advice as the class files are loaded. This is implied by the error message.
I just googled "websphere jdk" and it looks like WAS 5 uses JDK 1.4 while WAS 6 adds support for JDK 1.5. Could you be using different JDK's or at least different VMs (even if you're using the same version compiler)? LTW works differently on 1.4 vs. 1.5. I'm not an expert on the details, but the online documentation for AspectJ should point you in the right direction, if this is really the problem.
Anyway, try Ramnivas' suggestion first!

Are you sure that this issue is specially important if I use aspects? Because building *.war files locally without aop-support (on WAS 5 with Portal 5.1 as i mentioned before) and deploying them to the test env (WAS 6 and Portal 5.1) is no problem at all and works just fine for a longer period of time. Furthermore a colleague just told me that there were some problems setting up the local environment to match the test, that could not be resolved easily...
Thanks for your reply anyway!
