Re: [aspectwerkz-user] NoClassDefFoundError on applicatoin init

Hi

Can you confirm that you are using 2.0 ?
This is rather surprising if we look at line 369 in
http://cvs.aspectwerkz.codehaus.org/viewrep/aspectwerkz/aspectwerkz4/src/main/org/codehaus/aspectwerkz/definition/SystemDefinitionContainer.java?r=1.12
since AspectWerkzPreProcessor is packed in aspectwerkz-2.0.jar just as
the other AW classes that appear in your stacktrace.

AW is triggered there since it happens you have a join point in the
class "se.exder.servlet.BundleServlet". The AW jars must be along this
class (ie in the app server classpath if this class belongs there).

-Daspectwerkz.transform.verbose=true may help you perhaps.
