java.lang.NoClassDefFoundError: org/aopalliance/intercept/MethodInterceptor

Trying to run a RESTful webservice using Glassfish and NetBeans6.9.1 I keep getting this exception...It seems to be related to aopalliancce.jar? NB does not include it I downloaded and added it...no joy.

Does anybody have any idea how to get rid of this thing?

You are using Spring which requires the aopalliance library. Download it from here and include in your classpath: http://uk.maven.org/maven2/aopalliance/aopalliance/1.0. You can also grab it using maven from the same place.
