RE: [aspectwerkz-user] Custom annotations with jdk5 and ElementTy pe.TYPE?

Yup that worked although I couldn't use the '&&' notation  as it blows up
with the error below.. I ended up using ... 
<pointcut name="withinInvocation" expression="execution(* *..*(..)) AND
within(@org.neo.swarm.interceptor.within.InterceptWithin *)"/> 

Thanks again Alex!

Error........................................

Error on '&&'

The expression 

"execution(* @org.neo.swarm.interceptor.within.InterceptWithin.*(..))"

is indeed invalid since it does not follow the "type dot methodname" style.
Try with:

"execution(* *..*(..)) &&
within(@org.neo.swarm.interceptor.within.InterceptWithin *)"

Note: since the following is not supported (and is rather ugly anyway)
"execution(* (@org.neo.swarm.interceptor.within.InterceptWithin *).*(..))"
