The JP model offered by AW is very powerfull and I am sure you will find out the means to achieve
your goal.
Please try to read our documentation (http://aspectwerkz.codehaus.org/implementation.html,
http://aspectwerkz.codehaus.org/definition_issues.html,
http://aspectwerkz.codehaus.org/attribute_definition.html,
http://aspectwerkz.codehaus.org/xml_definition.html ;-) ).
You will also find a very good help in the published AOP books.
