A problem with Aspectwerkz and Tomcat's Classloaders

Maybe I'm doing something wrong, but it seems that running Aspectwerkz 0.9 with Tomcat 5.0.18 (on Sun's JDK 1.4.2_03) , Aspectwerkz works only for classes loaded by "org.apache.catalina.loader.WebappClassLoader" (for example a servlet or an object created in the doGet of a servlet) and does't work for classes loaded by "org.apache.catalina.loader.StandardClassLoader" (for example http request, http response, servlet context, ....).

Does it make sense for anybody ? Is it possible that a different classloader inhibits the ability of Aspectwerkz to intercept calls ?

Any help would be really apreciated.

Thanks in advance.

Maurizio.
