Hey Kabir, Some hopefully more constructive inputs on aopc: 1) It appears that if any jboss-aop.xml is on the classpath defined by the "classpath" element, it gets applied. In the testsuite, I used a broad classpath, and it picks up a file with the same bindings as the file I name in aoppath. This causes aopc to fail; javaassist complains about seeing the same field twice. The workaround is to not specify anything in aoppath. But that's confusing. Seems to me that if aoppath is used, only bindings specified on the files in that path should be applied. 2) When trying to figure the above out, I look at the Reference Guide and then get really confused. classpath/classpathref -- simple enough. src -- isn't really source (i.e. .java) it's class files. It's basically a subset of classpath, right? This isn't spelled out clearly in the docs and the name of the element is confusing. aopclasspath -- Huh??? 3) Also, having "include" as a nested element within src would be more consistent with normal ant usage.
