RE: [aspectj-users] keeping aop.xml in system class path and aspect clas

["Ron Bodkin" <rbodkin@xxxxxxxxxxxxxx>]

This is as expected: if you include an aspect in an aop.xml file, the class
file for it needs to be visible to the class loader that included the file.
You could put the aop.xml file in the jar file that is included in your ear
to avoid this problem. You could also include a top-level aop.xml file that
controls system-wide weaving properties but doesn't list the aspects, and
just include a listing of aspects (e.g., from the -outxml compiler option)
in the child loader.

Subject: [aspectj-users] keeping aop.xml in system class path and aspect
classes in a child class loader for LTW?


Hi All, 
I have my aop.xml in system classpath for LTW, so it is getting loaded by
SystemClassLoader But my aspectj classes are bundled in a jar file which is
in my applications's ear file. So these classes are getting loaded by
EARClassLoader (child of System CL). The problem is that when I start my app
server, javaagent is able to find this aop.xml file, but it prints following
exceptions(copying a small piece of exceptions below). Looks like the weaver
can't find aspect classes. Is it because aop.xml is in system class loader
and my aspect classes (those generated from .aj files) are in a EAR class
loader (which is child of system CL)? I purposefully want to keep aop.xml in
system class path; is there any way out? 

Thanks in advance, 
Sandesh
