[jboss-user] [Microcontainer] - Classpath order within a deployer (to support evil hacks)

I'd like to "patch" a dependency of my deployer by providing a replacement class earlier in the classloader than the original .jar.


  | jboss-rails.deployer/
  |   jboss-rails.jar    # includes my patched org.apache.cxf.staxutils.StaxUtils
  |   cxf-commons.jar    # includes the original version

Right now, I think my jboss-rails.jar comes after cxf-commons.jar, as my replacement class is not used.  I'd like to ensure that my jar is first/earlier in the search process.  I could probably "solve" this by naming my patch jar "aaaaa.jar" but that seems a little bit awkward.

Don't focus on CXF vs jbossws.  Being able to "hot patch" classes through classloader search-order control would be awesome, generally speaking.
