[Proxool-developer] RE: Proxool 0.8.0RC1 additional dependency

[Switching to dev-list]


Hi Mark. 

This might be jar-mageddon. Did you include the CGLIB jar in Proxool as well as in Hibernate, or are they in the same webapp?

If you have two CGLIB jars could you try to remove them both, and then add one to the Websphere root classloader? I've never used Websphere but I guess it has a global 'lib' directory or somehting?

Another thing you might try is to use this alternative build of CGLIB:
http://prdownloads.sourceforge.net/cglib/cglib-bcel-1.0.jar?download

It uses BCEL as a backend instead of ASM.

Bill:
If this is jar-mageddon we might consider cannibalizing the code into Proxool like we have done with Commons Logging. By the way: Are there any IBM jdks in the SourceForge test cluster?
