Classloading conflicts with apache commons classes for app deployed to WAS 6.1

I have an app that uses apache-commons-collections v3.2.1. When I deploy the war file using the WAS 6.1 Integrated Solutions Console I get errors because the commons-collections.jar file in isclite.ear gets loaded before the one that I bundle with my .war file. The problem is that my application requires v3.0.0+ of commons collections. The one in isclite.e开发者_运维问答ar is version 2.1.

So, can I deploy into WAS 6.1 without involving isclite? Can I just drop a war file into a directory somewhere? Is there an option I can select in the process of deploying through the admin interface to skip or remove the isclite.ear dependency?

Thanks.

I had a very similar problem with ColdFusion where a jar in the server was a different version than the one that was needed by my application. I had to call a non-delegating loader (one that doesn't ask the parent to first load the class before loading the requested jar). The loader I used is open source. You can find out about it at
