Question on ClassLoaders

I want to on how websphere app. server will handle this issue
If I have two projects A & B deployed as two different war files a.war and b.war files to the same app. server.
a.war file has lib/hibernate/hibernate3.jar
b.war file has lib/hibernate/hibernate2.jar

both the projects use hibernate api. My question is does app. server load both the jar files and execute each jar against each project? or does it load only one jar file and both project uses the same jar file??

Thanks in advance

Just so you know, with a standard classloader configuration, each war file will use its own set of jar files, so one will use h2, the other will use h3.

Here's a tutorial on Understanding WebSphere Classloaders for more information
