[JBoss-user] Classloader for jboss-3.2.2 with embedded Tomcat-4.1.x

[Brad Balmer]

We are deploying multiple WAR files that share a common base JAR file.  
This common JAR file is located in the individual /WEB-INF/lib of the 
WAR files and will be different from WAR to WAR.  (Needed to do this for 
versioning and not wanting to regression test each application with a 
change to the JAR).

Our problem seems to be with how JBoss/Tomcat is loading the classes.  
The first WAR to be loaded has the oldest version of the JAR inside it.  
When the last application gets loaded (which unfortunately has the 
newest version of the JAR) and subsequently run, I am getting a 
NoSuchMethodError on a class in the JAR, when I know that it is there.

Is there a way to configure JBoss/Tomcat to load each WAR separately so 
that I can have multiple instances of the JAR across several WAR's?

Thank you for any help anyone can give.
