I currently have a web application written by a vendor that runs in JBoss 3.2.3, because of some needed functionality we are moving the application to 3.2.6. When we do this it seems that there is a classpath issue. The Tomcat 5.0 which comes with JBoss uses version 0.9.4.3 of Castor and the web application uses version 0.9.5.2. Since we are getting a MethodNotFoundException, it appears to be a classpath issue. In 3.2.3 the snmp-adaptor.sar resides in all the server/* paths, but in 3.2.6 it only resides in the server/all path. Is there anyway to specifiy the classpath used by JBoss when deploying a war?
