[jboss-user] [EJB/JBoss] - ClassLoading problems, JBoss ClassLoading Strategy might be

If ur EJB extends some class such as Spring AbstractXXXEJB, and this very AbstractXXXEJB happens stored in the WEB-INF/LIB DIR of a war file.When try to deploy ur EJB, u'll get a "EJB spec violation... Section 22.2"problem(try search it on google).The reason is that JBoss couldn't find the father class for ur EJB! that means jars stored in WEB-INF/LIB DIR can only be shared in the war project, not on the outside.

Trying to fix this problem, I modified following file: server/default/deploy/jbossweb-tomcat55.sar/META-INF/jboss-service.xml    and active the following propety but that didn't work. Does anybody meet this problem and know how to config the JBoss classloading strategies?
      <!-- A flag indicating if the JBoss Loader should be used. This loader
  |            uses a unified class loader as the class loader rather than the tomcat
  |            specific class loader.
  |            The default is false to ensure that wars have isolated class loading
  |            for duplicate jars and jsp files.
