what we did with our deployment was to have the class loading setup to load on a per module basis. we have two struts2 portlet deployed with liferay5.1 on WAS. we had a modules first and parent last setting for class loading.
you should check on your EAR deployment descriptor how class loading was setup for your .ear application.
