Hi, I am working with JBOSS 4.2.3.GA. I have deployed OpenSSO and Policy agent in different server instances. They deployed successfully. When i am trying to access my sample application, I am getting the below exception. java.lang.ClassNotFoundException: No ClassLoaders found for: com.iplanet.services.comm.client.AlreadyRegisteredException org.jboss.mx.loading.LoadMgr3.beginLoadTask(LoadMgr3.java:212) org.jboss.mx.loading.RepositoryClassLoader.loadClassImpl(RepositoryClassLoader.java:521) org.jboss.mx.loading.RepositoryClassLoader.loadClass(RepositoryClassLoader.java:415) java.lang.ClassLoader.loadClass(ClassLoader.java:252) java.lang.ClassLoader.loadClassInternal(ClassLoader.java:320) com.sun.identity.agents.arch.Manager.<clinit>(Manager.java:643) com.sun.identity.agents.filter.AmAgentBaseFilter.initializeFilter(AmAgentBaseFilter.java:267) com.sun.identity.agents.filter.AmAgentBaseFilter.getAmFilterInstance(AmAgentBaseFilter.java:357) com.sun.identity.agents.filter.AmAgentBaseFilter.doFilter(AmAgentBaseFilter.java:69) org.jboss.web.tomcat.filters.ReplyHeaderFilter.doFilter(ReplyHeaderFilter.java:96) Please help me to fix the issue.
