[ https://issues.jboss.org/browse/JBCLUSTER-315?page=com.atlassian.jira.plu... ] log an updated JBCLUSTER-315: ----------------------------- Description: I have JSF based web application deployed in Jboss 5.1 EAP server. Enabled the distributable tag for session replication across two jboss nodes with Apache web server for failover feature and my business requires Attribute level replication but the system throws NullPointerException. "Failed to replicate session java.lang.NullPointerException" Here is how did I configure jboss for session replication: jboss-web.xml: <replication-granularity>ATTRIBUTE</replication-granularity> web.xml: <distributable/> Expected: Session should be replicated without NPE. Actual: Failed to replicate session 9jYCBgKn2mIIVS2g8EzEzQ__.XXXX Failed to replicate session 9jYCBgKn2mIIVS2g8EzEzQ__.XXXX java.lang.NullPointerException at org.jboss.web.tomcat.service.session.distributedcache.impl.jbc.AbstractJBossCacheService.getMarshalledValue(AbstractJBossCacheService.java:679) at org.jboss.web.tomcat.service.session.distributedcache.impl.jbc.AttributeBasedJBossCacheService.storeSessionAttributes(AttributeBasedJBossCacheService.java:185) at org.jboss.web.tomcat.service.session.distributedcache.impl.jbc.AttributeBasedJBossCacheService.storeSessionAttributes(AttributeBasedJBossCacheService.java:40) at org.jboss.web.tomcat.service.session.distributedcache.impl.jbc.AbstractJBossCacheService.storeSessionData(AbstractJBossCacheService.java:402) at org.jboss.web.tomcat.service.session.ClusteredSession.processSessionReplication(ClusteredSession.java:1192) at org.jboss.web.tomcat.service.session.JBossCacheManager.processSessionRepl(JBossCacheManager.java:2221) at org.jboss.web.tomcat.service.session.JBossCacheManager.storeSession(JBossCacheManager.java:321) at org.jboss.web.tomcat.service.session.InstantSnapshotManager.snapshot(InstantSnapshotManager.java:51) at org.jboss.web.tomcat.service.session.ClusteredSessionValve.handleRequest(ClusteredSessionValve.java:147) at org.jboss.web.tomcat.service.session.ClusteredSessionValve.invoke(ClusteredSessionValve.java:94) at org.jboss.web.tomcat.service.session.JvmRouteValve.invoke(JvmRouteValve.java:88) at org.jboss.web.tomcat.service.session.LockingValve.invoke(LockingValve.java:62) at org.apache.catalina.authenticator.AuthenticatorBase.invoke(AuthenticatorBase.java:433) at org.jboss.web.tomcat.security.JaccContextValve.invoke(JaccContextValve.java:95) at org.jboss.web.tomcat.security.SecurityContextEstablishmentValve.process(SecurityContextEstablishmentValve.java:126) at org.jboss.web.tomcat.security.SecurityContextEstablishmentValve.invoke(SecurityContextEstablishmentValve.java:70) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:127) at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:102) at org.jboss.web.tomcat.service.jca.CachedConnectionValve.invoke(CachedConnectionValve.java:158) at org.apache.catalina.valves.AccessLogValve.invoke(AccessLogValve.java:567) at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:109) at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:330) at org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:829) at org.apache.coyote.http11.Http11Protocol$Http11ConnectionHandler.process(Http11Protocol.java:598) at org.apache.tomcat.util.net.JIoEndpoint$Worker.run(JIoEndpoint.java:451) at java.lang.Thread.run(Thread.java:682) *Debugging details:* I have debugged the application and found that one of the attribute value is null.
