Problem summary
**************************************************************** * USERS AFFECTED: Users of JSF with either PH34711 or * * PH36923 applied on IBM WebSphere * * Application Server versions * * 8.5.5.5-8.5.5.21 and 8.0.0.15. * * Users of the jsf-2.0 feature on WebSphere * * Liberty 21.0.0.4 through 22.0.0.2. * * Users of the jsf-2.0 feature on WebSphere * * Liberty with either PH34711 or PH36923 * * applied. * * Note: IBM WebSphere Application Server * * version 9.0 is unaffected by this error. * **************************************************************** * PROBLEM DESCRIPTION: java.lang.ClassNotFoundException: * * org.apache.myfaces.application.viewstat * * e.SecureSerializedViewCollection * * occurs with session persistence * **************************************************************** * RECOMMENDATION: * **************************************************************** Following PH34711 and PH36923 for jsf-2.0, an export was missed, which will cause a ClassNotFoundException if session persistence is enabled. Both database and memory-to-memory persistence are affected. This exception is encountered during session deserialization as the class is looked up. The resulting stack trace will look similar to: Websphere: java.lang.ClassNotFoundException: org.apache.myfaces.application.viewstate.SecureSerializedViewCol lection at java.lang.Class.forNameImpl(Native Method) at java.lang.Class.forName(Class.java:333) at com.ibm.ws.util.WsObjectInputStream.loadClass(WsObjectInputStrea m.java:229) at ... at java.io.ObjectInputStream.readObject(ObjectInputStream.java:517) at com.ibm.ws.session.utils.SessionLoader$1.run(SessionLoader.java: 112) at java.security.AccessController.doPrivileged(AccessController.jav a:738) at com.ibm.ws.session.utils.SessionLoader.loadObject(SessionLoader. java:106) Liberty: SESN0051E: An attempt to deserialize a session object from the backend has resulted in a ClassNotFoundException Exception is:java.lang.ClassNotFoundException: org.apache.myfaces.application.viewstate.SecureSerializedViewCol lection at ... java.base/java.lang.ClassLoader.loadClass(ClassLoader.java:522) at com.ibm.ws.serialization.DeserializationObjectInputStream.loadCl ass(DeserializationObjectInputStream.java:62) at com.ibm.ws.serialization.internal.DeserializationObjectInputStre amImpl.loadClass(DeserializationObjectInputStreamImpl.java:48) at com.ibm.ws.serialization.DeserializationObjectInputStream.resolv eClass(DeserializationObjectInputStream.java:133) at com.ibm.ws.serialization.DeserializationObjectInputStream.resolv eClass(DeserializationObjectInputStream.java:171) ... com.ibm.ws.session.utils.SessionLoader.loadObject(SessionLoader. java:62) at com.ibm.ws.session.store.db.DatabaseHashMap.getValue(DatabaseHas hMap.java:1613) at com.ibm.ws.session.store.db.DatabaseSession.getSingleRowAppData( DatabaseSession.java:168) at com.ibm.ws.session.store.db.DatabaseSession.getSwappableData(Dat abaseSession.java:81)
Problem conclusion
JSF was updated to avoid this ClassNotFoundException. The fix for this APAR is targeted for inclusion in fix packs 8.5.5.22 and Liberty 22.0.0.3. For more information, see 'Recommended Updates for WebSphere Application Server': https://www.ibm.com/support/pages/node/715553
