Re: IOException while loading persisted sessions: java.io.WriteAbortedException

[Mariusz Wojcik]

Hi Thank's Rob, but I don't put  objects  into session directly. This must be done by the engine but I don't know in which moment. The same Exception I get during stopping Tomcat (with portal engine of course). What's going on ? Why this Exception isn't throwing in sample Portal Engine? What I'm doing wrong (maybe I have made the mistake in sitemap configuration)?    Please for help. Best regards mario.    INFO: Removing web application at context path /portal - Cannot serialize session attribute portal-history for session FC0ED92798A123D2BB52AEFFE70486A0 java.io.NotSerializableException: org.apache.cocoon.portal.acting.helpers.LayoutEventDescription  at java.io.ObjectOutputStream.writeObject0(ObjectOutputStream.java:1054)  at java.io.ObjectOutputStream.writeObject(ObjectOutputStream.java:278)  at java.util.ArrayList.writeObject(ArrayList.java:530)  at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)  at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39)  at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25)  at java.lang.reflect.Method.invoke(Method.java:324)  at java.io.ObjectStreamClass.invokeWriteObject(ObjectStreamClass.java:795)  at java.io.ObjectOutputStream.writeSerialData(ObjectOutputStream.java:1294)  at java.io.ObjectOutputStream.writeOrdinaryObject(ObjectOutputStream.java:1245)  at java.io.ObjectOutputStream.writeObject0(ObjectOutputStream.java:1052)  at java.io.ObjectOutputStream.writeObject(ObjectOutputStream.java:278)  at java.util.ArrayList.writeObject(ArrayList.java:530)  at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)  at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39)  at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25)  at java.lang.reflect.Method.invoke(Method.java:324)  at java.io.ObjectStreamClass.invokeWriteObject(ObjectStreamClass.java:795)  at java.io.ObjectOutputStream.writeSerialData(ObjectOutputStream.java:1294)  at java.io.ObjectOutputStream.writeOrdinaryObject(ObjectOutputStream.java:1245)  at java.io.ObjectOutputStream.writeObject0(ObjectOutputStream.java:1052)  at java.io.ObjectOutputStream.writeObject(ObjectOutputStream.java:278)  at org.apache.catalina.session.StandardSession.writeObject(StandardSession.java:1446)  at org.apache.catalina.session.StandardSession.writeObjectData(StandardSession.java:937)  at org.apache.catalina.session.StandardManager.doUnload(StandardManager.java:586)  at org.apache.catalina.session.StandardManager.unload(StandardManager.java:532)  at org.apache.catalina.session.StandardManager.stop(StandardManager.java:734)  at org.apache.catalina.core.StandardContext.stop(StandardContext.java:4436)  at org.apache.catalina.core.ContainerBase.removeChild(ContainerBase.java:995)  at org.apache.catalina.core.StandardHostDeployer.remove(StandardHostDeployer.java:606)  at org.apache.catalina.core.StandardHost.remove(StandardHost.java:955)  at org.apache.catalina.startup.HostConfig.undeployApps(HostConfig.java:1053)  at org.apache.catalina.startup.HostConfig.stop(HostConfig.java:1030)  at org.apache.catalina.startup.HostConfig.lifecycleEvent(HostConfig.java:396)  at org.apache.catalina.util.LifecycleSupport.fireLifecycleEvent(LifecycleSupport.java:166)  at org.apache.catalina.core.ContainerBase.stop(ContainerBase.java:1166)  at org.apache.catalina.core.ContainerBase.stop(ContainerBase.java:1178)  at org.apache.catalina.core.StandardEngine.stop(StandardEngine.java:526)  at org.apache.catalina.core.StandardService.stop(StandardService.java:581)  at org.apache.catalina.core.StandardServer.stop(StandardServer.java:2379)  at org.apache.catalina.startup.Catalina.stop(Catalina.java:643)  at org.apache.catalina.startup.Catalina.start(Catalina.java:618)  at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)  at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39)  at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25)  at java.lang.reflect.Method.invoke(Method.java:324)  at org.apache.catalina.startup.Bootstrap.start(Bootstrap.java:297)  at org.apache.catalina.startup.Bootstrap.main(Bootstrap.java:398)
