Tomcat 6 clustering problem
Hi all, I've got wicket 1.4-m2 based application running on two different network hosts configured as Tomcat 6 Simple TCP cluster. I try to simulate failover with session replication using the following schema: 1) Log into the first server, store some info in HTTP session 2) Access mounted page on the first server, i.e. http://first.server/mounted/page 3) Try to access the same page on the second server, i.e. http://second.server/mounted/page I assume that HTTP session should replicate between Tomcat's and I want to get immediate reply from the second server, but all I get is forwarding me to the login screen and the following entries in log: Jun 25, 2008 5:10:39 PM org.apache.catalina.ha.session.DeltaManager messageReceived SEVERE: Manager [localhost#/mas]: Unable to receive message through TCP channel java.lang.IllegalArgumentException: Unknown object type null at org.apache.wicket.protocol.http.pagestore.DiskPageStore.restoreAfterSerialization(DiskPageStore.java:1211) at org.apache.wicket.protocol.http.SecondLevelCacheSessionStore$SecondLevelCachePageMap.readObject(SecondLevelCacheSessionStore.java:403) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at java.io.ObjectStreamClass.invokeReadObject(ObjectStreamClass.java:974) at java.io.ObjectInputStream.readSerialData(ObjectInputStream.java:1849) at java.io.ObjectInputStream.readOrdinaryObject(ObjectInputStream.java:1753) at java.io.ObjectInputStream.readObject0(ObjectInputStream.java:1329) at java.io.ObjectInputStream.readObject(ObjectInputStream.java:351) at org.apache.catalina.ha.session.DeltaRequest$AttributeInfo.readExternal(DeltaRequest.java:361) at org.apache.catalina.ha.session.DeltaRequest.readExternal(DeltaRequest.java:255) at org.apache.catalina.ha.session.DeltaManager.deserializeDeltaRequest(DeltaManager.java:619) at org.apache.catalina.ha.session.DeltaManager.handleSESSION_DELTA(DeltaManager.java:1363) at org.apache.catalina.ha.session.DeltaManager.messageReceived(DeltaManager.java:1320) at org.apache.catalina.ha.session.DeltaManager.messageDataReceived(DeltaManager.java:1083) at org.apache.catalina.ha.session.ClusterSessionListener.messageReceived(ClusterSessionListener.java:87) at org.apache.catalina.ha.tcp.SimpleTcpCluster.messageReceived(SimpleTcpCluster.java:899) at org.apache.catalina.ha.tcp.SimpleTcpCluster.messageReceived(SimpleTcpCluster.java:880) at org.apache.catalina.tribes.group.GroupChannel.messageReceived(GroupChannel.java:269) at org.apache.catalina.tribes.group.ChannelInterceptorBase.messageReceived(ChannelInterceptorBase.java:79) at org.apache.catalina.tribes.group.interceptors.TcpFailureDetector.messageReceived(TcpFailureDetector.java:110) at org.apache.catalina.tribes.group.ChannelInterceptorBase.messageReceived(ChannelInterceptorBase.java:79) at org.apache.catalina.tribes.group.ChannelInterceptorBase.messageReceived(ChannelInterceptorBase.java:79) at org.apache.catalina.tribes.group.ChannelCoordinator.messageReceived(ChannelCoordinator.java:241) at org.apache.catalina.tribes.transport.ReceiverBase.messageDataReceived(ReceiverBase.java:225) at org.apache.catalina.tribes.transport.nio.NioReplicationTask.drainChannel(NioReplicationTask.java:188) at org.apache.catalina.tribes.transport.nio.NioReplicationTask.run(NioReplicationTask.java:91) at java.util.concurrent.ThreadPoolExecutor$Worker.runTask(ThreadPoolExecutor.java:885) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:907) at java.lang.Thread.run(Thread.java:619) Is there a way to resolve this issue? -- View this message in context: http://www.nabble.com/Tomcat-6-clustering-problem-tp18112263p18112263.html Sent from the Wicket - User mailing list archive at Nabble.com. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

RE: Tomcat 6 clustering problem
Well in a production situation there would be one host name used and failover would just change which server the requests to that host name get routed to. In that scenario the same cookies would be used so no problem. You should be able to use some trickery in your hosts file to mimic this. Add a host name (clustertest perhaps) that points to the first server's IP address, access the site, switch the IP address in the hosts file to the second server, verify that the second server is indeed hit and that the behavior is correct. I'm not sure if you are familiar with working with a hosts file so just know that on all Unix-like systems I have encountered it is found at /etc/hosts and on all Windows systems I have encountered it is found at C:\WINDOWS\system32\drivers\etc\hosts Larry -Original Message- From: Artem D.
