Failover not working InvalidClassException (Log4JLogger)

[carstenrudat]

Hi all,

I have a smal cluster of 2 JBoss 4.2.1.GA running and I tried to test a transparent failover (e.g. stopping node2). It seems that JBoss tried to load the session on node1, but that fails with:

[JBossCacheService] loadSession(): id: oCzamsCP7SqX7LZBJiaYWA**exception occurred during serialization: java.io.InvalidClassException: org.apache.commons.logging.impl.Log4JLogger; local class incompatible: stream classdesc serialVersionUID = 1, local class serialVersionUID = 2930996631104246328


Is there a problem having a Log variable in JSF-managed-beans or other pojos used in my tomcat-container?

Could you give me a tip, what I should do?

Thanks,
Carsten

Hi,

I fixed this - I had a commons-logging-x.jar in my WEB-INF/lib.

But after removing this, I get another error:


WARN [TreeCache] node /JSESSION/localhost/genloop-demo/8gZM8DrZOd0IGqYY6C3Luw** not found

I have two jboss-4.2.1.GA (./run.sh -c all -b ip_node1/ip_node2) running. After shutting down node1 and submitting a request, I get this error on node2.
What does this "localhost" mean and how can I get a session-string that allows transparent failover?

To add some information, I run a JSF-application with tomahawk and client-side saving (javax.faces.STATE_SAVING_METHOD - client).

Thanks for any help to get this work.
Carsten
