[jboss-user] [JBoss Seam] - Re: BookingListAction SFSB and Serializable interface

[asookazian]

I am doing some root cause analysis here to determine the problem.

I removed all references to Seam @Logger and Seam Log in both SFSB's involved in this use case.

I was still able to reproduce the log4j related exception after passivation occurs and then running another test case:

Caused by: org.jboss.serial.exception.SerializationException: Could not create instance of org.apache.log4j.Logger - org.apache.log4j.Logger

I did a search for keyword "log4j" in my project and found a log4j.xml file in the {projectName}/bootstrap folder.  Not sure exactly what the bootstrap is used for but I think it was new for Seam 2.0.  Probably for bootstrapping JPA for JavaSE project?  Anyways, that log4j.xml and bootstrap folder are not in my EAR in JBoss default/deploy folder.

Root cause is unknown at this time...
