Judging from the stack trace, you have an instance variable holding a Connection. Connections aren't serializalbe, thus the error on passivation. Don't have a instance variable for your connection: just get it, use it, and close it within one method call. david jencks On 2001.07.31 19:09:55 -0400 yan fan wrote: > Hi! > I am sorry , when I use session bean and jdbc , I > meet a exception like following: > > [Container factory] java.rmi.ServerException: Could > not passivate; nested exception is: > [Container factory] > java.io.NotSerializableException: > org.opentools.minerva.jdbc.xa.wrapper.XAClientConnection > [Container factory] java.io.NotSerializableException: > org.opentools.minerva.jdbc.xa.wrapper.XAClientConnection > [Container factory] at > java.io.ObjectOutputStream.output > Object(ObjectOutputStream.java:1148) > [Container factory] at > java.io.ObjectOutputStream.writeO > bject(ObjectOutputStream.java:366) > [Container factory] at > java.io.ObjectOutputStream.output > ClassFields(ObjectOutputStream.java:1841) > [Container factory] at > java.io.ObjectOutputStream.defaul > tWriteObject(ObjectOutputStream.java:480) > [Container factory] at > java.io.ObjectOutputStream.output > Object(ObjectOutputStream.java:1214) > [Container factory] at > java.io.ObjectOutputStream.writeO > bject(ObjectOutputStream.java:366) > [Container factory] at > org.jboss.ejb.plugins.StatefulSes > sionFilePersistenceManager.passivateSession(StatefulSessionF > ilePersistenceManager.java:278) > [Container factory] at > org.jboss.ejb.plugins.StatefulSes > sionInstanceCache.passivate(StatefulSessionInstanceCache.jav > a:54) > [Container factory] at > org.jboss.ejb.plugins.AbstractIns > tanceCache$1.execute(AbstractInstanceCache.java:668) > [Container factory] at > org.jboss.util.WorkerQueue$QueueL > oop.run(WorkerQueue.java:199) > [Container factory] at > java.lang.Thread.run(Thread.java: > 484) > > > __________________________________________________ > Do You Yahoo!? > Make international calls for as low as $.04/minute with Yahoo!
