EJB Passivation with Weblogic

When I have a stateful bean being passivated with Weblogic,  I get an error



<Error> <EJB> <010024> <Error during passivation:

java.io.NotSerializableException:
weblogic.connector.common.internal.ConnectionWrapper



I have the javax.resource.cci.Connection as an EJB instance variable.



Would appreciate some comments on this from folks who have been able to
passivate and activate stateful EJB using Weblogic.



Thanks in advance,
