JPA: Could not pass Object from jpa to jms

[DRy]

Hi,

if I try to get an object from my jpa-resource and pass it to jms, the jms-message body is always null! I use the following route dfinition:

    from("jpa:com.itellium.eai.camelexample.entity.Customer?consumer.namedQuery=findAll&delay=10000&consumeLockEntity=true&consumeDelete=false")
            .routeId(JPAInRouteBuilder.ROUTE_ID)
            .transacted()
                .bean(messageLogBean)
                .to("jms:jpaIn?exchangePattern=InOnly&transacted=true&jmsMessageType=Object")
        .end();

If I look at the log, I can see that I get an object from the database (at the point of the bean-call):

2009-11-03 14:30:19,952 [1: JpaComponent] INFO  MessageLogBean                 - jpaIn,cadd73c8-edc5-4764-9ea2-bbeeb76bf9e8,Exchange[Message: com.itellium.eai.camelexample.entity.Customer@509bfc(oid=1,name=Name1,oversion=1)],Body[com.itellium.eai.camelexample.entity.Customer@509bfc(oid=1,name=Name1,oversion=1)]

I had tryed to use a route definition without any ben-call ... same effect ...

Im not sure ... but this may be a problem in the latest snapshot?

I guess JPA has instrumented and all sorts to those objects so you
cant serialize them and send them over the remote network.
Maybe there is something in the JPA API to detach or what it may be
called from the JPA EntityFactory so you can send it over network.

I used an old version of the object from our CVS-Repository that did not implement Serializable ...

But ... I could not see any exceptions when camel tries to put the message to the jms queue ... ?

Ah I have created a ticket for that so we can get this fixed.
