new problem with RMIConnectionFactory

[ppetit]

I have a MDB that worked very fine before I download the JBoss 3.0.0 alpha following the tag on the main download page.
with the new build of this 3.0.0 alpha release I get the following :
javax.naming.NamingException: Invalid reference. Error: org.jboss.mq.GenericConnectionFactory; local class incompatible : stream classdesc serialVersionUID = -6897993188562554891, local class serialVersionUID = 7049717886891616346
at org.jboss.mq.referenceable.ObjectRefAddr.extractObjectRefFrom(ObjectRefAddr.java:82)
at org.jboss.mq.referenceable.SpyConnectionFactoryObjectFactory.getObjectInstance(SpyConnectionFactoryObjectFactory.java:44)
at javax.naming.spi.NamingManager.getObjectInstance(NamingManager.java:304)
at org.jnp.interfaces.NamingContext.lookup(NamingContext.java:446)


here is the code snippet that is reponsible for this error messahe :
...
if( topicFactory == null )
{
try
{
// Get the connection factory
topicFactory = (TopicConnectionFactory)jndiContext.lookup("RMIConnectionFactory");

}
catch( NamingException e )
{
Saga_util.panicDialog( className +
"TopicConnectionFactory Erreur de nommage : " + e );
}
}
...

It looks like the RMIConnectionFactory returns a "local" interface instead of a remote one like before.
Is that true? and do I have to modify the way I lookup the JNDIcontext or what?

Help is welcomed !

thanks, Philippe

It sounds like you are using 2.4 classes on the
client and 3.0 classes on the server.

In this case local=client

sorry... I don't understand...
my client is a remote swing app that makes a jndi lookUp on RMIConnectionFactory layer...
where is the diff between 2.4 classes and 3.0 ?
I add this code was perfectly running with a 3.0 alpha (I don't know the build number) and I downloaded a fresher 3.0 alpha build, and it doesn' work anymore since this knew 3.0 alpha...
so... what has been changed ?

[ppetit]

I rebuilt all my packages : my MDB package and the client side and redeployed... but it's not working best, I still have the same issue with the RMIConnectionFactory.

[hchirino]

the jbossmq-client.jar that is in the client's classpath needs to be the same that is in the server's /client directory.
