Seam component instantiation problem

[bluetrade]

Hi,
I have a stateless seam component, that I use for my RMI stuff. Unlike my other components it doesn't seem to be instantiated, the entityManager (even though it contains @In(create=true)) is null, when I do a invocation from the client...

This component is the only component that is not mentioned anywhere inside my View, since it is pure RMI, I think that is the problem, so how could I "properly" instantiate it? Any clues?

Thanks

Is it in the same ejb-jar as the rest of the components?

Hi,

I am also having an issue with the Instantiation of the Seam Component..

I am trying the HelloWorld App in examples/remoting..

In the JBoss Server log i see the component..

13:43:42,828 INFO [Scanner] scanning: /D:/Projects/DPA/Jboss4.0.4/server/default/tmp/deploy/tmp43419MySeamTest.ear-cont

13:43:42,984 INFO [Initialization] done initializing Seam

Note: i have created an EAR App (MySeamtest) in NetBeans and hence the name MySeamTest.ear..

And when i run the App it is accepting the User Name and the throwing the following Exception..

Hi,

It seems the name should be MySeamTest/HelloAction/local instead of MySeamTest-war/HelloAction/local .

I made the change and still getting the error..!!

Hi All,

I Checked the JNDI MBean View and i see an entry for Hello Action..

Global JNDI Namespace

 +- XAConnectionFactory (class: org.jboss.mq.SpyXAConnectionFactory)
 +- MySeamTest (class: org.jnp.interfaces.NamingContext)
 | +- HelloAction (class: org.jnp.interfaces.NamingContext)
 | | +- local (proxy: $Proxy182 implements interface org.jboss.seam.example.remoting.HelloLocal,interface org.jboss.ejb3.JBossProxy,interface javax.ejb.EJBLocalObject)
 +- TopicConnectionFactory (class: org.jboss.naming.LinkRefPair)

pls let me know how to resolve this..

Thanks
Sateesh

You don't have the JBoss JNDI implementation in your classpath.

Hi Gavin,

Thanks for your reply..

I have included the jboss-ejb3-all.jar in the CLASSPATH and when i try to run the example i am getting the below Exception.

I have searched the forum for this and it seems a ClassLoading Issue and a JBoss bug .Not sure whether it is resolved or not..Could u pls let us know..

Use your debugger to resolve the problem. I very much doubt that this is due to any bug in JBoss.
