Question

NameNotFoundException although bean is deployed succesful

Asked by: Crazy_Bytes

Hi,

I have a problem where I can't the cause for it. I have a JBoss 4.2.3 application server running
in a clustered configuration. Ihave about 160 session and entity beans and also 2 ears running with no problem. Due to some open projects I needed to create 2 new entity beans.

98% of the beans stil use thel EJB 2.0 spec, a few use EJB 3.0 spec. The new beans also use the EJB 2.0 spec. Both beans are deployed succesful. But the moment I try to create a home instance I receive a NameNotFoundException.

This is what I get during server start:
...
17:34:16,480 INFO  [EjbModule] Deploying CoReductionDetail
17:34:16,511 INFO  [ProxyFactory] Bound EJB Home 'CoReductionDetail' to jndi 'CoReductionDetail'
17:34:16,511 INFO  [EJBDeployer] Deployed: file:/C:/jboss-4.2.3.GA/server/dev/deploy/CoReductionDetailEnterpriseBean.jar

17:34:16,668 INFO  [EJBDeployer] Deployed: file:/C:/jboss-4.2.3.GA/server/dev/deploy/CoReductionHeadEnterpriseBean.jar
...

This is the message I recieve when I try to instanciate the bean:
java.rmi.ServerException: EJBException:; nested exception is:
      javax.ejb.EJBException: Could not instantiate bean; nested exception is: javax.ejb.EJBException: javax.ejb.EJBException: javax.naming.NameNotFoundException: CoReductionHead not bound; nested exception is: javax.ejb.EJBException: javax.naming.NameNotFoundException: CoReductionHead not bound; nested exception is: javax.naming.NameNotFoundException: CoReductionHead not bound

      at org.jboss.remoting.transport.socket.ServerThread.run(ServerThread.java:173)

I checked the ejb-jar.xml and jboss.xml deployment descriptors over and over. I even wrote complete new, with no changes.

When I shut the server I get the folowing messages:
...
17:40:53,839 INFO  [EJBDeployer] Undeploying: file:/C:/jboss-4.2.3.GA/server/dev/deploy/CoReductionHead EnterpriseBean.jar
17:40:53,839 INFO  [ProxyFactory] Bound EJB Home 'CoReductionHead' to jndi 'CoReductionHead'
17:40:53,855 INFO  [ProxyFactory] Unbind EJB Home 'CoReductionHead' from jndi 'CoReductionHead'
17:40:53,855 INFO  [EjbModule] Undeployed CoReductionHead
17:40:53,855 INFO  [EJBDeployer] Undeploying: file:/C:/jboss-4.2.3.GA/server/dev/deploy/CoReductionDetailEnterpriseBean.jar

17:40:53,871 INFO  [EjbModule] Undeployed CoReductionDetail
...

When the sever is running I can see the bean in the JMX console.

To me this exception makes no sense, since the console tells that the beans are deployed succesful.

I also checked the lookup of the beans, the are identical with the lookup of the other EJB 2.0 beans, ecept that the name is different. I also checked severel times the Name of the bean inside the source code of the lookup.

Has anybody the slightest idea why this exception occurs?

Thanks,
CB

Have you put the entries in ejb-jar.xmls ?

 

by: Crazy_BytesPosted on 2009-06-23 at 01:20:00ID: 24689903

I did, I attached both deployment descriptors for the EntityBean CoReductionHead.
The descriptors for CoReductionDetail are identical except for the name.

The entry
            <prim-key-class>com.crazy_bytes.business.promotion.ejb.CoReductionHeadEJB</prim-key-class>
is wrong.
The right entry is:
            <prim-key-class>com.crazy_bytes.business.promotion.ejb.CoReductionHeadPK</prim-key-class>

But my problem still remains.

Greetings,
CB

I used the opportunity to switch the affected beans from ejb2.0 to ejb3.0. Although I still don't know why the problem occured I found a way around it.
