Roland Burgermann updated EJBTHREE-1151:
----------------------------------------

    Description: 
I have tagged a class with the stereotype <<MappedSuperClass>> which holds some general attributes.

As described in the EJB3 specification i didn't have a DAO implementation class, because they are not necessary.

But when i try to deploy my application with JBoss 4.2.2.GA i got the following error:

2007-12-04 15:03:51,328 DEBUG [org.jboss.ejb3.Ejb3Module] Initialization failed jboss.j2ee:service=EJB3,module=ejb3xfire-core-1.0-SNAPSHOT.jar
java.lang.ClassNotFoundException: No ClassLoaders found for: com.company.samples.ejb3xfire.GeneralEntityDaoImpl

	at org.jboss.ejb3.Ejb3Deployment.deployBeansFromLib(Ejb3Deployment.java:465)
        .......

The whole stack trace can be found in the JBoss forum.

When i'm using JBoss 4.0.5.GA with the EJB3 RC9 Patch 1 then my application is startable.

Edit @ 10th December 2007:
I found a solution to solve this problem. 
I removed the following entry from the jboss.xml
        <session>
            <ejb-name>GeneralEntityDao</ejb-name>
        </session>

and removed the following entry from the ejb-jar.xml
        <session>
            <description>
                <![CDATA[
                
                ]]>
            </description>
            <ejb-name>GeneralEntityDao</ejb-name>
            <local>com.trinitec.samples.ejb3xfire.GeneralEntityDao</local>
            <ejb-class>com.trinitec.samples.ejb3xfire.GeneralEntityDaoImpl</ejb-class>
            <session-type>Stateless</session-type>
            <transaction-type>Container</transaction-type>
        </session>

After this two changes, i can start up JBoss with my application and everything is working fine for the moment.

Can i remove this two entries, or produce this another problem somewhere else?
And why is this running on JBoss 4.0.5.GA + EJB3 RC9 Patch 1?
Some checks are missing in JBoss 4.2.2.GA?
