Migrating EJB 2.0 on JBoss AS 7.1CR1

[aupadhyaya2002]

Hi,

At the moment I am porting EJB 2.0 to JBoss As 7.1 and  having the some issues during deployment. I have attached the below logs.

java:global/tcc/tcc-ejb/StaticDataController!com.ebrd.tcc.ejb.staticdata.StaticDataControllerLocal
java:app/tcc-ejb/StaticDataController!com.ebrd.tcc.ejb.staticdata.StaticDataControllerLocal
java:module/StaticDataController!com.ebrd.tcc.ejb.staticdata.StaticDataControllerLocal
java:global/tcc/tcc-ejb/StaticDataController!com.ebrd.tcc.ejb.staticdata.StaticDataControllerLocalHome
java:app/tcc-ejb/StaticDataController!com.ebrd.tcc.ejb.staticdata.StaticDataControllerLocalHome
java:module/StaticDataController!com.ebrd.tcc.ejb.staticdata.StaticDataControllerLocalHome
java:global/tcc/tcc-ejb/StaticDataController!com.ebrd.tcc.ejb.staticdata.StaticDataControllerRemote
java:app/tcc-ejb/StaticDataController!com.ebrd.tcc.ejb.staticdata.StaticDataControllerRemote
java:module/StaticDataController!com.ebrd.tcc.ejb.staticdata.StaticDataControllerRemote
java:global/tcc/tcc-ejb/StaticDataController!com.ebrd.tcc.ejb.staticdata.StaticDataControllerHome
java:app/tcc-ejb/StaticDataController!com.ebrd.tcc.ejb.staticdata.StaticDataControllerHome
java:module/StaticDataController!com.ebrd.tcc.ejb.staticdata.StaticDataControllerHome

I have got below entries in jboss.xml

  <session>
   <ejb-name>StaticDataController</ejb-name>
   <jndi-name>com/ebrd/tcc/StaticDataController</jndi-name>
  </session>

I would like to know whether we can use EJB 2 in JBoss 7.1CR1. I have read some of the similar issues, but not sure whether EJB 2 porting issue in JBoss 1.7 has been addressed.

Thanks.

AS7 no longer supports jboss.xml. You'll need a jboss-ejb3.xml. Furthermore, the jboss-ejb3.xml does not support the jndi-name element to bind to custom JNDI names. Instead, you can use the following approach/trick in ejb-jar.xml to bind to custom JNDI names in the java:global JNDI namespace:

<ejb-jar> <!-- Use the correct dtd/xsd here -->
    <enterprise-beans>
        <session>
            <ejb-name>SimpleBean</ejb-name>
            <home>org.jboss.as.test.integration.ejb.injection.ejbref.HomeInterface</home>
            <remote>org.jboss.as.test.integration.ejb.injection.ejbref.RemoteInterface</remote>
            <local-home>org.jboss.as.test.integration.ejb.injection.ejbref.LocalHomeInterface</local-home>
            <local>org.jboss.as.test.integration.ejb.injection.ejbref.LocalInterface</local>
            <ejb-class>org.jboss.as.test.integration.ejb.injection.ejbref.SimpleBean</ejb-class>
            <session-type>Stateless</session-type>
            <ejb-ref>
                <ejb-ref-name>java:global/MyCustomJNDIName</ejb-ref-name>
                <ejb-ref-type>Session</ejb-ref-type>
                <home>org.jboss.as.test.integration.ejb.injection.ejbref.HomeInterface</home>
                <remote>org.jboss.as.test.integration.ejb.injection.ejbref.RemoteInterface</remote>
            </ejb-ref>

        </session>
...

I haven't given it a try. See if it works for you.

Yes

Do we have to migrate the code also ? Or is rewritting the EJB descriptors the 'only' work we have to do ?

[jaikiran]

If your application was using spec specified APIs then you don't need any change. However, if your application had any server specific code then it will have to be reviewed in context of AS7.

That is fast answer !!

The code is 'per the specs' as it was running in a least 2 different containers.

So I need to migrate my jboss deployement descriptors.

Cool
