    EJB Deployment

    gtigti Newbie

      Hi,

      I'm new to jboss and I have to deploy a J2EE application.
      The WebModule, the JavaModule and the DataSource (Oracle) are working fine, but not the EJBModule

      I have this error :

      javax.naming.NameNotFoundException: ejb not bound

      I red about jboss.xml but I dunno where to put it, what do I have to put in it or if it's necessary to write it or not.

      Note that from the jmx-xonsole, I have the following :

      JMX MBean Operation Result
      Operation list()

      java:comp namespace of the OPCAISSE bean:
      +- env (class: org.jnp.interfaces.NamingContext)


      These two lines are displayed for each of my Java beans, so the EJB Module was correctly deployed I guess.

      Can someone help me with this please ? ...

      Thx in advance

            I think I have to write this fragment for each session bean or entity bean I have :


            <ejb-name></ejb-name>
            <jndi-name></jndi-name>
            <local-jndi-name></local-jndi-name>


            but I don't know what values I have to put in these tags, suppose I have an entity bean with name OPCAISSE in com.gti.iagence.ejb.opcaisse.entity package

            So the fragment will look like this ?


            <ejb-name>OPCAISSE</ejb-name>
            <jndi-name>com/gti/iagence/ejb/opcaisse/entity/OPCAISSE</jndi-name>
            <local-jndi-name>OPCAISSELocal</local-jndi-name>


            please help ....

              I don't know whether you are trying to deploy a session bean or entitry bean, but here is an example of both xml descriptors that works.

              
              Fragment from ejb-jar.xml

              <?xml version="1.0" encoding="Cp1252"?>
              <!DOCTYPE jboss PUBLIC "-/JBoss//DTD JBOSS 3.0//EN" "http://www.jboss.org/j2ee/dtd/jboss_3_0.dtd">
              
              
              <!-- Define security domain for the Milton application. -->
              <jboss>
               <security-domain>java:/jaas/Milton</security-domain>

              </jboss>
              
              


              This gives a full definition of a session bean, which references an entity bean.

              The entity bean in turn references a datasource defined in jboss.xml.

              You can use a reference in jboss.xml of form :-

              
               <entity>
               <ejb-name>milton/appmenu/menuoption</ejb-name>
               <jndi-name>another/jndi/name</jndi-name>
               </entity>
              
              


              but you only need this if you can't map your EJB names one-to-one with the JNDI names.

                I'm trying to deploy session beans and entity beans, but I dunno if I will need to reference them all in a jboss.xml file, my DS is working fine without that file.

                So ca, I deploy without using jboss.xml ?

                my ejb-jar.xml file looks like this :

                  You need to add all your beans to a jboss.xml file that maps EJB names to JNDI names. This is explained in the previous messages.

                  Furthermore I think you are looking up "ejb" instead of the actual bean you want, which would be something like "OPCAISSESB".
