Deploying EJB under JBOSS-Tomcat bundle

Question

Hi
I am trying to perform a proof of concept using a simple EJB. I have downloaded and installed the jboss-3.2.0RC1_tomcat-4.1.18 co-bundle. Now, can anyone tell me how I deploy my simple EJB under this? Is there any documentation or tutorial anywhere?
Currently I have copied the following directory structure into %JBOSS_HOME%\server\default\deploy
Login.war
    {jsp files}
    au
        com
            keytrust
                {class files}
    META-INF
        ejb-jar.xmlThis deploys without error, but gives me an exception "javax.naming.NameNotFoundException: ejb not bound" when I try to access the ejb.
Can anyone help me, or direct me to an appropriate reference?
Thanks
John

Hi.
Here is the session portion from one of my working ejb-jar.xml descriptors:
    <session>
      <display-name>ConferenceController</display-name>
      <ejb-name>ConferenceControllerEJB</ejb-name>
      <home>com.gumbtech.conf.ejb.ConferenceControllerHome</home>
      <remote>com.gumbtech.conf.ejb.ConferenceController</remote>
      <ejb-class>com.gumbtech.conf.ejb.ConferenceControllerBean</ejb-class>
      <session-type>Stateful</session-type>
      <transaction-type>Bean</transaction-type>
      <ejb-ref>
        <ejb-ref-name>ejb/ConferenceHome</ejb-ref-name>
        <ejb-ref-type>Entity</ejb-ref-type>
        <home>com.gumbtech.conf.ejb.ConferenceHome</home>
        <remote>com.gumbtech.conf.ejb.Conference</remote>
        <ejb-link>ConferenceEJB</ejb-link>
      </ejb-ref>
      <security-identity>
        <description></description>
        <run-as>
          <description></description>
          <role-name>admin</role-name>
        </run-as>
      </security-identity>
    </session>And the matching portion from it's sister jboss.xml descriptor:
  <session>
    <ejb-name>ConferenceControllerEJB</ejb-name>
    <jndi-name>ConferenceControllerHome</jndi-name>
    <ejb-ref>
      <ejb-ref-name>ejb/ConferenceHome</ejb-ref-name>
      <jndi-name>ejb.ConferenceHome</jndi-name>
    </ejb-ref>
    <ejb-ref>
      <ejb-ref-name>ejb/StatelessConferenceHome</ejb-ref-name>
      <jndi-name>ejb.StatelessConferenceHome</jndi-name>
    </ejb-ref>
    <resource-ref>
      <jndi-name>java:/OracleDS</jndi-name>
    </resource-ref>
  </session>After losing an entire head of hair over this, the only thing that worked for me, thanks to no documentation anywhere, was to ensure that the EJB portion of my ejb-name that you see below was present on the end of each and every bean I declared in my descriptors ...
<ejb-name>ConferenceControllerEJB</ejb-name>...and that this name was identical in both jboss.xml and ejb-jar.xml.
Notice too that the newer jboss uses dots instead of slashes in the jndi-name of another ejb I am referencing from my bean:
<jndi-name>ejb.ConferenceHome</jndi-name>You don't reference another bean yet, but if you do ...this will hang you for weeks as well until you get that dot in there.
Furthermore, I found was so paranoid by this point that I never again wavered from keeping the following naming convention for my class names (??):
The remote interface: MyThing
The bean implementation: MyThingBean
The home interface: MyThingHome
Then, finally ...the darn thing worked.
They use reflection maybe ?
Hope this might help.
