How to deploy 2 EJB's in separate jars

[le taylom]

Hi,
I have successfully deployed 2 session ejb's in the same jar file, i.e. with one ejb-jar.xml and one weblog-ejb-jar.xml. And get get the ejb's to communicate with each other.
Now I want to be able to compile and deploy the 2 ejb's in separate jar files as part of an ear file.
My method so far is this:
I have split the ejb-jar.xml file into two, for each ejb, and also the weblogic-ejb-jar.xml file into two for each ejb.
I then compiled the ejb source files and packaged each ejb up with its respective deployment descriptors into two separate .jar files.
I then want to run weblogics ejbc on each .jar file in turn so that the resultant .jar files (with newly created stubs/skels) can be packaged into an .ear to be easily deployed into weblogic.
I try and run the ejbc command on the first of the .jar files and i get the error:
ERROR: Error from ejbc:
In ejb-jar.xml, the EJB 'SessClient' contains an invalid ejb-link in ejb
-ref 'ejb/SessLogHome'. No EJB with ejb-name 'IntellectStateless.jar#SessLog' co
uld be found.
ERROR: ejbc found errors
My ejb-jar.xml file for this ejb is:

  
<ejb-jar>
  <enterprise-beans>
    <session>
      <ejb-name>SessClient</ejb-name>
      <home>intellectsession.sessiontwo.SessClientEntHome</home>
      <remote>intellectsession.sessiontwo.SessClientEnt</remote>
      <ejb-class>intellectsession.sessiontwo.SessClientEntBean</ejb-class>
      <session-type>Stateless</session-type>
      <transaction-type>Container</transaction-type>
      <ejb-ref>
        <ejb-ref-name>ejb/SessLogHome</ejb-ref-name>
        <ejb-ref-type>Session</ejb-ref-type>
        <home>intellectsession.stateless.SessLogHome</home>
        <remote>intellectsession.stateless.SessLog</remote>
        <ejb-link>IntellectStateless.jar#SessLog</ejb-link>
      </ejb-ref>
    </session>
  </enterprise-beans>
  <assembly-descriptor>
    <container-transaction>
      <method>
<ejb-name>SessClient</ejb-name>
<method-name>*</method-name>
      </method>
      <trans-attribute>Required</trans-attribute>
    </container-transaction>
  </assembly-descriptor>
</ejb-jar>

and both of my .jar files are in the same directory when I run the ejbc command.
I'm sure this can be done but I just think i'm not doing it in the right order maybe??
Anyway pointers will be gr8ly appreciated.
Cheers

HI,
take out the ejb-ref tag, you�re not required to provide it.

Okay here is the solution to how to achieve the problem I encountered above:
I am compiling my ejb.jar files using the weblogic.ejbc compiler, obviously I am deploying on weblogic here.
This section:

<ejb-ref>
  <ejb-ref-name>ejb/SessLogHome</ejb-ref-name>
  <ejb-ref-type>Session</ejb-ref-type>
  <home>intellectsession.stateless.SessLogHome</home>
  <remote>intellectsession.stateless.SessLog</remote>
  <ejb-link>IntellectStateless.jar#SessLog</ejb-link>
</ejb-ref>

must have JUST the <ejb-link/> tag removed from the ejb-jar.xml file. And then the weblogic-ejb-jar.xml file MUST look like this:

<weblogic-ejb-jar>
    <weblogic-enterprise-bean>
        <ejb-name>SessClient</ejb-name>
        <reference-descriptor>
          <ejb-reference-description>
            <ejb-ref-name>ejb/SessLogHome</ejb-ref-name>
            <jndi-name>SessLog</jndi-name>
          </ejb-reference-description>
        </reference-descriptor>
        <jndi-name>SessClient</jndi-name>
    </weblogic-enterprise-bean>
</weblogic-ejb-jar>

Note the <refererence-descriptor> tag as the important part.
After these changes, the 2 ejb.jar files can be compiled using the weblogic.ejbc tool, thus supplying the stubs/skels, and then the resultant two ejb.jar files can be added to the EAR file and deployed to weblogic.
Result: 2 ejb's in separate jars, in one EAR file, talking to each other.

The reason for this is because the specification specifies <ejb-link> as only being able to be used when the EJB's are part of the same Jar. Otherwise you must use the <ejb-ref> if you want this explicit linking between ejbs to be performed
