    StatefulSession caching ejb references

    g king Newbie

      Hi,

      I have a stateful session bean which holds references to various ejb's and performs queries against them. When I deploy the app several times one set of ejb's stop working. The only way to get them to work again, randomly, is to change the problem ejb's, so as, I guess, to give them a different footprint.

      What's the cause?

      My deployment looks like the following:
      app.ear
      -jar1-ejb.jar
      -jar1-ejb-client.jar
      -jar2-ejb.jar
      -jar2-ejb-client.jar
      -app.war

      app.war
      -war/web-inf/lib/
      --jar1-ejb-client.jar
      --jar2-ejb-client.jar

      jar2-ejb.jar's ejb-jar.xml references classes in jar1-ejb.jar, like so:

      <ejb-relation>
       <ejb-relation-name>test-site-test-price-lists</ejb-relation-name>
       <ejb-relationship-role >
      
      <ejb-relationship-role-name>test-has-site-test-price-list</ejb-relationship-role-name>
       <multiplicity>One</multiplicity>
       <relationship-role-source >
       <ejb-name>TestEJB</ejb-name> - jar2-ejb.jar
       </relationship-role-source>
       <cmr-field >
       <cmr-field-name>siteTestPriceList</cmr-field-name>
       <cmr-field-type>java.util.Collection</cmr-field-type>
       </cmr-field>
       </ejb-relationship-role>
       <ejb-relationship-role>
      
      <ejb-relationship-role-name>site-test-price-list-has-test</ejb-relationship-role-name>
       <multiplicity>Many</multiplicity>
       <relationship-role-source >
       <ejb-name>SiteTestPriceListEJB</ejb-name> - jar1-ejb.jar
       </relationship-role-source>
       <cmr-field >
       <cmr-field-name>testId</cmr-field-name>
       </cmr-field>
       </ejb-relationship-role>
       </ejb-relation>
      


      Checking the jmx-concolse I see that since the SiteTestPriceListEJB is listed in both jar's ejb-jar.xml file it is deployed twice...

      I wonder if that might be causing my grief?

      Thanks for any suggestions!
