    Cannot find environment parameter

    Shaun Appleton Newbie

      I setup an environment property in my ejb-jar.xml file as-

      <enterprise-beans>

      ...
      <!--This element is an environment variable only available in jlidState-->
      <env-entry>
      This element is an environment variable representing the start ID of the JLID entry. For example if the startJLID is 50000 then only JLIDS above 50000 should be displayed.

      <!--The JNDI location for the environment variable is java:comp/env/startJLID-->
      <env-entry-name>startJLID</env-entry-name>
      <env-entry-type>java.lang.String</env-entry-type>
      <env-entry-value>50000</env-entry-value>
      </env-entry>

      </enterprise-beans>

      and try and access it in my code by

      /*
      * get the startJLID environment variable from ejb-jar.xml
      * /
      Context initCtx = new InitialContext();
      String startJLID = (String) initCtx.lookup("java:/comp/env/startJLID");
      System.out.println("startJLID : "+startJLID);

      but I get a javax.naming.NameNotFoundException : startJLID not bound

      I'm using JBoss 3.0.3 + tomcat (this is virtually copied straight out of the Mastering EJB book by Roman et al)

      Any ideas what's wrong?

      Thanks in advance,
      Shaun

              Hi,

              try to look at JNDIView (jmx-console) where the env var. is registered.

                The error was in the code!

                String startJLID = (String) initCtx.lookup("java:/comp/env/startJLID");

                String startJLID = (String) initCtx.lookup("java:comp/env/startJLID");

                Schoolboy error on my part!
