    Configuration of JBoss/Tomcat

    Rajiv Newbie

      Hi All,
      I have developed servlets, jsp pages and ejbs (entity bean and session bean) in weblogic 6.1, it

      is working fine with bea's weblogic 6.1 application server.

      Deployment descriptors for entity bean are
      ejb-jar.xml,
      weblogic-ejb-jar.xml
      weblogic-cmp-rdbms-jar.xml

      Deployment descriptors for session bean are
      ejb-jar.xml,
      weblogic-ejb-jar.xml


      Now i want to execute this code in to jboss application server, for that

      I have downloaded JBoss 3.0.0 (Application server) and tomcat 4.0.4 separately and loaded in

      different folders.
      Now when i tried to access ejbs from servlet it is not identifying my ejbs. giving

      namenotfoundexception.

      1)What are the deployment descriptor files to write for jboss..?

      2)Where exactly i want to keep my ejbs in jboss..?

      3)How to create stubs and skeletons in jboss..?

      4)How to deploy the ejbs..?

      5)What are the initial context properties for jboss?
      i have set Context.INITIAL_CONTEXT_FACTORY,"org.apache.naming.java.javaURLContextFactory"
      and i don't no Context.PROVIDER_URL properties in weblogic i was using t3://192.168.0.8:7001 as

      Context.PROVIDER_URL

      6) What are the xml files i need to modify in order to deploy the bean

      i have started both servers (jboss server and tomcat server) and placed beans jar file in

      E:\jboss-3.0.0\server\default\deploy folder

      Any help on this regard, will be appreciated greatly,

      Thanks in advance
      Best Wishes,
      Dinakar

          You can find the dtds for the descriptors
          in ${jboss.home}/docs/dtd

          There is some explanation in the quickstart docs
          http://sourceforge.net/project/showfiles.php?group_id=22866

          Somebody has provided a generic deployer.
          It can convert weblogic descriptors into jboss
          descriptors as you deploy the jars.

          I'm not sure how complete it is.
          You have to get it from CVS.
          http://cvs.sourceforge.net/cgi-bin/viewcvs.cgi/jboss/contrib/varia/src/resources/deployment/
          http://cvs.sourceforge.net/cgi-bin/viewcvs.cgi/jboss/contrib/varia/src/main/org/jboss/varia/deployment/

          You don't need them.

          See question 2

          This might help you setup an external tomcat

          See question 2
          If you have problems look in server\default\log\server.log

            Hi Blighty
            I am rephrasing my problem hope you get a better idea:

            I am trying to access a simple stateless ejb from the servlet, for that, i have developed following files:

            remote interface
            home interface
            bean implementation
            &
            ejb-jar.xml
            jboss.xml (double checked the jndi name)

            and created a jar of these files and kept in the respected folders.

            Now i deployed, this jar file in - %JBOSS_HOME%\server\default\deploy,

            started the jboss server, it is successfully deploying my ejb,

            moving to the client side, i developed the servlet,hard coded the initial context in the serverlet.
            it is as follows:

            prop.setProperty("java.naming.factory.initial","org.apache.naming.java.javaURLContextFactory");
            prop.setProperty("java.naming.provider.url","192.168.0.8:1099");
            prop.setProperty("java.naming.factory.url.pkgs","org.jboss.naming:org.jnp.interfaces");

            now, when i start the tomcat server and try to access ejb from the servlet it is throwing an exception like this.

            javax.naming.NameNotFoundException: Name HelloHome is not bound in this Context

            1)I have loaded tomcat in different drive an jboss in different drive...now how configure them ??? ...how to make them communicate each other???

            2) is mbean, necessarily required...? how can we work without that.

            Help in this regard, will appreciated greatly.

              Try listing the bindings from your initial context
              to make sure it is actually JBoss.

              for (NamingEnumeration e = ctx.list(""); e.hasMore();)
              System.out.println(e.next());

              Did you read the other link about configuring external
              tomcat?

              Does the full stack trace mention org.jnp.* classes?

                Hi Adrian,

                Thanks alot for your prompt help and guidance. I really appreciate it and thanks once again.

                I tried to implement your suggestion, and got a exception:

                javax.naming.NameNotFoundException: Name HelloHome is not bound in this Context

                I have pointed the JNDI as below:
                "my jndi name-->HelloHOme"

                for (NamingEnumeration e = ctx.list("HelloHome"); e.hasMore();)
                System.out.println(e.next());

                AWaiting for your advice,

                Thanks in advance,
                regards,

                  I really did mean list("") so you get a full of list of
                  what is available.

                    Hi Adrian,
                    I tried to implement your suggestion, and got no listing. it is returning--> null..?? (ctx.list("")), ok...

                    For your reference:
                    Tomcat server is using, the initial context as:
                    org.apache.naming.java.javaURLContextFactory

                    JBoss as:
                    org.jnp.interfaces.NamingContextFactory

                    1) Does it, creats any problem..?????? if so, How to resolve that.

                    When I tried to hardcode, the InitialContext as(org.jnp.interfaces.NamingContextFactory) in the servlet, I got InitialConextException????.
                    Rootexception is ClassNotFoundException (org.jnp.interfaces.NamingContextFactory)

                    AWaiting for your advice,
