    Problem: using modeshape with JBoss JNDI

    Jawwad Muzaffar Newbie

      Hi,

       

            I am new to ModeShape and was going through the tutorials for modeshape configurations etc. I read about working of Modeshape on JBoss AS 7 (JNDI). So I decided to give it a try. I followed all the steps provided on the page: https://docs.jboss.org/author/display/MODE/ModeShape+and+JBoss+AS7

       

      But unfortunately when I try to access modeshape through a simple servlet using the following code:

       

      --
      InitialContext context = new InitialContext();
      
      javax.jcr.Repository repository = (javax.jcr.Repository) context.lookup("jcr/sample");
      
      

      --

       

      , I get the following exception:

      ----------------------------------------------------------------------------------------------------------------------------

      java.lang.ClassCastException: org.modeshape.jcr.JcrRepository cannot be cast to javax.jcr.Repository

      com.virtualcode.modeshape.servlet.modeshapedemo.doGet(modeshapedemo.java:72)

      javax.servlet.http.HttpServlet.service(HttpServlet.java:734)

      javax.servlet.http.HttpServlet.service(HttpServlet.java:847)

      -----------------------------------------------------------------------------------------------------------------------------

       

      Any idea what I might be missing or what I might be doing wrong?

       

      Thanks in advance.

          Hi,

           

          Assuming your servlet is packaged in a .war file, make sure your war file does not include neither jcr-2.0.jar nor modeshape-jcr-api.jar nor any other ModeShape jars (if you're using Maven to build, those should be provided).

           

          Your web application should use the same jars that are installed/deployed in the AS7 server via the ModeShape module. In your war file,  just to add a dependency to those modules, either via a MANIFEST.MF, or a jboss-deployment-structure.xml file:

           

          <jboss-deployment-structure>

              <deployment>

                  <dependencies>

                      <module name="javax.jcr"/>

                      <module name="org.modeshape.jcr.api" services="import"/>

                      <module name="org.modeshape" services="import"/>

                  </dependencies>

              </deployment>

          </jboss-deployment-structure>

            Hi,

             

                      Thanks a lot for the response. Yes my servlet is packaged in a .WAR, but I am not using Maven. Also as recommended, I removed modeshape  and jcr2.0.jars  but the result is the same. i.e.

                       java.lang.ClassCastException: org.modeshape.jcr.JcrRepository cannot be cast to javax.jcr.Repository

             

                      Currently deployed jars (in the WAR) are:

              Do you need any of the above jars directly in your code ? (e.g. I'm seeing a lot of tika + dependencies there, which I'm not sure you need). Normally, most (if not all of these jars) are already deployed & installed in application server (some of them are present out-of-the-box, some are present after you've installed the ModeShape kit). So normally in your web application you just need a deployment descriptor which lists the correct module dependencies.

               

              What does you deployment descriptor look like ? (either MANIFEST.MF or jboss-deployment-structure.xml)

                Hi.

                 

                      Please ignore my last reply . There problem was that I was missing jboss-deployment-structure.xml in the WAR. After reading your reply, I checked and added the file. And now the code is working. Also about all the JARs, they were all added from the modeshape-3.1.3-dist download and yes most of them are not needed so I am removing jars that are not required.

                 

                       Thanks a lot for the help.

                  Hi,

                   

                  instead of a WAR  I'm using EJB as packaging type to reuse the jar file (containing the modeshape functionality) within a separate project.

                   

                  Unfortunately I'm getting the same error message on runtime:

                  java.lang.ClassCastException: org.modeshape.jcr.JcrRepository cannot be cast to javax.jcr.Repository


                  The file jboss-deployment-structure.xml is located in main/resources/META-INF/ within my jcr ejb packaging project.

                   

                  Kind regards,
                  Stefan
