    EJB 3.0 Help!!!

    Alvaro Martinez Newbie

      Hi,

      Concerning my last post "Problems on EJB3 - Application", last night I installed the Jboss AS 4.0.3. sp1 (Production) and I did it with the .jar installer.

      As I read in one of the posts in the forum, I just installed de AS and nothing else.
      Then I packaged the application and deployed it but the problem persists.

      The result at the debugging stage was the following


      type Exception report
      message
      description The server encountered an internal error () that prevented it from
      fulfilling this request.
      exception
      javax.servlet.ServletException: XCellDomRemote.OCiudades not bound

      org.apache.tomcat.util.net.MasterSlaveWorkerThread.run(MasterSlaveWorkerThread.java:112)
      java.lang.Thread.run(Thread.java:595)

      note The full stack trace of the root cause is available in the Apache
      Tomcat/5.5 logs.

      Apache Tomcat/5.5


      I want to note that when the new AS installation started, it presented the following messages:

      what tells me that the OCiudades bean is registered and created.

      as you might see the OCiudades not bound exception persists and I don´t figure out how to solve it. I´m open to suggestions.

          Hi,

          Yesterday I included in my appl the persistence.xml file:

          <?xml version="1.0" encoding="UTF-8"?>
          <entity-manager>
           <name>OEMManager</name>

           <property name="hibernate.hbm2ddl.auto" value = "none"/>
           <property name="hibernate.connection.release_mode" value="auto"/>
           <property name="hibernate.show_sql" value="true"/>
           <property name="hibernate.default_schema" value="CellDom"/>
           <property name="hibernate.generate_statistics" value="true"/>
           <property name="hibernate.use_sql_comments" value="true"/>
           <property name="hibernate.cache.provider_class" value="org.jboss.ejb3.entity.TreeCacheProviderHook"/>
           <property name="hibernate.treecache.mbean.object_name" value="jboss.cache:service=EJB3EntityTreeCache"/>
           </properties>
          </entity-manager>


          and packaged it in a .par file together with the entity beans OCuidad and OApplProperty which a I show a fragment in the previous post.

          I also created the file CellDom-ds.xml and put it at the {jboos-home}/server/all/deploy. The contents of this file are:

          <?xml version="1.0" encoding="UTF-8"?>

           </mbean>
          
          </datasources>


          and I also included the oracle 10g jdbc library "ojdbc14.jar" at the {jboos-home}/server/all/lib directory.

          finally I packaged the app in a .ear, .par, .ejb3 (with the corresponding Interfaces and session beans) and .war (with the servlet) files
          When I deployed them these are the results:

          I have looked up in the Jboss & Hibernate tutorials and guides, for an error messages guide where errors and possible solutions, are explained, (Just as in Oracle documentation), but I have found nothing about. I wish you to help me please to solve these problems or direct me to a guide where I can find possible solutions.

          Thanks in advance for your help.
