    jboss 4.2 Hibernate 3.2 entity mapping problem

    Clair Graham Newbie

      I am trying to get a test jsf application to work on the standard jboss 4.2.0 AS server. I am using eclipse as the IDE. I set the build path in my eclipse project to point to jboss/default/lib jar files for hibernate and other required jars.

      when I deployed the application everythings works as it should until I make a call from a backing bean to query or load a hibernate class. I get the following error: "org.hibernate.MappingException: Unknown entity: com.ipi.InformationPortal.model.People".

      The configuration snippets are:

          The hibernate mapping file didn't display so I will try to cut and paste again.

                  The files look right to me. The exception you are seeing usually shows up when the class is not mapped through the hibernate.cfg.xml file. But i see, you have already done that. Are you sure, while creating the session factory, this hibernate.cfg.xml is being picked up? I mean, is there any other hibernate.cfg.xml in your classpath which might be getting picked up by the application

                    I checked and it is the only hibernate.cfg.xml file in the war file and work sub-directory in jboss default sub-directory. I don't see any messages indicating that the hibernate configuration files are missing or have a problem. I hope someone can see what I am missing. Thanks you for your feedback.

                      Could you try deleting the hibernate.properties and maintain just the hibernate.cfg.xml? Hibernate uses the hibernate.cfg.xml by overriding the hibernate.properties when both the files are present. Just want to make sure that the cfg.xml is being used and not the properties file. I guess that the hibernate.properties is being used because otherwise i would have expected some errors being thrown up since your cfg.xml does not contain any dialect/driver/connection url related information.

                        So, I deleted the hibernate.properties file and added the jdbc connection info to the hibernate.cfg.xml file. The file is still at the root of the web app (same directory as the jsp/jsf files). There appears to be a problem with jboss 2.4.0 and hibernate.

                        you can see in the stack trace that it didn't find the hibernate.properties file however it doesn't seem to be reading the hibernate.cfg.xml file which has the dialect value set. Do you know for sure where the hibernate.cfg.xml file should be located on jboss?

                          The hibernate.cfg.xml should be at the root of the application, the same place where your hibernate.properties was present earlier. Is your application an ear or a war file. If so can you post the output after following the steps below:

                          - Open a command prompt
                          - From the command prompt move to %JBOSS_HOME%/server/default/deploy
                          - Run the following command:

                          jar -tf myApp.war


                          where myApp.war is the name of your application. Post the output. The output will display the contents of your application.

                            Its now working. I made the following change to the backing bean:

                            was
                             SessionFactory mdpsf = cfg.buildSessionFactory();
                            now
                             SessionFactory mdpsf = cfg.configure().buildSessionFactory();
                            


                            It appears the configuration parameter weren't being read in the first example of creating a SessionFactory. By adding the method configure() the mapping was found.

                            The URL you provided "http://www.hibernate.org/hib_docs/reference/en/html/session-configuration.html" was very helpful.

                            Again, thanks for all the help!
