    Hibernate Configurations problem

    Paul Keogh Newbie

      JBT 3.00 CR2, Eclipse 3.4.2

      When I open the Hibernate Configurations to view and expand a configuration created with seam-gen (through Eclipse) from Sean 2.1.1 GA, I
      get an error of;

      Error while opening console configuration: xxx-ejb

      Reason:

      org.hibernate.console.HibernateConsoleRuntimeException: Persistence Unit not found: 'null'
      <no message>

      any ideas on how to fix ???

          hmm - should just work.

          Project > Clean

          and Refresh the console config


          if that does not help run ant test (that should no longer be a requirement, but it was in earlier versions)

            Thanks for the reply Max. Unfortunately your suggestion does not work. I havent not yet tried the ant suggestion.

            Some more background on this; the project was originally created with JBT 3.0.0 CR1/Eclipse 3.4.1 and was imported as a project into the current environment.

            A seam-gen project that I created from scratch in the current environment works fine so I started comparing the various artefacts.

            persistence.xml files are the same, as are the ds- files, as are the hibernate-console.properties and the xxx-launch files.

            Any suggestions where I might start to debug this ? Are there other files that are not visible in the Eclipse views that might be out of alignment ?

            Or... is there another UI to test JPA queries in ?

              the problem is that the console config can't find a META-INF/persistence.xml in the classpath.

              Look for that and check it is in the classpath.

                Thank you very much. That was the problem, but in a more indirect way.

                The .classpath file in the xxx-ejb project had an entry of;



                when I removed the excluding attribute and reopened the Hibernate Configurations view, it worked fine.

                I wonder how the excluding attribute got added though ? I dont hack the .classpath files for Eclipse projects in any way.

                Perhaps consider annonating the error message with a "is META-INF/persistence.xml in the classpath" style hint ?

                Thanks again.

                  The xml snippet got quoted out - what was in it ?

                  With respect to errors, yeah - we could make it better. Could you report it in jira so we don't forget ?

                    .classpath entry;

                      Argh..

                      classpathentry excluding="META-INF/|META-INF/" kind="src" path="ejbModule"/

                      I'll create a JIRA ticket.

                        yeah that exclusion looks really really weird.

                        How was this project created exactly ?

                          It was created using Eclipse 3.4.1/Seam 2.1.1 CR2/JBT 3.0.0 CR1, selecting the New/Seam Web project option and building as an EAR.

                          That generated the four standard projects which worked fine. I then added some jBPM artefacts following the instructions in Chapter 14 of the "Seam In Action" book, but as I said, no direct editing of .classpath files.

                          Had to upgrade to Eclipse 3.4.2 for other reasons so rebuilt the dev. environment with Seam 2.1.1 GA/JBT 3.0.0 CR2 and imported the project into this new env.

                            just weird that the exclusion is there - we don't add it afaik (our tests would fail if we did) hence trying to understand how it got there...

                              I'm using JBDS 1.1.0.GA and experiencing the same problem.

                              My persistence.xml is located here:

                              C:\java\projects\BETS\exploded-archives\BETS.jar\META-INF

                              There are the following persistence-*.xml files here:

                              C:\java\projects\BETS\resources\META-INF\persistence-dev.xml
                              C:\java\projects\BETS\resources\META-INF\persistence-test.xml
                              C:\java\projects\BETS\resources\META-INF\persistence-prod.xml

                              the build.xml picks up the appropriate file depending on configuration.

                              Must I have the ant explode and/or ant deploy target(s) copy the persistence.xml to this location (C:\java\projects\BETS\resources\META-INF) as well in order to avoid this error???

                                So after I copied the persistence.xml from exploded to the correct directory:
