    Embedded Alpha 5 can't find persistence.unit

    John Gilbert Apprentice

      I just upgraded from embedded alpha 4 to alpha 5 and the container can't find the persistence unit unless I create a jar first. I didn't have to do this with alpha 4. Here is the output from the simple-tutorial.

      WARN 05-02 17:25:00,921 (BeanSchemaBinding.java:init:227) -You should use the 2.0 version of the Microcontainer xml. xmlns='urn:jboss:bean-deployer:2.0'

      For some reason putting archiveByResource and deployDirs in my ejb3-deployment.xml doesn't seem to work anymore. Any ideas?




      .

          ahhh!
          i see that alpha 5 upgraded the persistence.xml format to spec.
          problem solved!

                I got mine to work..... My error was that my bean mappings in embedded-jboss-beans.xml did not match those in my persistence.xml

                For example:

                ----------embedded-jboss-beans.xml------



                org.hsqldb.jdbcDriver
                jdbc:hsqldb:test/conf/hsqldb/superduper
                sa

                java:/superduperDS
                0
                10
                1000
                100000












                -----------persistence.xml---------------------

                <persistence-unit name="superduper">
                <jta-data-source>java:/superduperDS</jta-data-source>




                </persistence-unit>



                If I call my datasource superduperDS then I need to make sure that bean name for the bootstrap is called superduperDSBootstrap and the bean name for the datasouce is called superduperDS. All this is case sensitive. So make sure your names are consistent and good luck.

                    Thanks very much, dhinojosa.

                    Mine was a classpath problem. It seems that file persistence.xml inside tutorial.jar can never be found & read.

                    I think this is a silly problem, because it's better to deploy persistence.xml along with .jar that contains the beans. I still haven't found the solution.

                    regards

                      Well about the persistence.xml it does have to be in a META-INF folder. So, as far as your classpath goes make sure that within that classpath there is your META-INF folder with the persistence.xml within it.

                        Thanks again, dhinojosa.
                        Persistence.xml was correctly placed in meta-inf inside Tutorial.jar.
                        It was the .jar that was not place on classpath.
                        now it works very well.
                        bye

                          That absolutely solved my problem! Got firebird working. Now I can easily and quickly unit test my ejb3 classes locally

                          :-) Thank you so much!
