    There is no default persistence unit in this deployment - Il

    David Jitendranath Novice

      I get the following exception when my JBoss server starts up.
      java.lang.RuntimeException: Illegal @PersistenceUnit on private javax.persistence.EntityManager gov.usbr.data.cdw.BurdenRateHome.entityManager :There is no default persistence unit in this deployment.
      at org.jboss.injection.PersistenceContextHandler.handleFieldAnnotations(PersistenceContextHandler.java:182)

      Here's my persistence.xml file. Is there any idea what I'm missing?

      <persistence xmlns="http://java.sun.com/xml/ns/persistence"
      xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
      xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd"
      version="1.0">
      <persistence-unit name="integrations">
      <jta-data-source>java:/cdwDB</jta-data-source>




      </persistence-unit>

            I also have the below two properties set but they dont seem to display in this forum when I copy paste the persistence.xml

            "hibernate.dialect" value="org.hibernate.dialect.HSQLDialect"/>
            "hibernate.hbm2ddl.auto" value="create-drop"/>

              When posting XML text, please use the "code" tag. You can do this by selecting the text and clicking the Code button that appears above the editor window. Also, use the Preview button to ensure the formatting before clicking Submit.

              As for your question, how are your entity beans packaged, and where is the persistence.xml file located? Be specific!

                I reverse engineered and generated hibernate pojos and Session EJB dao code. They are packaged in my ear. My persistence.xml is in the MET-INF folder in the ear file.

                Here's my persistence.xml

                <persistence xmlns="http://java.sun.com/xml/ns/persistence"

                  I assume you mean "META-INF"?

                  For reference:

                  "EJB 3.0 Persistence Specification 6.2.2" wrote:
                  When referencing a persistence unit using the unitName annotation element or persis-
                  tence-unit-name deployment descriptor element, the visibility scope of the persistence unit is determined by its point of definition. A persistence unit that is defined at the level of an EJB-JAR, WAR, or application client jar is scoped to that EJB-JAR, WAR, or application jar respectively and is visible to
                  the components defined in that jar or war. A persistence unit that is defined at the level of the EAR is generally visible to all components in the application.


                  And what about the packaging within your EAR? Are the modules all listed in the manifest META-INF/application.xml?

                  jar -tvf nameOfYourEar.ear


                  If you can provide an isolated (failing) test case w/ this issue, we can open a JIRA and attach the EAR.

                      Might wanna change your packaging as to not bring in your SVN meta into the EAR. ;)

                      Sure, let's open a JIRA and attach your EAR. I'll have a look to see if it's something I'm missing from this post, or a real issue.

                        In the meantime, move the persistence.xml to the META-INF folder of your EJB jar instead of keeping it in the META-INF of the EAR. http://docs.jboss.org/ejb3/app-server/reference/build/reference/en/html/entityconfig.html

                          Thanks Everyone.
                          Thanks jaikiran! it worked when i moved the persistence.xml to the META-INF within the EJB jar.

                          I also found with my existing file structure with the persistence.xml at the top level META-INF in the ear file. It works if I add the unitName to the
                          @PersistenceContext annotation.
                          eg:
                          @PersistenceContext(unitName=UNIT_NAME)

                            I also found that with my current structure of having persistence.xml at the top level META-INF within the ear, it works when I have the unitName for the @PersistenceContext annotation.

                            Eg:

                              It can't be closed if all we've done is identified a workaround. ;)

                              First we need a test for @PersistenceContent w/ no unitName placed at the root of an EAR, checking that the default PU can be resolved.
