    Multiple Persistence Units / EntityManagers In Seam 3

    nathandennis Dec 18, 2012 4:44 PM

      Having a little trouble getting this going. I have two databases. Trying to use seam persistence and the documentation is shall we say... incomplete. Ive been doing this for years in seam 2.

       

      Here is what i have and what is happening.

       

       

      public class EntityManagerProducer {
       
       
          @ExtensionManaged
          @Produces// @HighlineDemo
          @PersistenceUnit(unitName="highlinePU")
          @ConversationScoped
          EntityManagerFactory hemf;
          
          @Produces
          @HighlineDemo
          @PersistenceContext(unitName = "highlinePU")
          private EntityManager hem;
          
          @ExtensionManaged
          @Produces
          @PersistenceUnit(unitName="webcarePU")
          @ConversationScoped
          EntityManagerFactory cemf;
          
          @Produces
          @Webcare
          @PersistenceContext(unitName = "webcarePU")
          private EntityManager ceM;
          
          
          
      }

          apparently i hit cntl-s out of habit..

           

            <persistence-unit name="highlinePU" transaction-type="JTA">

                  <provider>org.hibernate.ejb.HibernatePersistence</provider>

                      <jta-data-source>java:jboss/highlineDatasource</jta-data-source>

                      <class>org.xxx.model.xxx.xxx</class>

                      <exclude-unlisted-classes >true</exclude-unlisted-classes>

                  <properties>

                      <property name="hibernate.dialect" value="org.hibernate.dialect.Oracle10gDialect"/>

                      <property name="hibernate.hbm2ddl.auto" value="validate"/>

                      <property name="hibernate.show_sql" value="false"/>

                      <property name="hibernate.format_sql" value="true"/>

                      <property name="hibernate.default_schema" value="xxxx"/>

                      <property name="jboss.entity.manager.factory.jndi.name" value="java:/hemf"/>

                  </properties>

          </persistence-unit>

          <persistence-unit name="webcarePU" transaction-type="JTA">

              <provider>org.hibernate.ejb.HibernatePersistence</provider>

                  <jta-data-source>java:jboss/coreDatasource</jta-data-source>

                 

                 

                  <exclude-unlisted-classes >true</exclude-unlisted-classes>

              <properties>

                  <property name="hibernate.dialect" value="org.hibernate.dialect.SQLServerDialect"/>

                  <property name="hibernate.hbm2ddl.auto" value="validate"/>

                  <property name="hibernate.show_sql" value="false"/>

                  <property name="hibernate.format_sql" value="true"/>

                  <property name="hibernate.default_schema" value="xxxx"/>

                  <property name="hibernate.default_catalog" value="xxxx"/>

                  <property name="jboss.entity.manager.factory.jndi.name" value="java:/cemf"/>

              </properties>

          </persistence-unit>

           

           

          wanted to inject using something like

          @Inject @HighlineDemo
          private EntityManager hem;

           

           

           

          but instead i get this error

          any light you could shed on this error would be greatly apprishiated. I saw a simular error that had to do with the jboss as 7.1.1.final version and it was suppostly fixed according to jason porter in the 7.1.2.final tag. so i built that version and deployed the app to it and got the same error. this app works find if i remove the second entityManager. Ideas?

            Did you try it like this?: 

             

             

            {code:java}
            public class EntityManagerProducer {
              
              @PersistenceContext(unitName = "highlinePU")
              private EntityManager hem;
                
              @PersistenceContext(unitName = "webcarePU")
              private EntityManager ceM;
             
              @Produces 
              @HighlineDemo 
              public EntityManager getHighlineEntityManager() {
                 return hem;
              }
             
              @Produces 
              @Webcare 
              public EntityManager getWebcareEntityManager() {
                return ceM;
              }
            }
            {code}

              it was my understanding that you had to use @Input to make use of seam persistence. otherwise we are just injecting a regular entityManager.

               

              but this problem persists... no pun intended.
