    EJB Persistence with JBoss 6 v2

    dobbo314 Mar 6, 2011 7:00 AM

      JBoss 6.0.0 Final installed and configured to use MySQL as it's backend database.  Well it seams to work.

       

      Had trouble deploying a simple EJB so I stripped things down to the minimum I could.  The EJB JAR file as almost nothing in it:

           0 Sun Mar 06 10:49:58 GMT 2011 META-INF/
   106 Sun Mar 06 10:49:56 GMT 2011 META-INF/MANIFEST.MF
  1038 Sun Mar 06 10:34:42 GMT 2011 META-INF/persistence.xml
     0 Sun Mar 06 10:48:48 GMT 2011 org/
     0 Sun Mar 06 10:48:48 GMT 2011 org/dobbo/
     0 Sun Mar 06 10:48:48 GMT 2011 org/dobbo/stadia/
     0 Sun Mar 06 10:48:48 GMT 2011 org/dobbo/stadia/data/
  1482 Sun Mar 06 10:48:48 GMT 2011 org/dobbo/stadia/data/Name.class

       

      Here is the important part of the EJB which is a test case for how I wish to develop my idea:

      @Entity
@Inheritance(strategy=InheritanceType.SINGLE_TABLE)
@Table(name="sName")
public class Name
    implements Serializable {

    private UUID theUUID = null;

    private String theName = null;

    public UUID getUUID() {
        return theUUID;
    }

    public void setUUID(UUID newUUID) {
        theUUID = newUUID;}

    @Id
    @Column(name="ident", length=36)
    public String getIdentity() {
        return getUUID().toString();
    }

    public void setUUID(String newUUID) {
        setUUID(UUID.fromString(newUUID));
    }

    @Column(name="name", length=50)
    public final String getName() {
        return theName;
    }

    public void setName(String newName) {
        theName = newName;
    }
}

      And the persistance.xml file that was included in the JAR:

       

       

      q         java:/stadiaDS      org.hibernate.ejb.HibernatePersistence 

      false

      So my questions:

       

      What have I done wrong, not done, missed?

       

      Where is there a really good (i.e. simple) guide to hybernation in JBoss 6?

       

      Many thanks for your help

          Is the posted persistence.xml correct, it is no real xml.

           

          The exception is about incorrect persistence.xml, you should check it or attach the file.

            Sorry, didn't see that the persistence file got messed up, it should have read like this:

             

            <?xml version="1.0" encoding="UTF-8"?>
<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_2_0.xsd"
             version="2.0">
   <persistence-unit name="stadiaDB" transaction-type="JTA">
      <jta-data-source>java:/stadiaDS</jta-data-source>
      <provider>org.hibernate.ejb.HibernatePersistence</provider>

      <exclude-unlisted-classes>false</exclude-unlisted-classes>

      <properties>
        <property name="hibernate.dialect" value="org.hibernate.dialect.MySQLInnoDialect"/>
        <property name="hibernate.hbm2ddl.auto" value="update"/>
        <property name="hibernate.show_sql" value="true"/>
        <property name="hibernate.format_sql" value="true"/>
        <property name="hibernate.transaction.manager_lookup_class" value="org.hibernate.transaction.JBossTransactionManagerLook
up"/>
      </properties>

   </persistence-unit>
</persistence>

            My goal here is for the EJBs to get stored in the MySQL - any settings that work will do.

             

            Once again thanks for your help

              The same error occour if you use a XML editor with validation.

              If I move the <provider> one line up (change posistion of jta-data-source and provider) the xml become valid.

              Check this!

                Thanks Wolf-Dieter Fink.

                That has fixed the problem.  I hadn't thought that although Emacs saw the XML as valid the DTD might have an order to the tags. 

                 

                I also had a problem with the MySQLInnoDialect not working because of a typo and I should have been using "MySQL5InnoDBDialect".

                 

                Just for anyone coming a long afterwards there is also two problems with the EJB file:

                 

                1). The setUUID(String newUUID) should, of course, be called "setIdentity(String new UUID)" or the parsing of the EJB will fail because hybernate will fail as it can't find a setter for the key.

                 

                2). The getUUID() method needs to be marked as "@Transient" so that hybernate doesn't try to map it to a database object.

                 

                But with these three little change my test EJB gets deployed and the table created in the database.  I'm now a happy bunny.

                 

                Many thanks
