[EJB 3.0] - Driver problems with Persistence.XML - jboss-user

Tuesday, 20 November 2007

Hi,
I have a very simple War, which contains a JSP and a pesistence.xml file.
The Persistence.XML defines my persistence unit:

  |    <persistence-unit name="h-source">
  |        <properties>
  |             <property name="hibernate.connection.driver_class"
value="oracle.jdbc.driver.OracleDriver"/>
  |                <property name="hibernate.connection.username"
value="test_garageDB"/>
  |             <property name="hibernate.connection.password"
value="test_garageDB"/>
  |             <property name="hibernate.connection.url"
value="jdbc:oracle:thin:@opc151:1521:ora10g"/>
  |             <property name="hibernate.cache.provider_class"
value="org.hibernate.cache.HashtableCacheProvider"/>
  |        		<property name="hibernate.dialect"
value="org.hibernate.dialect.Oracle9Dialect"/> 
  |        </properties>
  |    </persistence-unit>
  | 
  | 

The JSP creates and excutes a simple query

  | <%@ page info="Test" language="java"
  | import="javax.transaction.*, javax.naming.*, java.sql.*,
com.arjuna.ats.jdbc.TransactionalDriver, java.util.Properties,
  | 		oracle.jdbc.xa.client.OracleXADataSource, javax.sql.*, javax.persistence.*, 
  |     		org.hibernate.ejb.EntityManagerImpl"%>
  | <html>
  | <body>
  | Home is HOME
  | <% 
  |    oracle.jdbc.driver.OracleDriver d = new oracle.jdbc.driver.OracleDriver();
  |    DriverManager.registerDriver(d);
  | 
  | 
  |    EntityManagerFactory emf =
  | 		Persistence.createEntityManagerFactory("h-source");
  |    System.out.println("emf is " + emf);
  |    EntityManager em = emf.createEntityManager();
  |    EntityManagerImpl emImpl = (EntityManagerImpl)em;
  |    Connection con = emImpl.getSession().connection();
  |    System.out.println("Connection is " + con);
  |    System.out.println("em is " + em);
  |    Query q = em.createNativeQuery("insert into TAddress (C, I, CITY) " +
  | 	    			"VALUES (" + 29 + ", " + 333 +
  | 	    	", 'DUBLIN7')");
  |    q.getSingleResult();
  | %>
  | 
  | </body>
  | </html>
  | 

However, I get: 

  | java.sql.SQLException: No suitable driver
  | 	java.sql.DriverManager.getConnection(DriverManager.java:545)
  | 	java.sql.DriverManager.getConnection(DriverManager.java:140)
  | 

I have my driver jar in the lib directory.
I also instantiate it, so I cannot see what I am doing wrong?

Any ideas
