Java Persistence API - Hibernate - Unable to build EntityManagerFactory

Question

I am having an issue with JPA which I am unable to solve.

Im deploying my webapp on the glassfish 3+ and when the EntityManagerFactory should be build, it always throws an exeption:

javax.persistence.PersistenceException: [PersistenceUnit: lab4] Unable to build EntityManagerFactory

Heres the Stack Trace:

it seems to me that lab4 can't be found, but my persitance.xml should be correct:

<persistence version="2.0" 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">
  <persistence-unit name="lab4" transaction-type="RESOURCE_LOCAL">
    <provider>org.hibernate.ejb.HibernatePersistence</provider>
    <non-jta-data-source>java:comp/env/jdbc/lab4</non-jta-data-source>
    <class>tuwien.big.formel0.picasa.RaceDriver</class>

    <properties>
      <property name="hibernate.dialect" value="org.hibernate.dialect.H2Dialect"/>
      <property name="hibernate.hbm2ddl.auto" value="create-drop"/>
    </properties>
  </persistence-unit>
</persistence>

And here is the Class in which the EntityManager(Factory) is created:

package formel0api;

import javax.faces.bean.ManagedBean;
import javax.faces.bean.ApplicationScoped;
import javax.persistence.EntityManager;
import javax.persistence.EntityManagerFactory;
import javax.persistence.Persistence;

/**
 *
 * @author Jakob
 */
@ManagedBean(name="entity")
@ApplicationScoped
public class EntityM {
    EntityManagerFactory emf;
    EntityManager em;
    /**
     * Creates a new instance of EntityManager
     */
    public EntityM() {
    }

    public void invoke() {
        emf = Persistence.createEntityManagerFactory("lab4");
        em = emf.createEntityManager();
    }
}

context.xml

<?xml version="1.0" encoding="UTF-8"?>
<Context antiJARLocking="true" path="/lab4">
  <Resource auth="Container" driverClassName="org.h2.Driver" initialSize="4" maxActive="100" maxIdle="100" maxWait="10000" minIdle="1" name="jdbc/lab4" password="lab4" type="javax.sql.DataSource" url="jdbc:h2:mem:lab4;DB_CLOSE_ON_EXIT=FALSE " username="lab4"/>
</Context>

web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="3.0" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd">

    <servlet-mapping>
        <servlet-name>Faces Servlet</servlet-name>
        <url-pattern>/faces/*</url-pattern>
    </servlet-mapping>
    <session-config>
        <session-timeout>
            30
        </session-timeout>
    </session-config>
    <welcome-file-list>
        <welcome-file>faces/index.xhtml</welcome-file>
    </welcome-file-list>
    <servlet>
        <servlet-name>H2Console</servlet-name>
        <servlet-class>org.h2.server.web.WebServlet</servlet-class>
        <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>H2Console</servlet-name>
        <url-pattern>/console/*</url-pattern>
    </servlet-mapping>
</web-app>

Invoke is basically called by clicking a submit button in an xhtml file.

Would be really nice if somebody could help me figuring out what the problem could be, since I am pretty already clueless.

The exception tells you that the JNDI name of the datasource is not found.

Check the DB connection settings and the application container settings to ensure that the datasource is up and running and that it is exposed via this jndi name java:comp/env/jdbc/lab4

Thanks for the help, maybe there is an error in my context.xml or web.xml I have added them in the mainthread, maybe you could look over it? – Jakob Abfalter May 26 '13 at 12:54
Usually you define datasource/jndi bindings in the app server admin console. That's the point of making datasource indipendent from the app – WeMakeSoftware May 26 '13 at 14:30

Yes, have a look at your JNDI name and its data source. Make sure that the name is actually java:comp/env/jdbc/lab4 The exception down is due to that JNDI lookup not being found or being incorrect.
