No Persistence provider for EntityManager
Hi,
I am using the following configuration:
JBoss 4.2.2 GA and EJB3/JPA.
Here follows a simple session bean and its remote interface that I've been using:
public interface Monitor {
abstract EntityManager getEm();
abstract void setEm(EntityManager em);
public State create(String id, float in, int r, int b);
public void createState(State s);
public State findById(String id);
}
@Stateless
@Remote(Monitor.class)
public class MonitorBean implements Monitor {
EntityManagerFactory emf;
@PersistenceUnit(name = "StateMonitor")
protected EntityManager em;
public MonitorBean() {
em = emf.createEntityManager();
}
public static final String RemoteJNDIName = MonitorBean.class
.getSimpleName()
+ "/remote";
public static final String LocalJNDIName = MonitorBean.class
.getSimpleName()
+ "/local";
public State create(String id, float in, int r, int b) {
final State state = new State(id, in, r, b, Calendar.getInstance().getTime());
getEm().persist(state);
return state;
}
public void createState(State s) {
em.persist(s);
}
public State findById(String id) {
return em.find(State.class, id);
}
public EntityManager getEm() {
return em;
}
public void setEm(EntityManager em) {
this.em = em;
}
}
As it can be seen the PU named "StateMonitor" is mentioned.
Here follows my persistence.xml file:
<?xml version="1.0" encoding="UTF-8"?> <persistence version="1.0" 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_1_0.xsd"> <persistence-unit name="StateMonitor"> <provider>org.hibernate.ejb.HibernatePersistence</provider> <jta-data-source>java:/OracleDS</jta-data-source> <mapping-file>/META-INF/orm.xml</mapping-file> <properties> <property name="hibernate.show_sql" value="false" /> <property name="hibernate.format_sql" value="false" /> <property name="hibernate.connection.datasource" value="java:/OracleDS" /> <property name="oracle.jdbc.driver.OracleDriver" value="org.hsqldb.jdbcDriver" /> <property name="hibernate.connection.url" value="jdbc:oracle:thin:@<ip.ip.ip.ip>:1521:<DB>" /> <property name="hibernate.connection.username" value="aaaaa" /> <property name="hibernate.connection.password" value="aaaaa" /> <property name="hibernate.dialect" value="org.hibernate.dialect.Oracle10gDialect" /> <property name="hibernate.hbm2ddl.auto" value="create" /> <property name="hibernate.jdbc.use_streams_for_binary" value="false" /> </properties> </persistence-unit> </persistence>
Here how my build .xml looks like:

As it can be seen I've used all the required jars in the classpath.
It seems that the server has no issues deploying the application. The following server log confirms this:

Finally here follows a typical test client:
public class TestClient {

Monitor bean = null;
public void runTest() throws Exception {

Agent agent = new Agent();
bean = (Monitor) ctx.lookup(MonitorBean.RemoteJNDIName);
initEmfAndEm();
bean.getEm().getTransaction().begin();
System.out.println("Monitor Sateless...");
bean.create(agent.getId(), agent.getIn(), agent.getR(), agent.getB());
bean.toString();
bean.getEm().getTransaction().rollback();
} catch (NamingException e) {
e.printStackTrace();
}
}
public void initEmfAndEm() {
emf = Persistence.createEntityManagerFactory("StateMonitor"); em = emf.createEntityManager();
bean.setEm(em);
}
public void closeEmAndEmf() {
bean.getEm().close();
emf.close();
}
public static void main(String[] args) {
try {
TestClient cli = new TestClient();
System.out.println("Created Class...");
cli.runTest();
} catch (Exception e) {
e.printStackTrace();
}
}
}
While running this using ant (build.xml) I am getting the following error:

Requesting all to help please. Do I need any more config/xmls?
-Thanks,
