Hi all,

I am trying to build a jboss application that uses a hibernate archive (HAR).
But when I am trying to access the DAO inside the HAR I got the exception "Unknown entity".

I build the Entity using Annotations.
Do you know if it is possible to build an HAR with Hibernate-Annotations?

I also read that there should be a jboss-hibernate.deployer directory inside the jboss, but I can't find this directory inside my jboss. So I am a little bit confused. Do you know what I should do here?

I am using the following versions:
- JBoss 4.2.2
- Hibernate 3 shipped with JBoss
- Java 6

My HAR contains these files:
- EntityUser.java
- DAOUser.java
- hibernate-service.xml

EntityUser:

package de.backend.persistence.entity;

import javax.persistence.Entity;
import javax.persistence.Table;
import javax.persistence.Id;
import javax.persistence.Column;
import java.io.Serializable;

@Entity
@Table(name="user")
public class EntityUser
 implements Serializable {

 @Id
 @Column(name="id")
 private Long id;

 @Column(name="login_name")
 private String loginName;

 @Column(name="login_pass")
 private String loginPassword;


 public Long getId() {
 return id;
 }

 public void setId(Long id) {
 this.id = id;
 }

 public String getLoginName() {
 return loginName;
 }

 public void setLoginName(String loginName) {
 this.loginName = loginName;
 }

 public String getLoginPassword() {
 return loginPassword;
 }

 public void setLoginPassword(String loginPassword) {
 this.loginPassword = loginPassword;
 }

}

DAOUser:

package de.backend.persistence.dao;

import org.hibernate.SessionFactory;
import org.hibernate.Session;

import javax.naming.InitialContext;

import de.backend.persistence.entity.EntityUser;


public class DAOUser {

 public void storeUser(EntityUser user)
 throws Exception {
 InitialContext ctx = new InitialContext();
 SessionFactory factory = (SessionFactory)ctx.lookup("java:/hibernate/SessionFactoryBase");
 Session hsession = factory.openSession();
 hsession.beginTransaction();
 hsession.save(user);
 hsession.getTransaction().commit();
 }

}

hibernate-service.xml:

<server>
 <mbean code="org.jboss.hibernate.jmx.Hibernate" name="jboss.har:service=Hibernate">
 <attribute name="DatasourceName">java:/base</attribute>
 <attribute name="Dialect">org.hibernate.dialect.PostgreSQLDialect</attribute>
 <attribute name="DefaultSchema">public</attribute>
 <attribute name="SessionFactoryName">java:/hibernate/SessionFactoryBase</attribute>
 <attribute name="CacheProviderClass">org.hibernate.cache.HashtableCacheProvider</attribute>
 <!--<attribute name="Hbm2ddlAuto">create-drop</attribute>-->
 <attribute name="ShowSqlEnabled">true</attribute>
 </mbean>
</server>

This is the Exception that I get when I am trying to access the DAO:

It would be realy nice if you could tell me if I forgot some configuration or make some mistake in developing.
I am getting despreate because I don't know what I can do anymore.

I am looking forward for any help.
Thanks in advance,
Hal
