[jboss-user] [Persistence, JBoss/CMP, Hibernate, Database] - Annotations inside the HAR

[arres]

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
