Dear all


I am using Hibernate 3.2.6.I have created one small example of creating user using hibernate.I am using the database oracle 10g and JDK1.5.I am trying to deploy my application on the JBOSS 4.0.5-GA.

Here is my Persistence.xml Its inside WebContent/META-INF folder.

<persistence xmlns="http://java.sun.com/xml/ns/persistence"

</properties>
</persistence-unit>

Here is my pojo class for the User entity.

import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.Table;

@Entity
@Table(name="userj")
public class jinesh {
private Integer userId;
private String userName;
private String userPassword;

@Id @GeneratedValue(strategy=GenerationType.AUTO)
@Column(name="user_id")
public Integer getUserId() {
return userId;
}
public void setUserId(Integer userId) {
this.userId = userId;
}

@Column(name="user_name")
public String getUserName() {
return userName;
}
public void setUserName(String userName) {
this.userName = userName;
}

@Column(name="user_password")
public String getUserPassword() {
return userPassword;
}
public void setUserPassword(String userPassword) {
this.userPassword = userPassword;
}


}


Here is the code using which i tried to insert the value inside database.


package com.friends.manager;

import javax.persistence.EntityManager;
import javax.persistence.EntityManagerFactory;
import javax.persistence.EntityTransaction;
import javax.persistence.Persistence;
import javax.persistence.PersistenceContext;

import com.friends.pojo.Login.jinesh;

public class LoginManager {



public static Integer createUser(){
System.out.println("======11111=====");
try{

EntityManagerFactory emf = Persistence.createEntityManagerFactory("friendsnetwork");

EntityManager em;
em = emf.createEntityManager();

EntityTransaction tx = em.getTransaction();
tx.begin();

jinesh loginPojo = new jinesh();

loginPojo.setUserName("Abhi");

loginPojo.setUserPassword("jinesh");

em.persist(loginPojo);

tx.commit();

em.close();

return 0;//Object persisted successfully, hence return 0;
}
catch(Exception e){
System.out.println("=====Error while persisting user=====");
e.printStackTrace();
return -1;//Object not persisted successfully, hence return -1;
}

}
}


When i tried to deploy the above application on jboss and then run the web page.it asks me for the username and password when i submit the
page it gives me the following error stack tarce.It seems that it is not able to find the POJO class.
