Exception in deployment of ejb ear

[Amit Chauhan]

Hi All ...
I am getting this exception while deploying an ear which contains a call to the entity bean from a session bean , does anybody have an idea where the things are going wrong :

My code goes like this (I have put it in a servlet) ::

  
// set the JNDI Properties
Properties props = new Properties();
     props.setProperty("java.naming.factory.initial", "org.jnp.interfaces.NamingContextFactory");
     props.setProperty("java.naming.factory.url.pkgs", "org.jboss.naming:org.jnp.interfaces");
       props.setProperty("java.naming.provider.url", "localhost:1099");
//       Session mySession= SessionManager.getManager().getSession("comics");
//       ((JNDIConnector)((Session) mySession).getLogin().getConnector()).setLookupType(JNDIConnector.STRING_LOOKUP);
        
       
    
    // invoke the session bean object 
       try {
           Context context = new InitialContext(props);
//        DatabaseLogin login = (DatabaseLogin)mySession.getProject().getLogin();
//        javax.sql.DataSource ds = (javax.sql.DataSource) context.lookup("java:system");
//        System.out.println("Data Source "+ds);
//        JNDIConnector connector = new JNDIConnector(ds);
//        login.setConnector(connector);
           
src.FirstSession myBeabObj = (src.FirstSession) context.lookup("sample123/FirstSessionBean/remote");
myBeabObj.sayHello(Name, Age, Dept);
           PrintWriter pwWriter = response.getWriter();
           pwWriter.println("Before calling Persistence");
            
           
//           new entityCaller().persistEntity(Name, iAge);
           
           
           pwWriter.println("After calling Persistence");
pwWriter.println("new Deployment"+System.currentTimeMillis());
pwWriter.println("You submitted Age"+Name);
pwWriter.println("You submitted Age"+Age);
pwWriter.println("You submitted Age"+Dept);
//pwWriter.println("The Bean returned this value"+myBeabObj.sayHello(Name , Age , Dept ));
System.out.println("Finished Transaction");
} catch (NamingException e) {

System.out.println("Exception Reached");
e.printStackTrace();
}// end of try catch block

In your FirstSessionBean.java, can you show how you declared the EntityManagerFactory called emf ? The problem seems to be there.

Code for the Session Bean

 
package src;
 
import java.util.HashMap;
 
import javax.annotation.Resource;
import javax.ejb.Stateless;
import javax.persistence.EntityManager;
import javax.persistence.EntityManagerFactory;
import javax.persistence.EntityTransaction;
import javax.persistence.Persistence;
import javax.persistence.PersistenceContext;
import javax.persistence.PersistenceContextType;
 

 
import src.FirstSession;
 
public @Stateless class FirstSessionBean implements FirstSession {

@Resource(mappedName="java:/my-ejb-test")
@PersistenceContext(unitName = "testApp")
private EntityManagerFactory emf;
 

@Resource
@PersistenceContext(unitName="testApp" ,type=PersistenceContextType.EXTENDED)
private EntityManager em;
 

public String  sayHello(String Name, String Age , String Dept) {


try {
//begin the transaction
 this.emf = 
      Persistence.createEntityManagerFactory("testApp", 
            new HashMap());
    javax.persistence.EntityManager em = emf.createEntityManager();
    EntityTransaction tx = em.getTransaction();
    tx.begin();
    em.persist(new Employee(Name , Age , Dept));
    tx.commit();
    em.close();
//    // close the transaction 
} catch (RuntimeException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}


return "You have submitted " + Name+ "dd"+ Age+" "+ Dept;


}
}

What is this Resource annotation with the EntityManagerFactory ? You usually declare an EntityManagerFactory the following way :

@PersistenceUnit
private EntityManagerFactory emf;

Hi ,
I changed the code as you said but still it throws up the error message as this :

The code for the bean now looks like this :

   import java.util.HashMap;
 
import javax.annotation.Resource;
import javax.ejb.Stateless;
import javax.persistence.EntityManager;
import javax.persistence.EntityManagerFactory;
import javax.persistence.EntityTransaction;
import javax.persistence.Persistence;
import javax.persistence.PersistenceContext;
import javax.persistence.PersistenceContextType;
import javax.persistence.PersistenceUnit;
 

 
import src.FirstSession;
 
public @Stateless class FirstSessionBean implements FirstSession {

@PersistenceUnit
private EntityManagerFactory emf;
 

@Resource
@PersistenceContext(unitName="testApp" ,type=PersistenceContextType.EXTENDED)
private EntityManager em;
 

public String  sayHello(String Name, String Age , String Dept) {


try {
//begin the transaction
 this.emf = 
      Persistence.createEntityManagerFactory("testApp", 
            new HashMap());
    javax.persistence.EntityManager em = emf.createEntityManager();
    EntityTransaction tx = em.getTransaction();
    tx.begin();
    em.persist(new Employee(Name , Age , Dept));
    tx.commit();
    em.close();
//    // close the transaction 
} catch (RuntimeException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}


return "You have submitted " + Name+ "dd"+ Age+" "+ Dept;


}
}

Hello my friend.
Today I got the same exception with a session bean and could solve it:

When you create a session bean, the IDE sometimes creates a file called "ejb-jar.xml" which declaratively describes these beans and their properties. Since you're using EJB3, annotations allow you to dispense with this XML file. Just remove the file from the following path:
(ejbModule/META-INF/ejb-jar.xml) and the deployment succeeds.

The exception resulted from missing properties in the XML file.

Hope it works for you as it did for me...
