My jar file name is TestEJB.jar
It has an entity class Cabin
package com.titan.domain;
import javax.persistence.*;
@Entity
@Table(name="CABIN")
public class Cabin implements java.io.Serializable{
private int id;
private
String name;
private int deckLevel;
private int shipId;
private int bedCount;
@Id
@Column(name="ID")
public int getId( ) { return id; }
public void setId(int pk) { id = pk; }
@Column(name="NAME")
public String getName( ) { return name; }
public void setName(String str) {name = str; }
@Column(name="DECK_LEVEL")
public int getDeckLevel( ) { return deckLevel; }
public void setDeckLevel(int level) { deckLevel = level; }
@Column(name="SHIP_ID")
public int getShipId( ) { return shipId; }
public void setShipId(int sid) { shipId = sid; }
@Column(name="BED_COUNT")
public int getBedCount( ) { return bedCount; }
public void setBedCount(int bed) { bedCount = bed; }
}

Then i have a session bean TravelAgentBean with a remote interface TravelAgentRemote
the remote interface is
package com.titan.travelagent;
import javax.ejb.Remote;
import com.titan.domain.Cabin;
@Remote
public interface TravelAgentRemote {
public void createCabin(Cabin cabin);
public Cabin findCabin(int id);
}
The bean class is
package com.titan.travelagent;
import javax.ejb.Stateless;
import javax.persistence.EntityManager;
import org.jboss.annotation.ejb.RemoteBinding;
import javax.persistence.PersistenceContext;
import com.titan.domain.Cabin;
@Stateless
@RemoteBinding
(jndiBinding="TravelAgentRemote")
public class TravelAgentBean implements TravelAgentRemote{
@PersistenceContext
(unitName="TestEJB")
private EntityManager manager;
public void createCabin(Cabin cabin) {
manager.persist(cabin);
}
public Cabin findCabin(int pKey) {
return manager.find(Cabin.class, pKey);
}
}
Then the client application is
import com.titan.travelagent.TravelAgentRemote;
import com.titan.domain.Cabin;
import javax.naming.InitialContext;
import javax.naming.Context;
import javax.naming.NamingException;
import java.util.Properties;
import javax.rmi.PortableRemoteObject;
public class Client {
public static void main(String [] args)
{
try {
Object ref = getInitialContext().lookup("TestEJB/TravelAgentRemote");
TravelAgentRemote dao = (TravelAgentRemote)
PortableRemoteObject.narrow(ref,TravelAgentRemote.class);
Cabin cabin_1 = new Cabin( );
cabin_1.setId(1);
cabin_1.setName("Master Suite");
cabin_1.setDeckLevel(1);
cabin_1.setShipId(1);
cabin_1.setBedCount(3);
dao.createCabin(cabin_1);
Cabin cabin_2 = dao.findCabin(1);
System.out.println(cabin_2.getName( ));
System.out.println(cabin_2.getDeckLevel( ));
System.out.println(cabin_2.getShipId( ));
System.out.println(cabin_2.getBedCount( ));
} catch (javax.naming.NamingException ne)
{
ne.printStackTrace( );
}
}
public static Context getInitialContext( )
throws javax.naming.NamingException {
Properties p = new Properties( );
p.put(Context.INITIAL_CONTEXT_FACTORY,
"org.jnp.interfaces.NamingContextFactory");
p.put(Context.URL_PKG_PREFIXES,
" org.jboss.naming
rg.jnp.interfaces");
p.put(Context.PROVIDER_URL, "jnp://localhost:1099");
return new javax.naming.InitialContext(p);
}
}
I am using
JBoss and geeting an exception
