Unable to execute the cmp using the weblogic

Question

I was trying to execute cmp using weblogic server7.0.
It a simple program,
The remote interface-
import javax.ejb.*;
import java.rmi.RemoteException;
public interface SportTeam extends EJBObject{
public void setOwnerName(String ownerName) throws RemoteException;
public String getOwnerName() throws RemoteException;
public void setFranchiseName(String franchiseName) throws RemoteException;
public String getFranchiseName() throws RemoteException;
}The home interface
import javax.ejb.*;
import java.rmi.RemoteException;
import java.util.Collection;
public interface SportTeamHome extends EJBHome{
SportTeam create(String sport,String nickName)throws RemoteException,CreateException;
SportTeam create(String sport,String nickName,String ownerName,String franchisePlayer)throws RemoteException,CreateException;
SportTeam findByPrimaryKey(SportTeamPK sportTeam) throws RemoteException,FinderException;
Collection findByOwnerName(String ownerName) throws RemoteException,FinderException;
}The bean
import javax.ejb.*;
import javax.naming.*;
import java.rmi.RemoteException;
import java.sql.*;
import java.util.*;
public abstract class SportTeamEJB implements EntityBean{
public SportTeamPK ejbCreate(String sport,String nickName) throws CreateException {
setSport(sport);
setNickName(nickName);
setOwnerName(null);
setFranchiseName(null);
return null;
public void ejbPostCreate(String sport,String nickName){}
public SportTeamPK ejbCreate(String sport,String nickName,String ownerName,String franchiseName) throws CreateException {
setSport(sport);
setNickName(nickName);
setOwnerName(ownerName);
setFranchiseName(franchiseName);
return null;
public void ejbPostCreate(String sport,String nickName,String ownerName,String franchiseName){}
public void ejbLoad(){}
public void ejbStore(){}
public void ejbRemove(){}
public void ejbActivate(){}
public void ejbPassivate(){}
public void setEntityContext(EntityContext ctx){}
public void unsetEntityContext(){}
abstract public String getSport();
abstract public void setSport(String sport);
abstract public String getNickName();
abstract public void setNickName(String nickName);
abstract public String getOwnerName();
abstract public void setOwnerName(String ownerName);
abstract public String getFranchiseName();
abstract public void setFranchiseName(String franchiseName);
}the client side program
import java.rmi.RemoteException;
import javax.ejb.*;
import javax.naming.*;
import javax.rmi.PortableRemoteObject;
import java.util.Properties;
import java.util.Collection;
import java.util.Iterator;
public class TestClient{
public static void main(String[] args){
try{
     Properties prop=new Properties();
     prop.setProperty(Context.INITIAL_CONTEXT_FACTORY,"weblogic.jndi.WLInitialContextFactory");
     prop.setProperty(Context.PROVIDER_URL,"t3://localhost:7001");
     InitialContext initial=new InitialContext(prop);
     Object objref=initial.lookup("CMPSportBean");
     SportTeamHome home=(SportTeamHome)PortableRemoteObject.narrow(objref,SportTeamHome.class);
     System.out.println("Creating a row.");
     home.create("basketball","Kings","Joe Maloof","Jason Williams");
     System.out.println("Looking up by primary key...");
     SportTeam team=home.findByPrimaryKey(new SportTeamPK("basketball","Kings"));
     System.out.println("Current franchise player:");
     System.out.println(team.getFranchiseName());
     System.out.println("Looking by by owner...");
     Collection col=home.findByOwnerName("Joe Maloof");
     if(     0 == col.size()     ){
          System.out.println("Found no such owner");
     }else {
          Iterator iter=col.iterator();
          while(iter.hasNext()){
          Object objref2=iter.next();
          SportTeam teamRef2=(SportTeam) PortableRemoteObject.narrow(objref2,SportTeam.class);
          System.out.println("Owner name:"+ teamRef2.getOwnerName());
team.remove();
}catch(RemoveException re){
     re.printStackTrace();
}catch(NamingException ne){
     ne.printStackTrace();
}catch(CreateException ce){
     ce.printStackTrace();
}catch(FinderException fe){
     fe.printStackTrace();
}catch(RemoteException re){
              re.printStackTrace();
}The primary key class
//package sportBean.cmp;
import java.io.Serializable;
public class SportTeamPK implements Serializable{
public String sport;
public String nickName;
public SportTeamPK(){}
public SportTeamPK(String sport,String nickName){
this.sport =sport;
this.nickName=nickName;
public String getSport(){
return sport;
public String getNickName(){
return nickName;
public int hashCode(){
return (sport+nickName).hashCode();
public boolean equals(Object other){
     if( (other == null) ||! (other instanceof SportTeamPK) ){
        return false;
     SportTeamPK otherPK=(SportTeamPK)other;
     return sport.equals(otherPK.sport) && nickName.equals(otherPK.nickName);
The program has complied successfully .

I tried to put the file into the directory structure.
I kept the class files into the WEB-INF/classess
I could'nt understand whats wrong with it.
Please help me it is urgent, if i could understand it i can proceed further

Answer 1

Hi,
I had the same error as you. I'm agree with arvind_India (previous). You must :
1. Define a correct Connection Pool (warning: deploy it on your managed server).
2. Test your connection Pool on your managed server.
3. Create a DataSource from your connection Pool.
4. Deploy your DataSource on your managed server.
5. Verify the JNDI TREE of your managed server (Now, the JNDI name of your dataSource must appair).
6. Deploy your Entity Bean (the error has disapeared).
