hello,
i have been trying to deploy CMP bean. I am getting the error
NoSuchFieldException. I fail to understand the cause of this problem.
my code is like this
Remote interface ----Student
--------------------
import java.rmi.RemoteException;
import javax.ejb.*;
public interface Student extends EJBObject
{
public String getID() throws RemoteException;
//public void setName(String nm) throws RemoteException;
//public String getName()throws RemoteException;
}
Home interface -----studentHome
--------------------------------
import java.rmi.RemoteException;
import javax.ejb.EJBHome;
import javax.ejb.FinderException;
import javax.ejb.CreateException;
import java.util.Enumeration;
public interface studentHome extends EJBHome
{
public Student create(String id) throws CreateException,RemoteException;
//public Student create(String id,String nm)throws CreateException,RemoteException;
public Student findByPrimaryKey(String id) throws FinderException,RemoteException;
//public Enumeration findByName(String nm) throws FinderException;
}
beanclass----studentbean
-------------------------
import Student;
import studentHome;
import javax.ejb.EntityBean;
import java.rmi.RemoteException;
import javax.ejb.CreateException;
import javax.ejb.*;
public class studentbean implements EntityBean
{
EntityContext ctx;
String id;
//String nm;
public void setEntityContext(EntityContext ct)
{
System.out.println("Entity Context Set");
ctx=ct;
}
public void unsetEntityContext()
{
System.out.println("Entity Context UnSet");
ctx=null;
}
public Student ejbCreate(String i) throws CreateException
{
this.id=new String (i);
//nm="";
return null;
}
public void ejbPostCreate(String id)
{
System.out.println("created with the id");
}
/*public Student ejbCreate(String id,String nm) throws CreateException
{
this.id=new String (id);
this.nm=new String(nm);
return null;
}
public void ejbPostCreate(String id,String nm)
{
System.out.println("created with the id and name");
}
public void setName(String nm)
{
this.nm=new String(nm);
}
public String getName()
{
return nm;
}*/
public String getID()
{
return id;
}
public void ejbRemove()
{
System.out.println("remove called");
}
public void ejbStore()
{
System.out.println("store called:");
}
public void ejbLoad()
{
System.out.println("Load called:");
}
public void ejbActivate()
{
System.out.println("Activate called:");

Hi Anima Agrawal,
My previous post was wrong.
I am sorry for that. Plz do not remove that tag.
The problem could be becoz u have not made the field id in bean class as public. Please do that
