hi everyone,

I have written these interfaces and classes. i am deploying my application using wl deployer tool. i have included the home interface, remote interface , primarykey class and the bean interface in the deployer tool. i am selecting the persistance for all the three fields viz name,id,salary.
when i am trying to deploy it gives a error saying
"n EJB Employee, the home interface must define the findByPrimaryKey method."
thanx a lot.....................

here is my code
---------------------
Home interface :::
---------------------------------------------------------
package examples.ejb.basic.containerManaged;

import java.rmi.*;
import javax.ejb.*;

public interface EmployeeHome extends EJBHome
{
Employee create(String id,String name,float salary) throws RemoteException,CreateException;
   public Employee findByPrimaryKey(EmployeePK pk) throws RemoteException,FinderException;
}
------------------------------------------------------------Remote interface
----------------------------------------------------------

package examples.ejb.basic.containerManaged;

import java.rmi.*;
import javax.ejb.*;

public interface Employee extends EJBObject
{
float getSalary() throws RemoteException;
void setSalary(float f) throws RemoteException;
}
------------------------------------------------------------
beanclass
-----------------------------------------------------------
package examples.ejb.basic.containerManaged;

import java.rmi.*;
import javax.ejb.*;

public class EmployeeBean implements EntityBean
{
public String id;
public String name;
public float salary;
private EntityContext ec;

public void ejbActivate() {}
public void ejbPassivate() {}
public void ejbRemove() {}
public void ejbLoad(){}
public void ejbStore(){}

public void setEntityContext(EntityContext ec)
{
this.ec = ec;
}
public void unsetEntityContext()
{
this.ec = null;
}

public String ejbCreate(String id,String name,float salary)
{
this.id = id;
this.name = name;
this.salary = salary;
return null;
}
public void ejbPostCreate(String id,String name,float salary)
{
}

public float getSalary()
{
return this.salary;
}
public void setSalary(float f)
{
this.salary = f;
}

public boolean isModified()
{
return true;
}
}
------------------------------------------------------------primarykey class
----------------------------------------------------------
package examples.ejb.basic.containerManaged;

import java.io.Serializable;

public class EmployeePK implements java.io.Serializable
{
public String Employeeid;

public EmployeePK(String Employeeid)
{
this.Employeeid = Employeeid;
}

public EmployeePK()
{
}

public String toString()
{
return Employeeid.toString();
}

}
------------------------------------------------------------

Change yr EmployeePK.java

replace public string EmployeeId to public string id;

Rinku

hi,

i have changed it, it does not work....

can i do it without a primary key class............

thanks

Hi Mahadevan,

Please make the following changes in u'r code:

In the EmployeeBean make the ejbCreate method to return PrimaryKey.

Code u'r PrimaryKey as follows:

public class EmployeePK implements java.io.Serializable
{
public String id;


   //public int id;

    public int hashCode( )
    {
        return Integer.parseInt(id);
    }

    public boolean equals(Object obj)
    {
        if(obj instanceof EmployeePK)
        {
            return (id == ((EmployeePK)obj).id);
        }
        return false;
    }

}

Hope this will do..

Regards
Saran
