How to implement Home Method in Entity Bean?

[Gowher Naik]

//home interface
public interface EmployeeHome extends EJBHome{
//other methods
public String getAllEmpNames()throws FinderException,RemoteException;
}
//bean
public String ejbHomeGetAllEmployeeNames()throws FinderException{
 String names=null ;
 Collection c=[B]ejbSelectGetAllEmpNames[/B]();
 Iterator i=c.iterator();
 while(i.hasNext()){
 names=names+i.next();
 }
 return names;
 }
 public abstract Collection ejbSelectGetAllEmpNames()throws FinderException;
 
//Query for ejbSelectGetAllEmpNames SELECT OBJECT(m) FROM Employee m
 
//if Return EJBs Of Type is Remote 
/*then at deploy time it says RemoteException Error processing ejb jar compilation failed*/
 
//if Return EJBs Of Type is none
//then at Genrate sql it throws Error as 
/*Query returning local ejbs must have local interface defined
EJB QL statement SELECT OBJECT(m) FROM Employee m
Method Collection ejbSelectGetAllEmpNames()*/

Above is code for home interface and bean class
in Home i have home method getAllEmpNames
in bean i have ejbHomeGetAllEmployeeNames for getAllEmpNames
ejbHomeGetAllEmployeeNames uses ejbSelectGetAllEmpNames method.

First of all i want to know is i am using correct procedure or there is something missing.
Second why it throws error
