Question

I see that the Flow from Servlet to DAO Layer will be from

Servlet—>Business Delegate—->Service Locator —- >SessionBean –>DAO

If my Servlet is such a way that

public void doGet(HttpServletReq ,HttpServletRes )
{
String uname = request.getParameter("uname");
String password = request.getParameter("password");

EmployeeDTO.setUserName(uname);
EmployeeDTO.setPassword(password);

From Servlet , how can i call the BusinessDelgate ??
Do i need to pass this DTO Object to BusinessDelegate??

}

Yes, you need to pass data transfer object to business layer. Based on given information I can not comment on exactly how to call Business delegate.
