This image shows the sequence of events that occurs when you remove benefits from an employee.

• The client sends a request to the Controller servlet
• The Controller calls the getInstance and createActionHandler methods on the ActionHandlerFactory and calls the performAction method on the RemoveBenefitFromEmployee.
• If the benefits parameter is equal to null:
  • RemoveBenefitFromEmployee forwards the request to the removeBenefitFromEmployee JSP.
  • The removeBenefitFromEmployee JSP calls getEmployeeManager on the SessionHelper, getDetails on the Employee entity bean, and getBenefits on the EmployeeModel.
  • Once the information is gathered, the JSP sends the response back to the client.
• If the benefits parameter is not equal to null:
  • RemoveBenefitFromEmployee calls getEmployeeManager on the SessionHelper, getEmployee on the EmployeeManager, and removeBenefits on the Employee entity bean.
  • If successful, RemoveBenefitFromEmployee forwards the request to the success.jsp page, which returns a success message to the client.
