You can have a variable called action in your action form. You can set that variable as view or edit. Now for the first time, the action can be view. You lookup for the customer. If you find, you display. If you dont find, (check this with some <c:if> tag ) you display a text field and a ADD CUSTOMER button. You enter the customer name, and click the add button. Again it takes you to the same action class. This action class extends the LookupDispatchAction class. You have different methods for different buttons in that class.(lookup,add etc.). You need only one jsp, one action form and one action class that extends from the LookupDispatchAction class. HTH
