Three
TagSupport
subclasses called CrtShipBean, InsertShip, and DeleteShip
B.
C.
Five JSPs and two Web pages to perform the View component of the application.

2.
In c11, create the following files:
DispShip.jsp
DisplayShip.jsp
ConfirmDel.jsp
DelShip.jsp
ConfirmIns.jsp
EnterShipNum.html
ConfirmDel.html
3.
Copy EnterShipInfoJSP from WebContent/c9 into c11.
4.
In ReviewExWeb/Java Resources/src, create a new folder called c11.
In Java Resources: src/c11, create the following Java classes as
TagSupport
subclasses with
no method stubs:
5.
CrtShipBean InsertShip DeleteShip
6.
Copy Shipment.java and DBAccess.java from ReviewEx/src/c10 to Java Resources/src/c11.
7.
In Web Content/WEB-INF/, create a new folder called tls and in tls a new file called TNT.tld.
8.
In TNT.tld, add the XML to define three tags called crtShipBean, insShip, and delShip and
associate them with the appropriate Java classes.
9.
Add the XML to define a required attribute called
