Whenever you add a Class to your Application, JBuilder will automatically update it.

13. Select the above NumBerspage subpage in the document window, modify the code:

will:

<% @ Page ErrorPage = "NumBerspage_ERROR.JSP"%>

Replace with:

<% @ page errorpage = "numberspage_error.jsp" import = "java.util.calendar"%>]

JBuilder Generated JSP

The time is <% = Calendar.getInstance (). GetTime ()%>

ENTER NUMBERS:

will

Form method = "post"

Replace with:

Form action = "controller" method = "post"

will:

Replace with:

First Number:

INT Num2 = Integer.Parseint (Request.getParameter ("NUM2"));

Int results = Num1 Num2;

will

Out.println ("

The servlet HAS Received A Post. This is the reply. "); replacement to:

Out.println ("

" Num1 " " Num2 "=" Result "");

12. Select Project / Rebuild "Controller.java" on the menu bar, or select Controller.java directly in the engineering window to select Rebuild to execute. If there is no compilation error, you will be able to see the information of Build success in the information window below DIE.

You can now run this Web Application now. If you can see the correct result, then it is done.
