Example JSP Page with Scripting Elements

This section provides a tutorial example JSP page, Hello_Scripting.jsp, with some scripting elements: 1 scriptlet, 2 scripting expressions and 1 scripting declaration.

To verify those JSP page conversion rules, let's write a very simple JSP page with some static data and scripting elements and deploy it on the Apache Tomcat server to see how it will be converted.

1. Write the following JSP page, Hello_Scripting.jsp:

<!-- Hello_Scripting.jsp
   Copyright (c) 2002, HerongYang.com, All Rights Reserved.
<%= greeting() %>
<% out.println("Hello world!"); %>
<%= "-- From JSP" %>
   private String greeting() {
      return "Scripting Elements:";

2. To deploy this JSP page, just copy the file to C:\local\tomcat\webapps\ROOT\Hello_Scripting.jsp.

3. Run a Web browser and enter this URL: http://localhost:8080/Hello_Scripting.jsp. You should see this output on the browser screen:

Scripting Elements:
Hello world!

-- From JSP

The above result shows that:

See the next tutorial to find out where the converted Java source code is located.
