Chapter 18 Examples from Java Servlet
Programming, 2nd Ed
Examples from other chapters:
- Example 18.1: Saying "hello" with JSP
- This shows a simple JSP page that says a personalized Hello
using the predefined request and out variables.
- Example 18.3: Saying "hello" using a JSP declaration
- This shows a JSP page that uses a declaration to define the
getName() method and an expression to print it.
- Example 18.4 and 18.5: Born to be bad
- This shows a JSP page that uses several directives. First it
sets the page directive session attribute to false because the
page doesnt use the session object and theres no need
for the server to create a session needlessly. Then it sets the
errorPage attribute to /errorTaker.jsp so if
the page throws an uncaught exception the errorTaker.jsp
page will handle the display of the error message. The body of
the page throws an exception to trigger the errorPage
- Example 18.6 and 18.7: Saying "hello" using a JavaBean
- This example demonstrates the use of a JavaBeans component with
a JSP page; it says Hello with the help of a HelloBean.
- Example 18.8 to 18.11: A tool application using beans
- This example shows how to use beans to write the tool view application
shown in previous chapters. There's a bean embedded into the JSP
page that gives the page access to the tool information and let
the page act as the view onto that data.
- Example 18.12 and 18.13: A tool application using custom
- This shows how to usethe <iterate> and <property>
tags from Apache Struts to simplify the toolview.jsp
page. This also demonstrates the servlet-driven Model 2 architecture
in which a servlet receives the request, adds attributes to the
request object, then dispatches the request to a JSP that acts
like a template.
