The JSP Command-Line Compiler

46 iPlanet Web Server, Enterprise Edition Programmer’s Guide to Servlets • May 2001

Package Names Generated by the JSP

Compiler

When a JSP is compiled, a package is created for it. The package name starts with

_jsps and has each pathname component of the JSP prefixed with an underscore.

For example, the generated package name for

/myjsps/hello.jsp is

_jsps._myjsps.

Because of the implicit package name associated with a generated servlet, you need

an explicit

import directive when you use a bean in a JSP, especially if the bean

doesn’t have a package name. For example:

<%@page import="MyBean" %>

<jsp:useBean id="myBean" class="MyBean" />

Specifying that JSPs Are Precompiled

The jsp-servlet element in the web-apps.xml file allows you to tell iPlanet Web

Server that JSPs in a virtual server are precompiled. Include the following tags

inside a

vs element:

<jsp-servlet enable="true">

<init-param>

<param-name>use-precompiled</param-name>

<param-value>true</param-value>

</init-param>

</jsp-servlet>

For more information about the web-apps.xml file, see Chapter 2, “Web

Applications.”

You do not need to install the JDK to run precompiled JSPs. However, you need the

JDK to develop new JSPs. For information about installing the JDK, see “What

Does the Server Need to Run JSP?,” on page 37.
