Enabling JSPs

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

Enabling JSPs

To enable JSPs, follow these steps:

1. Enable servlets. Select the Java tab in the Server manager, then select the

Enable/Disable Servlets/JSP tab. Check the Enable Java Globally box to enable

servlets for the entire server. Check the Enable Java for Class box to enable

servlets for a single virtual server class. You cannot enable servlets for a class

unless Java is globally enabled. By default, Java is globally enabled and

enabled for each virtual server class.

2. Include the jsp-servlet element with enable="true" in the web-apps.xml

file. For more information about the

web-apps.xml file, see Chapter 2, “Web

Applications.”

3. Add tools.jar to the JVM classpath. For more information, see Appendix C,

“JVM Configuration.”

Making JSPs Available to Clients

You can make JSPs accessible to clients in one of these two ways:

• Include the JSPs in web applications and deploy those web applications. How

to do this is described in Chapter 2, “Web Applications.”

• Configure the JSPs in the default virtual server. This is provided for backward

compatibility with iPlanet Web Server 4.x. How to do this is described in

Chapter 8, “Legacy Servlet and JSP Configuration.”

Deleting Cache Version Files

The server uses the following directory to cache information for JavaServer Pages

(JSP):

server_root/https-server_id/ClassCache/virtual_server_id/webapp_uri/

You can change the location of the JSP class cache using the scratchdir

initialization parameter of the

jsp-servlet element in the web-apps.xml file. For

more information, see “Other JSP Initialization Parameters,” on page 47.

When the server serves a JSP page, it creates a

.java and a .class file associated

with the JSP and stores them in the JSP class cache under the

ClassCache directory.
