Chapter 5

Debugging Servlets and JSPs

This appendix gives guidelines for debugging servlets and JSPs in iPlanet Web

Server 6.0. It includes the following sections:

• Servlet Debugging

• JSP Debugging

• Generating a Stack Trace for Debugging

• Using Forte for Java to Debug Servlets and JSPs

• JPDA Options for Debugging

Debugging servlets and JSPs requires that you edit the

jvm12.conf file as described

in this chapter. For more general information about this file, see Appendix C, “JVM

Configuration.”

Servlet Debugging

If the server has been instructed to use a JDK, you can do remote servlet

debugging. If the server is using the JRE, you need to switch it to using the JDK

before you can do remote debugging. For information on instructing the server to

use the JDK or the JRE, see the section “Configuring JRE/JDK Paths,” on page 39.

Assuming that the server is using the JDK, you can enable remote debugging by

following these steps:

1. Make sure that the server is running in single-process mode. Single-process

mode is the default, but you can check in the file

magnus.conf to make sure

that the

MaxProcs parameter is not set to a value greater than 1. If you do not

see a setting for

MaxProcs in magnus.conf, the default value of 1 is enabled for

it. For more information about single process mode versus multi-process

mode, see the iPlanet Web Server Administrator’s Guide.
