Before running Tomcat on your computer, the JAVA_HOME and CATALINA_HOME
environmental variables must be set correctly.

• If you are sure that you have the JAVA_HOME and CATALINA_HOME environmental
  variables defined correctly, skip directly to Installing the Server Component.
• If you do not currently have the JAVA_HOME and CATALINA_HOME environmental
  variables defined or are unsure about whether they are defined correctly, complete the
  following steps to do that.

For Windows 95, 98, or ME

1. Make a backup of your autoexec.bat file.? (As you may have more than one
   autoexec.bat file on your system, ensure that you are working with the autoexec.bat
   file that is on your main booting device, for example, C:\autoexec.bat.)
2. Using Notepad (or any other plain text editor), edit your autoexec.bat file.
3. At the end of the autoexec.bat file, type set JAVA_HOME=?path? (where ?path? is
   the path to your JVM, e.g., C:\Program Files\Java).
4. On the next line of the file, type set CATALINA_HOME=?path? (where ?path? is the
   path to Tomcat, e.g., C:\Program Files\Apache Tomcat 4.0).
5. Save the autoexec.bat file by selecting File and then Save.
6. Close the editor window.
7. Restart your computer.
8. Complete the steps in Installing the Server Component.
