Run makescratch from the shell. This will create a directory /scratch/your_username which has a lot of temporary storage.
Copy the file jakarta-tomcat-4.1.12-LE-jdk14.tar.gz to your /scratch/your_username directory.
Run gunzip to uncompress the file.
Run /usr/local/gnu/bin/tar xf on the file to unpack it.

setenv JAVA_HOME /l/j2sdk1.4.0
setenv CATALINA_HOME /scratch/your_username/jakarta-tomcat-4.1.12-LE-jdk14

Start your favorite browser and point to http://localhost:8080. If you get the Tomcat home page, you have successfully installed the server.
To get started on your assignment, create an html file in /scratch/your_username/jakarta-tomcat-4.1.12-LE-jdk14/webapps/examples with a link which points to "servlet/Sol". When you click on this link using a browser, the server will try to find a Java class Sol in the directory: /scratch/your_username/jakarta-tomcat-4.1.12-LE-jdk14/webapps/examples/WEB-INF/classes and execute the method doPost or doGet.
Run /scratch/your_username/jakarta-tomcat-4.1.12-LE-jdk14/bin/shutdown.sh to shutdown the server. Please do not leave the server running for extended periods of time when you are not monitoring it.
