See What is Tomcat and how do I install it?

Edit /usr/local/tomcat/conf/server.xml

<Context path="/ptolemyj"
                 docBase="/home/www/java/ptolemy"
                 reloadable="true"
                 crossContext="true">
          <Listener className="org.apache.ajp.tomcat4.config.ApacheConfig"
                    forwardAll="true"
                    noRoot="true"
                    jkDebug="info"
                    append="true"/>
          <Logger className="org.apache.catalina.logger.FileLogger"
                  verbosity="4"
                  prefix="ptolemyj_log."
                  suffix=".txt"
                  timestamp="true"/>
          <Parameter name="appURLBase" value="/ptolemyj" override="true"/>
        </Context>

Edit /usr/local/apache/conf/tomcat-mod_jk.conf and /usr/local/tomcat/conf/auto/mod_jk.conf
```
JkMount /ptolemyj ajp13
JkMount /ptolemyj/* ajp13
```

Edit /usr/local/apache/conf/rewrite.conf:

RewriteCond %{REQUEST_FILENAME} !/ptolemyj/

Restart the website or run

/etc/init.d/apachectl graceful
/etc/init.d/tomcat stop
/etc/init.d/tomcat start

Try https://chesstst.eecs.berkeley.edu:444/ptolemyj

In the Infrax FAQ, Allen wrote:

Your servlet should have a fully-qualified class name like gsrc.foo.blah.MyServlet, and be installed under the root directory of all the website Java classes, which is /home/www/gsrcwww/java/WEB-INF/classes. So, from that directory, it should be gsrc/foo/blah/MyServlet.class.

To deploy your servlet, a <servlet&gt...</servlet> section must be added to /home/www/gsrcwww/java/WEB-INF/web.xml, to map the servlet name of your chosing (to be used in the servlet's URL) to the fully-qualified class name.

Those sections of that file for the GSRC website are maintained under the javapages CVS module. Check out that module with the command,

  cvs -d :ext:gigasource.eecs.berkeley.edu:/home/cvs checkout javapages

Go to the directory, javapages/gsrc/conf and add the new section to the file, web_xml.section, using existing sections as examples. For example, here is the section for the WorkshopRegistration servlet:

    <servlet>

        <servlet-name>
            WorkshopRegistration
        </servlet-name>
        <servlet-class>
            gsrc.workshop.WorkshopRegistrationServlet
        </servlet-class>
    </servlet>

The servlet is accessed by the URL, "http://www.gigascale.org/gsrc/servlet/WorkshopRegistration".

Run make install to install the changes into /home/www/gsrcwww/java/WEB-INF/web.xml.

After installing the servlet class file and the changes to the web.xml file, restart Tomcat to make the servlet available. To do that, do the following as root on gigascale:

# /etc/init.d/tomcat stop
# /etc/init.d/tomcat start

After verifying the the servlet can be invoked from a browser, commit your changes to web_xml.section.
