I have tomcat installed as a standalone on my office computer and can successfully run
servlets when they are installed with the context root under the web-apps directory
with the standard deployment directory configuration.
In Chapter SRV 9. of Sun's Web Application specs they say,
"A servlet container can establish rules for automatic generation of web
applications. For example a ~user/ mapping could be used to map to a web application
based at /home/user/public_html/."
We cannot figure out how to do this. We have tomcat installed on a Linux system
running under Apache. I will be teaching a class using servlets. We would like to have
the students establish their context roots in a public_html directory in their own
account. We have the servlet examples that come with Tomcat setup in my public_html
directory and I placed one of my servlets there and successfully ran it by simply
using the example's uri www.ourdomain:8080/~johnsonk/servlet/ServletClassName with my
servlet's class name instead of one of the examples. The problem is that we cannot get
tomcat to run updated versions of that servlet. Even if I completely delete the
servlet class file it still runs the original version.
In server.xml we have the following entries that we believe are relevant
<Listener className="org.apache.catalina.startup..Userconfig"
directoryName="public_html"
userClass="org.apache.catalina.startup.PasswdUserDatabase"/>
<Context path="/johnsonk" docBase=/home/johnsonk/public_html" debug="0"
reloadable="true"/>
What does the reloadable="true" imply? Are we missing something? What triggers
reloading of a new version of the servlet? In my standalone set up whenever I update
the servlet it immediately runs the new version. Is this because it is in the web-apps
directory? Should the web.xml file differ from the standard setup?
