Eww Eww even better idea. Add on mod_rewrite and you solution could be as
simple as adding the symlinks like Mike was talking about.
<VirtualHost <IP Address>:80>
ServerName www.tomcat.mydomain.com
ServerAlias *.tomcat.mydomain.com
DocumentRoot /www/tomcat.mydomain.com/html
DirectoryIndex index.html
RewriteEngine On
RewriteCond %(http_host) .
RewriteCond %(http_host) !^www.tomcat.mydomain.com [NC]
RewriteCond %(http_host) ^([^.]+)\.tomcat.mydomain.com [NC]
RewriteRule ^(.*) http://www.tomcat.mydomain.com/%1/ [R=301,L,QSA]
JkMount /* <worker name>
</VirtualHost>
Now if you go to jdoe.tomcat.mydomain.com it will go to the url:
http://www.tomcat.mydomain.com/jdoe
which now could be your symlinked directories and you wouldnt have to change
your config at all after that. Just add and delete symlinks.

If on mod_jk in his case:
JkMount /* <worker name>
would cover all applications regardless of how many apps he had on there.
And in the case of virtual host names you could do a set of wild card hosts
to simplify the process in apache.
In DNS you would have *.tomcat.mydomain.com point to the address of the
server.
In apache you would set the config up like so:
<VirtualHost <IP Address>:80>
ServerName www.tomcat.mydomain.com
ServerAlias *.tomcat.mydomain.com
DocumentRoot /www/tomcat.mydomain.com/html
DirectoryIndex index.html
JkMount /* <worker name>
</VirtualHost>
That would forward all the names from apache to tomcat and then you only
have to deal with tomcat from that point forward. So in tomcat you would
set up a different host for each lab student, instead of machine, if you
have multiple classes. For instance:
jdoe.tomcat.mydomain.com
your server.xml would look something along the lines of what was shown below
for lab01host001.tomcat.mydomain.com but instead lab01host001 would be each
name or whatever scheme you would want to go with.

You might try writing some script they can use that will create a
symlink in the webapps directory to their home directory:
#!/bin/csh
# do whatever needed to write to directory and read or prompt for user
directory
# maybe some other logging or setup ???
cd /usr/local/tomcat/webapps
#create symlink to userdir
ln -s /home/user/dirname dirname
#wait for tomcat to load
sleep 10
exit
Then tomcat will load this as a webapp providing ofcourse that the
directory structure the link is pointing to is a true webapp (containing
WEB-INF, WEB-INF/lib, WEB-INF/classes) directories
Ofcourse, if you are using apache on port 80, and using jk, you will
have to write a script to add the jk-mount as well
