Migration from jserv and servlet spec 2.0 IS NOT EASY!!! (unless you
have 2 servlets and one html page). So you cannot do it quick.
If you have disk space, you can just COPY all stuff you have
to new directories, and install apache and tomcat to run on other
ports that what you use now (probably 80(http), 443(https), 8007(jserv).
Just install latest greatest 1.3.20 apache, change in httpd.conf
the 443 to 9443, 80 9080, and use 9007 for ajp12 (and 9008 for ajp13).
Then you will test everything, and when things work, you will just
kill your new setup, change your config files to standard ports,
kill the previous install of apache/JServ and start the new setup.
And with a bit of luck your downtown will be 30 seconds or less.
