I agree on the issue of extra weight of Tomcat (or any other servlet engine). However, this is a double-edged sword. The servlet engine can avoid some amount of repeated computation by keeping some state in memory, thus bringing down some overheads. I don't know how to do this in mod_perl. For instance, if I create an object instance in a Java servlet, and attach it to a static member somewhere, that object instance just stays alive till the servlet engine comes down. Thus, one servlet can "set a global variable", which a second servlet can access later. I don't know how to do this in mod_perl. When we looked at mod_perl last, I couldn't figure out how to do this. I know you can do global initialisation when the mod_perl system starts up (and this is a huge performance help), but I don't know "how to set global state" in one mod_perl unit, and keep it there for the next invocation to access. > As a matter of personal taste, I would stay away from all things Java > as far as possible ... :) I presume you've read http://www.paulgraham.com/javacover.html and http://www.paulgraham.com/avg.html ... in fact, most of the articles on that site are superb.

Seconded. :) Shuvam PS: Please communicate my warm regards to Phatak and Kavi Arya, since you appear to be in the same school as them.
