Here's my scenario: My web host, which I have telnet and ftp access to but my permissions are limited, has Java installed (including javac, etc) but does not have a servlet engine running. I've heard of people being able to install their own servlet engines on virtual hosts remotely, but I have no clue how to do this.
Could someone point me in the right direction in terms of a) where can I get the appropriate servlet engine, and b) how would I go about installing it on the remote server?
