"1. in order to deploy servelts onto a site, is it necessary that we should have a java enabled server.?"
Since a servlet is a Java program that runs on the server, of course your server has to be Java enabled.
"2. on running the startup.bat file. on my tomcat, i get an error message in a dos window such as nvalid ConectionHandler or something . why is this. "
There are lots of reasons for Tomcat not starting. I spent days tracing one that sounds like this. It turned out to be due to a JAR file left over from an earlier installation of JSDK.
I recommend that you temporarily remove the @echo off from the startup.bat and tomcat.bat files so you can see complete error messages.
As a general rule, when asking for help, specify the operating system and JDK version you are using. It sometimes makes a big difference.
