wats the difference between servlets n normal java applications

hi,
i am learning java n havenot touched servlets in detail yet. i want to know how to use servlets n jdbc together? i have worked a bit with msaccess n jdbc-odbc driver n its not working, specially when it comes to writin soemthign to the database. someone advised me to use some other database. and i only have the choice of msSQL server, which i know nuts bout.
anyway my question is that, i can develop an application using SQLserver, then how to convert it into a servlet, or somehow call taht application from a servlet which then shows the results back to the user. confusing? well i dont know how else to put it

, thanx in advance to all the java gurus and novices like me around

I'd start here:

hi,
if u have some idea of CGI programming u could better understand the concept of servlets easily .... but still its not a tough one...... servlets is basically to handle the requests sent by the user on the internet..... if u click on a button by filling a form on the internet .... that request is sent to a servlet which is running on the server ....and processes ur request and send the response back to u ..(in gist). the servlet code is just as normal java code only..... and u can connect to any database as u do to connect using the normal applications.....
thats how the things are ... u just need to go thru an faq on servlets .. u will be comfortable in servlets in no time
thanks
vijay
