Plz reply asap.

might be the class SQLServerDriver.class missed in
sqlserver.jar ...

you download jar which containing above class...

sometimes you downloaded lower version of jar..

so i recommend you to download latest version and add it class path and check it..

and reply back..

download this:
http://dev.mysql.com/downloads/connector/j/

move the jar in to where the compilation directory is or if your using netbeans right click on the open project go t libraries click add jar/folder and there you go

hope that helped

Helpful if you work with MySQL, but not in case of jayaj who is using ms sql server 2005. READ CAREFULLY NEXT TIME!
