Don't write database connectivity code in a JSP; that's not what JSP's were meant for. Push all that database logic inside a servlet. Use JSP only as a presentation technology.

And BTW, have you hosted your files on the Tomcat server? What is the URL you are using to access your HTML? What kind of error do you get? Aren't the error logs useful?

:S and, this line is missing

pst.executeUpdate();

right ppl?

I wouldn't know. As soon as I see a tag starting a scriptlet I quit reading and give the canned answer to not use Java code in JSP.

#
String userName = "roor";
#
String password = "root";

i think you should take care of Name
check it plase it should be ROOT not ROOR
