passing parameters from jsp to servlets????

i have this program, a jsp passing parameters in servlets. i deploy it in tomcat by creating a war file. i also edited the deployment descriptor. but as i run the program,(the jsp program first and by clicking the submit button, an error message occurred "the page cannot be displayed"). The jsp page and the servlets are all in one folder.
(
/weblink/FlightRequest.jsp
/weblink/web-inf/classes/FlightRequest.java)
the jsp program is:
<html>
<...>
<form action="/FlightRequest" method="post">
<...>
<input type="submit" value="submit">
</form></body></html>
