<html>
<body>
<h1 align="center">Beer Selection</h1>
<form method="post" action="SelectBeer.do">
Select Beer Characteristics

tried that didn't work .
dude could you send me
the details of your environment variables. i think they are the source of problems.

Environment variables have nothing to do with this.

The very files you posted work just fine for me. Have you restarted the web app after deploying them?

i am having the same problem. and I've tried restarting the web-app many times. but its still not working

Thanks for your time man!
And yes i have redeployed Again and again

. I shutdown the server ,close the browser and then restart the whole thing.
I have jdk and apache installed am i missing anything else???
Which sw's do you have installed???
