Hi, i am new to web programming and hit a rock when i tried to create a jsp that will perform a http post to another server, based on values passed down via a servlet.

This doesn't work well with the following error.
According to the TLD or the tag file, attribute value is mandatory for tag out.

Am i using wrong methods to retrieve the values?
I would appreciate any advice. thanks.

<body onload="document.forms[0].submit();">
<form action="<c:out name="${model.redirecturl}"/>" method="post">
   <input type="submit" name="xstr" value="<c:out name="${param1}"/>">
