Jsp request.getparameter doesn't get querystring values

Question

We have recently deployed our jsp application which was running successfully on ias8i apache jserv into the 8.1.7 JVM and configured the mod_ose on the Oracle HTTP server every thing seems to be fine except the following case.
Here we are accepting the userid,password from a jsp and submiting to the same jsp for action on submit we are reading a combination of jsp form feilds and url querystrings strangely we are able to get values only for the form feilds and querystrings return null.
The same peice of code works fine on apache jserv implementation.
Any clues please write to me.
<SCRIPT Language="JavaScript">
function check_password()
document.Login.action ="problem.jsp?tab=YES&nSessionId="+document.Login.sessionid.value+"&nUserId=" + document.Login.userid.value;
document.Login.target = "_top";
document.Login.method = "post";
document.Login.submit();
</SCRIPT>
<%
userid = request.getParameter("userid");
password = request.getParameter("password");
tab = request.getParameter("tab");
%>
<form name="Login" Border="0" TopMargin="0" LeftMargin="0" Marginheight="0" Marginwidth="0">
<table>
<tr>
<td class="FORMHEADERLEFTB"><b> Login</td>
<td class="FORMHEADERLEFT">:</td>
<td><input TYPE="TEXT" NAME="userid" SIZE="25" VALUE="<%=userid%> MAXLENGTH="10"></td>
</tr>
<tr>
<td class="FORMHEADERLEFTB"> Password</td>
<td class="FORMHEADERLEFT">:</td>
<td><input TYPE="password" NAME="password" SIZE="25" VALUE="<%=password%>" MAXLENGTH="10" onChange="check_password()"></td>
</tr>
</table>
<input type="hidden" name="sessionid" value="999999">
</form>
Thanks

How are you retrieving the parameter values? I am able to retrieve parameters successfully using the following simple testcase:
untitled1.jsp:
<form method="post" action="servlet1">
<P>Username:
<input type="text" name="un"/>
</P>
<P>Password:
<input type="text" name="pw"/></P>
<P>
<input type="submit" value="Submit"/>
</P>
</form>
servlet1.java: (copy and paste from doGet() to doPost() method depending on value of form method in untitled1.jsp)
String un = request.getParameter("un").toString();
String pw = request.getParameter("pw").toString();
out.println(un);
out.println(pw);
Please test this and let me know your results and the differences with what you are trying to do.
