Hi,
change Form1.jsp like this....
<%@ page language="java"%>
<HTML><HEAD><TITLE>Form1</TITLE>
<script language="JavaScript">
function submitInfo() {
document.frm1.method="post";
document.frm1.plantId.value = 100;
document.frm1.plantName.value = "Wxyz";
document.frm1.action = "Form2.jsp";
document.frm1.submit();
return;
}
</script></HEAD>
<BODY><CENTER><H4> Test </H4> <BR><BR>
<%! int maxId=50;
String path="Form2.jsp?plantId=" + maxId +
"&plantName=wxyz";
%>
<FORM name="frm1">
<!-- <Input type="text" name="plantId">
<Input type="text" name="plantName"> <BR><BR><BR> -->
<Input type="Button" name="btnSend" value="Submit"
onClick="submitInfo();">
<input type = hidden name = plantId>
<input type= hidden name=plantName>
</CENTER></FORM></BODY>
</HTML>
This code will work.. In your code you have set form method as post and you
are setting the querystring
for post method we can't set the query string. post method uses seperate
socket connection to pass the querystring
and we can't see the query sting in the url box.
thanks,,

Very sorry for the typo.I used the same case while
requesting and while sending.Here is my exact code for
the two forms, Form1.jsp and Form2.jsp.
Form1.jsp :
<%@ page language="java"%>
<HTML><HEAD><TITLE>Form1</TITLE>
<script language="JavaScript">
function submitInfo() {
document.frm1.method="post";
document.frm1.action="Form2.jsp?plantId=100&plantName=wxyz";
document.frm1.submit();
return;
}
</script></HEAD>
<BODY><CENTER><H4> Test </H4> <BR><BR>
<%! int maxId=50;
String path="Form2.jsp?plantId=" + maxId +
"&plantName=wxyz";
%>
<FORM name="frm1">
<!-- <Input type="text" name="plantId">
<Input type="text" name
="plantName"> <BR><BR><BR> -->
<Input type="Button" name="btnSend" value="Submit"
onClick="submitInfo();">
</CENTER></FORM></BODY>
</HTML>
Form2.jsp :
<%@ page language="java"%>
<HTML>
<HEAD>
<TITLE>Plant List</TITLE>
</HEAD>
<BODY>
<CENTER> <H4> Test </H4> <BR><BR>
QueryString : <%= request.getQueryString()%> <BR>
PLantID: <%= request.getParameter("plantId")%>
<BR>
PLantName: <%= request.getParameter("plantName")%>
<BR>
</CENTER>
</BODY>
</HTML>
Thanks,
