Hi

i have two jsp

one.jsp
two.jsp

From "one.jsp" i invoke "two.jsp" by calling

two.jsp?value1=20&value2=100

I read the request parameters value1 and value2 in my two.jsp and print it

But in my Browser URL i get only http://localhost:8080/examples/two.jsp?

and not http://localhost:8080/examples/two.jsp?value1=20&value2=100. Why?

=================
one.jsp
<html>
<form name="navigate">
<table>
<tr>
<td on Click="move()"> 1
</td>
<tr>
</table>
</form>
<script>
function move()
{
document.navigate.action="/examples/two.jsp?value1=20&value2=80"
document.navigate.submit();
}
</script>
</html>
===================

two.jsp
<%
out.println(request.getParameter("value1"));
out.println(request.getParameter("value2"));
%>

===================

Hi,
Default form submit method is GET.When one submits the form, form controls are passed as name-value pairs in the URL and any parameters which are included in the url are ignored.
To make it work, just add method="post" in the form tag and you can see value1 and value2 being passed in the url when you invoke any other jsp.
Alternatively, you can also use value1 and value2 as hidden fields and make the request.

I thought in POST, all ur request parameters will not be seen in URL

will this work?
in first jsp i set <hidden name='value1' value='20'> and in second jsp i read it as request.getParameter('value1')>

Srivatsan,
You are correct that POST parameters are not passed or seen in the URL. Also, I recall GET being the default. You might try making the method=get explicit to see if that helps.

Alternatively, you could try the POST as you suggested. Note that the syntax for a hidden field is:
<input type="hidden" name="name" value="value" >
