Title: RE: Request Parameters Getting Lost

I don't know your problem, but how about giving this a try. Here is a jsp I just wrote which works on tomcat 3.1 and displays all the parameters I give it - See if it works - No comments on my bad coding style(s). I placed it in webapps\root\listparm.jsp and then accessed it via http://localhost:8080/listparm.jsp?func=foo&bad=bar&a=b

<%@ page language="java" %>
<HTML>
<HEAD>
<TITLE>List Parameters</TITLE>
</HEAD>
<BODY>
<%

java.util.Enumeration eNames = request.getParameterNames();

while ( eNames.hasMoreElements() )
{
String strName = (String)eNames.nextElement();
%>
<%= strName %> : <%= request.getParameter(strName).toString() %><BR>
<%
}
%>
<BR>Parameters are above.
</BODY>
</HTML>

Thanks for the pointer. We're accessing the JSP with IE 5.5, which has an option to send URLs as UTF-8. I turned this option off, but alas the request parameters are still not there. Any further advice?

Thanks,

Jason Voegele

We've had the same problem dealing with wireless apps & WAP gateways. Our theory is that the request params are being sent in UTF-8 not ascii and Tomcat can't deal with it. We do not have any problems when using JRun or Websphere.

My apologies, we're actually using request.getParameter("page_id"), as well as the getParameterNames and getParameterValues as you've said. I just wrote the wrong method name in my original email.

Given that we are using the proper methods, is there any way to explain this behavior?

Thanks,
Jason Voegele

Actually, the functions are getParameterNames and getParameterValues

Hi Jason,

I use Tomcat 3.1final and in an JSP the implicit object "request". If you
know the name of the parameter use request.getParameter(<name>). Where is
the method "getRequestParameters()" located -- for sure not in
javax.servlet.ServletRequest?

Regards

Stefan
