Subject Re: NULL request params when POSTing data in 2.1...
Date Thu, 21 Aug 2003 00:24:09 GMT

Hi guys,

I haven't solved my problem of getting null request parameters when trying 
to read request params in an action, so...

Does anybody know how GET vs POST request parameters are handled by Tomcat 
and Cocoon?  To reiterate, it *does* work when I try using GET, but I really 
need to use POST (want to pass some files in addition to data; when I tried 
GET I commented out the file input fields).

I'd appreciate your insights into these two methods of transferring data via 
HTTP and how they're handled by the servlet container and by Cocoon.

I'm running:
Tomcat 4.1.12
Cocoon 2.1 (released version from last week)
RedHat Linux 7.2

Thanks for your help,


P.S. This problem only occurs with Cocoon 2.1. I have Cocoon 2.0.4 backed up 
and I tried it again with that and I can always fetch the POSTed request 
parameters just fine in my action.  The code is straightforward:

Request request = ObjectModelHelper.getRequest(objectModel);
String someParam = request.getParameter("param");
