Hi
i think URL encoding is not properly handled in
RWT.getRequest.getParameter() / getParameterMap().
Example:
Parameter-Value: Syst%E8me%20de%20peintures%20de%20fa%E7ades (without
encoding: Système de peintures de façades)
Return-Value of RWT.getRequest.getParaemter(): Syst\ufffdme de peintures de
fa\ufffdades
Any suggetions for a workaround?
Thanks

what i'am trying to say is that special characters like é, è, à and the

when fetched with RWT.getRequest().getParameter(). And i do not have any
clue why.
I believe that i did encode the characters correctly in the URL (i.E. è as
%E8).
we are running tomcat 6.0.18 on a Linux box. I can hardly imagine that it
has to do with the servlet-engine (tomcat).
Maybe you have a suggestion where to start looking at.
Thanks

Hi Rüdiger
You can go on "www.kabe-farben.ch", then on "Baufarben / Putze".
In the left menu click on "Produkte".
Then Click on [FR] so the page changes to french.
All links are references to an RAP-Application. As you can see there are
special characters that must be encoded (the same as the text on the
web-page).
Such encoded characters will all be returned with unicode \ufffd by
RWT.getRequest().getParameter in the RAP-Application.
So we had to set placeholders like /e1, /e2 and the like so we are able to
translate back in the RAP-Application
Thanks

Andrej,
I still can't see any wrong encodings. All french special characters
appear as they should.
Anyway, did you make sure that encodings are handled correctly while
building? See here for example:

I try to explain otherwise:
Suppose you call an RAP Class named RapMain implementing IEntryPoint with
something like http://web-site.com?param1=<value> and <value> includes
correctly URI-encoded special characters.
In RapMain you code "String x=RWT.getRequest().getParameter(param1);".
In x, all special characters are represented by \ufffd.
That is the situation we are facing.
Thanks

Andrej,
this took quite a while, but now I understand you. But unfortunately
I don't know much about this topic.
The HttpServletRequest is implemented by the servlet container. I
would suggest to post this question on the Tomcat or Jetty
newsgroup: Maybe there is someone that can help.
In case there is a solution to this, please share it here.
Thanks
Rüdiger
