URL encoding not properly handled in RWT.getRequest.getParameter()? [message #131360] Tue, 05 May 2009 08:11 Go to next message

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
Andrej

Andrej,

the methods you mention are defined in HttpServletRequest and thus
are part of the servlet-engine. if you suspect the error to be there
you would need to forward the problem report to the servlet-engine
implementor.

On the client-side, all request parameters that are sent by RAP
itself are encoded using the encodeURIComponent().

If this doesn't clarify things, please give an example and/or
describe more exactly what you are doing.

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
Andrej

I still don't understand what you are actually doing. Could you post
some code?

Did you try a different servlet-engine or from within the IDE?

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

Hi,

that looks strange. Have you checked your Tomcat encoding settings? In
the server.xml you can configure the URIEncoding for each connector.
Maybe that helps?

As Rüdiger says, it would be a good start to check if this also happens
with Jetty or another container.

Regards,
Stefan.

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:
http://wiki.eclipse.org/RAP/FAQ#Why_are_there_encoding_issue s_after_deploying_my_RAP_application_as_a_WAR.3F

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

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
