trouble with request.setCharacterEncoding('UTF-8')

[Helmut Ackermann <he...@wtnet.de>]

Dear CoCoon Developer,

I like to use Your nice java/xml-framework for my WebApplication

My system is: Microsoft Windows XP
Servlet Container: Tomcat 4.1.30
Cocoon Version: cocoon-2.1.4

I have a jsp-page that creates a html-form everything UTF-8 encoded.
Now I want to read the request parameter (send with method post) UTF-8
encoded, but
it seems that the paramters fetched within the jsp and some helper java
classes
will always use the ISO-8859-1 encoding to transform the request data into
java strings.

Now I tried to set 
'container-encoding' (init-parm in cocoon's web.xml) to UTF-8
and
'form-encoding' (init-parm in cocoon's web.xml) to UTF-8

but it seems to have no effect.
(The tcpmon of the axis group shows that the posted parameter values from
the browser are indead UTF-8 encoded)

In addition before and after calling
'request.setCharacterEncoding("UTF-8");'
the method 'request.getCharacterEncoding();'
always returns 'null' - strange isn't it
The java class behind the request seems to be
'org.apache.cocoon.components.jsp.JSPEngineServletRequest'

Please help me, is there any other parameter, which I have overlooked for
reading UTF-8 endoded form values. Why is it possible that the
CharacterEncoding is null after setting explicitly?

Yours sincerly

Yes, ISO-8859-1 is the default behaviour.

You must not set this, this has to be ISO-8859-1.

This is the correct one to change the behaviour.

I don't know exactly if the access from JSP to the request object 
directly the above configuration has effect or if it is just for Cocoon 
internally. You can test it for example using the RequestGenerator.

Before: No, that's not strange. That's a known behaviour of all recent 
browsers, they don't set the header.

After: Yes, that's strange. Looking at the source [1], last method, you 
see that the encoding is not set in the wrapper. I don't know why it was 
done that way. Maybe because for avoiding wrong settings. I.e. when 
setting only 'form-encoding' correctly it maybe works and with setting 
it via setCharacterEncoding() you might break it again.

No, probably only one to much :)
