TextStreamResponse and XML and UTF-8
Hi all,
I am trying to return an rss feed using TextStreamResponse("text/xml",
myfeed);
The problem is the that I can't make TextStreamResponse to show UTF-8 (greek
in my case) characters.
I tried to set the content type in the response of RequestGlobals and also
added a Utf8Filter with no luck
The same feed is displayed fine when I requested through a simple servlet.
I can see the characters in the returned string, and if I save the page
source as an UTF-8 file I can displayed it correctly.
However, I can't make my browser or my GUI to display the xml if I directly
request it using TextStreamResponse.
Dont know if it's related with this post:
http://www.nabble.com/T5-confused-about-Services-and-XmlHttpResponse-tf4160459.html#a11839004
Any advice plz?
Thanks
Thanos

FIX TextStreamResponse
public InputStream getStream() throws IOException {
ContentType ct = new ContentType(_contentType);
String charset = ct.getParameter("charset");
if (StringUtils.isNotBlank(charset)) {
return new ByteArrayInputStream(_text.getBytes(charset));
} else {
return new ByteArrayInputStream(_text.getBytes());
}
}
USE:
return new TextStreamResponse("text/html;charset=UTF-8", writer.toString());

Re: TextStreamResponse and XML and UTF-8
Posted by thanos <at...@gmail.com>.
Yes, forcing the encoding to "UTF-8" inside a ByteArrayInputStream did the
trick.
It works now!
I will soon make some tests to compare the two approaches (Template based
XML vs StreamResponse), since perfomance was the main reason I switched to
Tapestry. Will keep you posted.
Many thanks to all of you guys :)

Re: TextStreamResponse and XML and UTF-8
Posted by Ezra Epstein <ez...@yahoo.com>.
This is another way to do it. Look at the code for TextStreamResponse. Write your own StreamResponse impl that's backed by a ByteArrayInputStream.
(The reason I avoid that approach is (a) you create an InputStream to write a response, so under the covers Tap5 is reading from it and writing to the actual HTTP output stream which means that (b) the performance is a bit degraded and (c) you have to hold the whole reply in memory rather than streaming it back to the client.)
Fernando Padilla <fe...@alum.mit.edu> wrote: Essentially, you gave it a string (UTF16 in memory), and it is being
converted into bytes ( string.getBytes() within TextStreamResponse ).
And the contentType of the response is set also from TextStreamResponse.
I would double check what the string.getBytes() is returning, maybe it's
actually putting out bytes in UTF-8, but the HTTP response assumes it's
not in UTF-8, but ISO-LATIN-1 or somesuch. So you're getting the
correct bytes, but they are being interpreted wrong..
1) you might just have to add the charset to the mimetype..
"text/xml;charset=UTF-8"?
2) If you want your 3rd party library to take over more rendering, then
create StreamResponse object that goes from a byte[] instead of a
String, then you have full control on how that strings gets encoded
(utf-8 charset).
3) Maybe there is a bug/enhancement here and
StreamResponseResultProcessor, and TextStreamResponse should be paying
more attention to the charset of the mimetype.

Re: TextStreamResponse and XML and UTF-8
Posted by thanos <at...@gmail.com>.
I used
boolean beforeRenderTemplate(){
return false;
}
but couldn't skip rendering check
I will currently return xml using a template with the help of Fernando's
patch - TAPESTRY-1600.
This patch allows the generation of xml, from an xml-based description by
fixing the "cutting" of namespaces from tapestry. This way I a can set and
keep UTF-8 encoding.
I would like, however, to have the option to return a complete UTF-8 xml/rss
created from say another library (I am currently using rome), using
TextStreamResponse or Printwriter, so if anyone has a code example that will
actually perform my original request, please post it here.

You can override one of the page render methods (I think onactivate is one of those, but check the Tap5 website) and return false !!!! to tell Tap to skip the other steps of page rendering.

I tried that but I get a mix of xml and html erro String (insteαd of clean

Inside onActivate I obtain a PrintWriter from the injected Response, using
"application/xml; charset=UTF-8"
as content type. I print a small test xml string in printwriter and then I
flush the printwriter.
I return null in onActivate().
Did I do something wrong?

Re: TextStreamResponse and XML and UTF-8
Posted by Ezra Epstein <ez...@yahoo.com>.
If you're just returning an RSS feed you probably don't want any page wrapping, etc. In that case you can:
@Inject
private Response _response;
You can then do things like setting headers and even write directly to the container-provided OutputStream - bypassing the whole TextStreamResponse -- just have your method flsuh() the output stream and return null. This should also give slightly better performance.

Hi all,
I am trying to return an rss feed using TextStreamResponse("text/xml",
myfeed);
The problem is the that I can't make TextStreamResponse to show UTF-8 (greek
in my case) characters.
I tried to set the content type in the response of RequestGlobals and also
added a Utf8Filter with no luck
The same feed is displayed fine when I requested through a simple servlet.
I can see the characters in the returned string, and if I save the page
source as an UTF-8 file I can displayed it correctly.
However, I can't make my browser or my GUI to display the xml if I directly
request it using TextStreamResponse.
Dont know if it's related with this post:

Any advice plz?
Thanks
