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 <[EMAIL PROTECTED]> 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.
