getting back utf-8 data via xmlrpc call

[Gus Mueller <gu...@mu.org>]

I've got a servlet that I'm using with XmlRpcServer to call a class via
xml-rpc.  I'm sending utf-8 data to it, and that's working fine, but
when I try and get utf data back out, it comes out garbled in the areas
where there were multi-byte chars... I fear I'm doing something wrong.

I've already called XmlRpc.setEncoding("UTF-8"); in my servlet's init
method...

My code looks like this (in doPost):

res.setContentType("text/xml; charset=UTF-8");

byte[] result = xmlrpc.execute(req.getInputStream());
res.setContentLength(result.length);

String xml = new String(result, "utf-8");
System.out.println(xml);  // this prints out correctly, I can see the
utf-8 data just fine from the console

StringBuffer sb = new StringBuffer();
sb.append(xml);

PrintWriter out = res.getWriter();
out.print(xml.toString()); // this doesn't print out correctly.
out.close();

I've tried this with both jetty and tomcat, with the same results.  I'm
running on mac osx 10.2.6, jdk 1.4.1.   I've been debugging with curl,
telnet, and my web browser for a couple of hours now, and I'm about to
go nuts.

The strange thing is, when I print out the data via a doGet() like this:

res.setContentType("text/html; charset=UTF-8");
PrintWriter out = res.getWriter();
out.print(new String(myString.getBytes(), "utf-8"));

everything works perfectly.  Does anyone have any suggestions?

thanks,

I haven't tried that... I might see what that gets me.
What I ended up doing was this:

res.setContentType("text/xml; charset=UTF-8");

byte[] result = xmlrpc.execute(req.getInputStream());
PrintStream out = new PrintStream(res.getOutputStream());
out.println(new String(result, "utf-8"));
out.close();



I however, could not send the content-length because it was generating
incorrect results after the PrintStream was done with it.

//res.setContentLength(result.length);


I'm not 100% sure this is the correct solution, but it seems to work.

I am doing exactly the same thing. It seems that setEncoding only works
correct for sending data. Every xml response I receive which is encoded
by UTF-8 also get garbled.
I solved this problem by setting -Dfile.encoding=UTF8 and now I get
correct results. But this is of course also only a temporary solution.
