Rails - Feb 2008 - Reading http request as IO in rails

Hi,
Here''s what i''m trying to do my mobile phone app ( j2me) tries
to
connect to the my rails application.
the j2me app opens a java.io.OutputStream here''s the snippet
	        hc = (HttpConnection) Connector.open(UPDATE_URL,
Connector.READ_WRITE);
	        hc.setRequestMethod(HttpConnection.POST);
	        hc.setRequestProperty("If-Modified-Since",    "29 Oct
1999
19:43:31 GMT");
	        hc.setRequestProperty("User-Agent",  "Profile/MIDP-2.0
Configuration/CLDC-1.2");
	        hc.setRequestProperty("Content-Language", "en-US");
	        out = hc.openOutputStream();

j2me app then just writes data to the output stream(pretty basic
here). so far so good. not a problem here.
And on my rails controller i do the following,

class MainController < ApplicationController
  def read_data
    url    = request.env["REQUEST_URI"]
    method = request.env["REQUEST_METHOD"]
    data   = request.env["RAW_POST_DATA"]

    newf = File.open("MY_DATA", "wb")
    str =  request.body.read
    newf.write(str)
    newf.close
    render :text => "Hello Load #{url}"
  end
end

the problem is the same j2me app works(only changes the url) if i have
a servlet receiving the data, i do request.getInputStream on a servlet
and everything works.
But on rails i get ioexception under j2me app saying couldn''t write to
socket.

Also is request.body.read the correct way to do it. ?
Is this possible in rails or am i making the wrong assumptions here ?
what am i doing wrong, or rather how is it done.

I appreciate any insights that you may have.
