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.
