When I try to get data from web server,the emulator's http status code is 411

[Defonds]

Hi guys,
I have a problem when I try to get data from web server in my Mobile Java application,the http status code I get is 411,so I get no data to use.
However,the same application works well on Sun Emulator:the http status code is 200,and I get the data from web server.
What's wrong with it?Is there anything else I not set before using the S60 emulator?
My SDK is nS60_jme_sdk_3rd_e_FP1,my WTK is sun_java_wireless_toolkit-2_5_2-ml-windows,my IDE is eclipse-jee-galileo-SR1-win32.

411 is "length required", which suggests you are POSTing data, but there is no content-length. This is unusual, as the implementation usually adds this. You could add it manually, but this is usually unnecessary.

Are you POSTing to the server?

Are you writing data to the HttpConnection's OutputStream?

to Graham,
Thank you for your replying,sir.
Yes,I am posting to the server,this is my Mobile Java code:

            String _url = url = cmnet ? ("http://" + host + path) : ("http://10.0.0.172:80" + path);
            System.out.println("The sending address is:" + url);

            http = (HttpConnection) Connector.open(_url, Connector.READ, true);
            if (cmwap) {
                http.setRequestProperty("X-Online-Host", host);
            }
            http.setRequestMethod(HttpConnection.POST);
            String contentType = http.getHeaderField("Content-Type"); 

But I just want to get some data from the server,so I have not written data to The HttpConnection's OutputStream.
If my Java code is wrong,why its jar app works well on Sun Emulator,it even works well on N97 real handset.
I mean is there anything I forgot to set on the S60 emulator,this makes the http status code 411 problem.

Hi,everyone,
The problem has been solved.
Just set request method from post to get:

            http.setRequestMethod(HttpConnection.GET);
            String contentType = http.getHeaderField("Content-Type"); 

Then the emulator of S60 goes well.
Thank you all.
