As you can see from the sniffed packets, the problem is not in
establishing network connection, but on a higher level: HTTP multipart

Apparently your HTC is able to connect over WIFI to your router and
find a local network laptop running the servlet.
Have you tried having the emulator running on the laptop connect to
localhost using port 10.0.2.2? That could at least establish that the
code works (or not) in that situation. See this link:

192.168.1.100 is my laptop running Tomcat. There is a servlet with
Apache Commons File upload waiting for that multipart file. Works
correctly with uploads from a browser (PC Android).
Thanks,

Is 192.168.1.100 a different computer on the same router?

Hi,
I'm trying to upload a file from Android to Tomcat server using
HttpClient and HttpPost. The android-side code is:
HttpClient client = new DefaultHttpClient();
client.getParams().setParameter(http.socket.timeout, new Integer
(9)); // 90 second
HttpPost httpPost = new
HttpPost(http://192.168.1.100:8080/
mediator/upload);
FileEntity entity = new FileEntity(new
File(filePath), binary/
octet-stream);
httpPost.setEntity(entity);
HttpResponse response =
client.execute(httpPost);
Log.i(TAG, Upload finished. Status: +
response.getStatusLine());
client.getConnectionManager().shutdown();
The result always is HTTP/1.1 400 Bad Request.
I captured the data sent over the network and it looks like:
POST /mediator/upload HTTP/1.1
Content-Length: 8287
Content-Type: binary/octet-stream
Host: 192.168.1.100:8080
Connection: Keep-Alive
User-Agent: Apache-HttpClient/UNAVAILABLE (java 1.4)
Expect: 100-Continue
HTTP/1.1 100 Continue
HTTP/1.1 400 Bad Request
Server: Apache-Coyote/1.1
Content-Type: text/html;charset=UTF-8
Content-Length: 971
Date: Tue, 22 Dec 2009 12:14:47 GMT
Connection: close
I created a simple HTML form for POSTing a file. This works fine from
browser and the data is different:
1) it doesn't use HTTP 100 continue
2) Content-Type: multipart/form-data; boundary=
WebKitFormBoundaryDlIVGYpQG46Q46So
In my client I tried to change the content type to other values than
binary/octet-stream, but when I sniff the traffic, the binary/octet-
stream is still there.
I do this on HTC Here/SDK 1.5.
Thanks,
Radek

I solved the problem. I post my code here for others to have a working
sample:
on the server side I made a simple servlet:
---
---
private void receiveFile(HttpServletRequest req, HttpServletResponse
resp) throws Exception {
Enumeration emns = req.getHeaderNames();
InputStream is = req.getInputStream();
OutputStream os = new
FileOutputStream(req.getHeader(FILENAME_STR));
byte[] buffer = new byte[4096];
int bytesRead;
while ((bytesRead = is.read(buffer)) != -1) {
os.write(buffer, 0, bytesRead);
}
is.close();
os.close();
}
protected void doPost(HttpServletRequest request,HttpServletResponse
response) throws ServletException, IOException {
try {
receiveFile(request,response);
} catch (Exception e) {
System.err.println(ERROR-+e.getMessage());
e.printStackTrace();
}
}
