Trouble posting image file from Android app to Java servlet hosted on Tomcat

One feature of an Android app I am working on is to take a picture and upload it via HTTP Post to a Java servlet. I have found a number of examples of how the general process should work, and tried all of them. Currently, the code looks like this:

Client:

String fileName = pathToFile;
DefaultHttpClient httpclient = new DefaultHttpClient();
HttpPost method = new HttpPost(path);
MultipartEntity entity = new MultipartEntity();
FileBody fileBody = new FileBody(new File(fileName));
entity.addPart("file", fileBody);
method.setEntity(entity);

HttpResponse response = httpclient.execute(method);

Server:

List<FileItem> fileItems =
new ServletFileUpload( new DiskFileItemFactory( 1024 * 1024, new File("C:\\tmp" ))).
parseRequest(request);

for ( FileItem item : fileItems ) {
String fieldName = item.getFieldName();

if ( item.isFormField()) { 
    item.getString();
}
else {
    item.getInputStream();
} // File uploaded
}

Right now, I am not worried about what to do with the input stream, because this code fails when we call parseRequest(request) with this error: org.apache.tomcat.util.http.fileupload.MultipartStream$MalformedStreamException: Stream ended unexpectedly

I am a new user of the Apache HttpUpload library. What am I missing here?

Thanks in advance.

Try using the constructor :

    MultipartEntity entity = new MultipartEntity(HttpMultipartMode.BROWSER_COMPATIBLE);

The default is using mode STRICT and this may be the problem.
