I Also have problem uploading to a server with new HttpClient v.4
I am trying to upload a file same as the example in the httpclient
docs.
but it doesn't work and I get NullPointerException when I execute the
post method:
HttpClient client = new DefaultHttpClient();
post = new HttpPost(myServletAddress);
File file = new File(filepath);
FileEntity entity;
if (filepath.substring(filepath.length()-3, filepath.length
()).equalsIgnoreCase("txt") ||
filepath.substring(filepath.length()-3, filepath.length
()).equalsIgnoreCase("log")) {
entity = new FileEntity(file,"text/plain;
charset=\"UTF-8\"");
}else {
entity = new FileEntity(file,"binary/octet-stream");
}
post.setEntity(entity);
HttpResponse response = httpClient.execute(post);
