Yes all defaults.
Code snippet
m_multiThreadedHttpConnectionManager = new
MultiThreadedHttpConnectionManager();
m_client = new HttpClient(m_multiThreadedHttpConnectionManager);
PostMethod post = new PostMethod(url);
try {
post.setRequestEntity(new
InputStreamRequestEntity(serializeObject(request)));
NameValuePair[] pair = new NameValuePair[1];
pair[0] = new NameValuePair(name, value);
post.setQueryString(pair);
m_client.executeMethod(post);
if (post.getStatusCode() == 200) {
ObjectInputStream responseStream = new
ObjectInputStream(post.getResponseBodyAsStream());
return responseStream.readObject();
}
