Java: HTTP libraries

There are different ways how to make a request in Java. Considering Restlet framework:

// Prepare the data for the request
String tp = "http://nb.vse.cz/~svabo/patomat/tp/tp_hasSome2.xml";
String binding = "<pattern_instance><binding
placeholder='?p'>hasDecision</binding><binding
placeholder='?B'>Decision</binding><binding
placeholder='?A'>Paper</binding><binding
placeholder='?C'>Rejection</binding></pattern_instance>";
Representation entity = new StringRepresentation("tp="+tp+"&ontology+"ontology",
                MediaType.TEXT_XML);

// Prepare the request  
ClientResource resource = new
ClientResource("http://owl.vse.cz:8080/ontologyTransformation/detection");  

// Send the HTTP POST request
resource.post(entity);

//Do what you want with a response, e.g.:
resource.getResponseEntity().write(System.out);

Considering Java standard library, an HTTP client, the code snippet would be as follows:

// Prepare the data for the request
NameValuePair[] data = {
  new NameValuePair("tp", "http://nb.vse.cz/~svabo/patomat/tp/tp_hasSome2.xml"),
  new NameValuePair("binding", "<pattern_instance><binding
placeholder='?p'>hasDecision</binding><binding
placeholder='?B'>Decision</binding><binding
placeholder='?A'>Paper</binding><binding
placeholder='?C'>Rejection</binding></pattern_instance>")
};

// Prepare the request
HttpClient client = new HttpClient();

PostMethod post = new
PostMethod("http://owl.vse.cz:8080/ontologyTransformation/instructions");
post.setRequestBody(data);

// Execute the method.
int statusCode = client.executeMethod(post);

//Do what you want with a response, e.g.:
InputStream in = post.getResponseBodyAsStream();
