Question

I have no idea, how to send some text using HTTPCLIENT (java // apache) library. I need to send parameters by text to server.
Any idea?

Answer 1

Assume you have some-remote-server as your remote server address and some-servlet as your remote servlet which accepts param1, param2 etc.. with its respective values on request. If the remote servlet accept GET call you can use below to send the request;

  HttpClient httpClient = new HttpClient();
  GetMethod getMethod = new GetMethod(); //You could use PostMethod if servlet accept POST

  String request ="http://some-remote-server/some-servlet?param1=value1&param2=value2";
  httpClient.getHttpConnectionManager().getParams().setConnectionTimeout(5000);
  getMethod.setURI(new URI(request, false, null));
  ...

And then recieve the response return from the remote servlet like this;

ObjectInputStream ois = new ObjectInputStream(getMethod.getResponseBodyAsStream());
ois.readObject();
