Java HTTP Get/Post/Put/Delete Client with SSL/TLS Certificate Support

I need a class (or more classes) for: 1. Connect to a HTTP SSL Server as own Thread and thread safe and KEEP the communication open. (See Connection Handling:) 1.1 return the state of the connection: stopped connecting connected reconnecting failed 2. The HTTP SSL Server has an own no public TLS Certificate, which must be stored(?) and accept by your client software. The Certificate MUST be stored without User actions. (see file [login to view URL])! 3. Methode sendData: Send with HTTP Get Data 4. Give the return Code and Contect back to my main class (see file Return [login to view URL]) 5. Methode pollEvents: Poll every Second the server with a given HTTP Get command and wait for the answer (could be 20sek) and return to my class. If the communication fail, poll again and return the answer 6. Methode setData: Send with HTTP Post Data 7. Give the return Code and Contect back to my main class (see file Return [login to view URL]) I need the .jar file and the source codes. Connection Handling: The client may use one or multiple TCP connections to communicate with the Server. The Server will follow the HTTP header information from the client, whether a TCP connection shall be closed or kept open after a HTTP response is sent. Server will keep an idle connection alive for 5 seconds before which it is garbage collected. Thus, a client may reuse the TCP connection for multiple HTTP requests and thereby save time and bandwidth as TCP and TLS handshake are only required once. Currently, the Server allows a maximum of 20 connections in parallel. An http session on the Server will be kept open by the Server until it has responded to the request (unless session is closed earlier by the client). A URL to connect to the server will given when the project start.
