Making Json-Rpc calls from java

I'm writing a java application which runs on the local machine, it needs to interact with another program (also running on the local machine), the other program has a JSON RPC API which is the best way to interact with it. However, in googling around I found a lot of libraries for exposing JSON RPC methods from a java application but nothing good on how to call a remote JSON method. How would I do this?

The two things I'm looking for are:

  1. A way to create new JSON objects to send
  2. A way to connect to the other program and send my response
  3. A way to decode the JSON response
Solution

  • For interacting with JSON text in Java, see JSON in Java. Use this for building JSON request objects and serializing them to text as well as de-serializaing the response from the RPC server.

    Is this over HTTP or a plain TCP connection? If the former, use HTTPClient. If the latter, just open a socket and use its I/O streams.
