To extend your knowledge of XML-RPC, code a response to the following activities:

  • The Advogato website offers an XML-RPC server at XMLRPC that has a test.square method that returns the square of a specified number. Write an app that takes user input, calls this method, and displays the result.
  • Write an XML-RPC server app that mimics Advogato, taking the test.square call and returning the square of the number.
