     /**
37 |  |
      * A Screen class for dealing with JSON-RPC requests.  Typically you would
38 |  |
      * extend this class and override the doOutput() method to use TurbineJsonRpc
39 |  |
      * to register the POJOs that will provide the functions you are making
40 |  |
      * available via JSON-RPC.  Use JSONSecureScreen if you need the user to be
41 |  |
      * logged in prior to executing the functions you provide.
42 |  |
      *
43 |  |
      * <p>Here is an example from a superclass:
44 |  |
      * <code>
45 |  |
      * public void doOutput(RunData data) throws Exception
46 |  |
      * {
47 |  |
      *     User user = data.getUser();
48 |  |
      *
49 |  |
      *     MyJsonFunctions myFunctions = new MyJsonFunctions(user.getName());
50 |  |
      *
51 |  |
      *     // Session specific
52 |  |
      *     TurbineJsonRpc.registerObject(data.getSession(), "myFunctions", myFunctions);
53 |  |
      *
54 |  |
      *     // Global
55 |  |
      *     //TurbineJsonRpc.registerObjectGlobal("testGlobal", testObject);
56 |  |
      *
57 |  |
      *     super.doOutput(data);
58 |  |
      * }
59 |  |
      * </code>
60 |  |
      *
61 |  |
      * <p>The class MyFunctions would be something like:
62 |  |
      * <code>
63 |  |
      * public class MyJsonFunctions
64 |  |
      * {
65 |  |
      *     private String getHello(String clientParameter)
66 |  |
      *     {
67 |  |
      *         return "Hello " + clientParameter;
68 |  |
      *     }
69 |  |
      * }
70 |  |
      * </code>
71 |  |
      *
72 |  |
      * <p>This code is derived from the com.metaparadigm.jsonrpc.JSONRPCServlet
