  /* server_getInfo_callback is invoked when dim needs the data for a service.
   * The data is obtained by calling the encodeData method of the DataEncoder
   * interface which returns us a Memory object. Next we extract the data address
   * and size from the returned Memory object.
   *
   * Alternative:
   * I call the following class method: Server.sendMeTheData(theDataEncoder)
   * This method is implemented as
   * sendMeTheData(DataEncoder theDataEncoder)
   * {
   *   Memory theData = theDataEncoder.encodeData();
   *   Server.setDataReference(Memory.dataAddress, Memory.DataSize);
   * }
   * The method setDataReference(int dataAddress, int dataSize) is implemented
   * as a native method and receives directly the data which one can store in
   * a global variable.
   * More complicated, not convinced that it would be more efficient.
