/**
* Classes used in server-side implementation of remote procedure calls.
*
* The {@link com.google.gwt.user.server.rpc.RemoteServiceServlet RemoteServiceServlet}
* class provides the most convenient implementation
* of server-side GWT RPC. This class can be used in two ways: it can be
* subclassed by servlets that directly implement one or more service
* interfaces, in which case incoming RPC calls will be directed to the
* servlet subclass itself; or it can be overridden to give finer control over
* routing RPC calls within a server framework. (For more details on the
* latter, see the {@link com.google.gwt.user.server.rpc.RemoteServiceServlet#processCall(String) RemoteServiceServlet.processCall(String)} method.)
*
*
*
* Alternatively, GWT RPC can be integrated into an existing framework, by using
* the {@link com.google.gwt.user.server.rpc.RPC RPC} class to perform GWT
* RPC decoding, invocation, and encoding. RemoteServiceServlet need not
* be subclassed at all in this case, though reading its source is advisable.
*
*
*
* Note that the default RemoteServiceServlet implementation never throws
* exceptions to the servlet container. All exceptions that escape the the
* {@link com.google.gwt.user.server.rpc.RemoteServiceServlet#processCall(String) RemoteServiceServlet.processCall(String)}
* method will be caught, logged in the servlet context, and will cause a generic
* failure message to be sent to the GWT client -- with a 500 status code. To
* customize this behavior, override
* {@link com.google.gwt.user.server.rpc.RemoteServiceServlet#doUnexpectedFailure(java.lang.Throwable) RemoteServiceServlet.doUnexpectedFailure(java.lang.Throwable)}.
