I'm sorry, but I'm not able to get this to work with 1.0.9. I don't have a getServerDispatcher(), where is this? On the context, I have just getDispatcher(), but that doesn't seem to be able to find a resource. For now, I tried creating a client and calling the server, which works, but requires me to know the host and port, which locally I know, but when deployed, I will not know. How to dynamically determine the app's host and port? I think I'm going to try porting over to 1.1 and see if it'll work, but I have a feeling, my request will be rejected and we'll be using 1.0.9 till 1.1 is fully released.

Certainly I quoted the 1.1 wiki docs. Besides that, you'll need to substitute something like "riap://application/conditions" for just "riap://conditions" The host part of the riap: pseudoprotocol is used to say whether the reference should be resolved relative to the context's Component, Application, or (now in trunk) VirtualHost. Note that these are relative to the Context from which you get the dispatcher, so you may not be able to say //application if you are explicitly fetching the Component's context. getContext().getClientDispatcher() is the usual way. In the 1.0 tree, you'd need at least the ability to address the server dispatcher (getServerDispatcher()) to make an internal call of any sort. Most of this internal-call goodness came about as the 1.1 effort was starting up though, so I don't rightly remember what's actually exposed in 1.0.x. It is pretty straightforward to develop your solution with HTTP calls in 1.0 and know you can trivially change them to RIAP calls for efficiency when you update to 1.1. - Rob On Wed, May 14, 2008 at 4:58 PM, Bao,Sam <[EMAIL PROTECTED]> wrote: Do you have any sample code that demonstrates the proper usage of the riap? I'm running 1.0.9 so not all of the methods translate directly over to me, but this is what I'm doing inside of my Check Status Resource: // Create a new Component. Component component = new Component(); // Attach the results application. component.getDefaultHost().attach( "/conditions", ConditionsResource.class); component.getContext().getDispatcher().get( "riap://conditions"); I'm attach condition resource class to the "/conditions" path, and then calling a get on it right?
