EngineServices + Links question

[Vinicius Carvalho <ja...@gmail.com>]

Hello there! I need to use asynchronous invocations on my page, XTile
wouldn't do it, because of the complexity of the XML that I need to
return. So I was thinking in create my own service.
I have two situations, a javascript timer that will poll the server in
a regular basis, and a onclick event that will post modifications
(Yes, it is a chat based app). I already have the whole thing
implemented with jsp-servlets, just porting it :P

I'm just confused on how do I create the urls for my pages? let's say:

public void onMessageSend(IRequestCycle cycle){
//Get parameters, assemble an message and store it on messageQueue
}

public void onMessageRequest(IRequestCycle cycle){
//getMessages from queue and store them on the cycle
}

public class ChatService implements IEngineService{
 public void service(IRequestCycle cycle){
 //convert the object on the cycle into XML, change the response
header and flush it :P
}
}

So, my questions are:

1st: How to build the urls (they are gonna be on a javascript)
2nd: Where to store the values on the cycle? cycle.setParameters?

Best Regards
