^Hello, I want to access a web service with a GWT client. My idea is to implement a web service that could still be used if I change or add a new client.
I see 3 solutions : 1/ GWT RPC 2/ a json web service 3/ GWT edition of restlet My analysis : 1/ GWT RPC : if I change of client, I would have to re write also server side => eliminated 2/ a json web service : possible, restlet on the server side would be perfect, but serialization must be done and on the client side I would have to deal with overlay types. 3/ GWT edition of restlet : hum, very seducing, BUT the condition is that I manage to retrieve json from any other client than GWT. And so far I was not able to do this. It should be possible since it is mentionned in two places in the documentation : - a comment in the restlet wiki : http://wiki.restlet.org/docs_2.0/13-restlet/21-restlet/318-restlet/303-restlet.html - a scheme (4th in the page) : http://wiki.restlet.org/docs_2.0/13-restlet/275-restlet/144-restlet/185-restlet.html => does anyone knows how to retrieve json from a ServerRessource without having to manualy serialize the object ? Hereby what I managed to obtain (it works but the serialization is done by me...) public class OperationServerRessource extends ServerResource implements OperationRessource { private Operation ope; @Override protected void doInit() { super.doInit(); this.ope = new Operation(); // the object to send } @Get public Object retrieve() { return ope; } @Get("json") // is retrieved when on the client side with this request : // (new ClientResource("/restlet/testGwtOperationRessource")).get(MediaType.APPLICATION_JSON) // but I wish I would not have to make the serialization myself... public String retrieveJson() { String st = "{\"key2\":\"value2\", \"key1\":\"value1\"}"; return st; } } thank's Ben ps : a forum instead of a mailing list could be a good way to facilitate the community get bigger (in a forum you can ad nice links, blocs of code, mail triggered when there is a new reply on the post you follow etc ...) That's just a suggestion, there may be some good reasons for keeping a mailing list... ------------------------------------------------------ http://restlet.tigris.org/ds/viewMessage.do?dsForumId=4447&dsMessageId=2649959
