Websockets using GWT - Best practice
On the first view on your stack trace, I've seen, that the sources for the backend is missing . Put the sources of each lib/fw in your buildpath, it should change the stack trace, at least -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Websockets using GWT - Best practice
Hi, I'm currently trying to establish a websocket connection in GWT 2.6 and 2.7 using gwt-ws. *My question:* the Google search points me to the gwt-ws project to implement websocket connections. But the code examples there do not work with the jetty version included in GWT 2.6 and 2.7 Is there a best practice to do it know? Any known code examples you can point me to? *More infos about the problem:* The server (coded as shown at Getting Started https://code.google.com/p/gwt-ws/)throws an AbstractMethodExeption. Here is the full StackTrace java.lang.AbstractMethodError: de.csenk.gwt.ws.server.jetty.
