Looks like you are using client side code on the server. You need to make sure you have a clear understanding of how you are handling communications. It looks to me that you have JSNI is a server class. Remember, anything that has a nitave method cannot be loaded by the server unless that native method is JNI not JSNI. My preferred method of communication is to use Jersey(JAX-RS) for the server-side JSON generation and use the RequestBuilder/OverlayType method for the client side. This is not the only way to do this, this is just the method that I have chosen to use the most modular and open approach. If you are only going to be communicating back and forthe between your own application, why not use GWT's RPC. But if you are set on JSON, I would suggest not writing any client code first, just the server and use your browser to access the webservice and ensure that you are indeed getting the expected JSON, then once you have verified that you can use RequestBuilder to access the same URL and get the JSON as a string at which point you can process it into an overlay type and use it within GWT.
