Re: gson module problem
The easiest way to convert between JSON and GWT objects is to use overlay objects. Unfortunately, there is no type checking by doing this, but you get the best performance. Now, if you need to support older versions of IE you will need to include json2.js in your project, but you can use the JSON.parse and JSON.stringify functions to convert between javascript objects and a JSON string. http://code.google.com/p/google-web-toolkit/wiki/OverlayTypes On Jul 7, 10:41 am, Ahmed Shoeib ahmedelsayed.sho...@gmail.com wrote: i need to convert JSON to/From Java Object how to do it ? i don't know how to use this way On Jul 6, 10:35 pm, eggsy84 jimbob...@hotmail.com wrote: Hi all, With the latest versions of GWT you don't have to use any other libraries.

Re: gson module problem
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.
