Re: Best Practice for JSON object recreation on client

I have tried something like: 

@JsType(namespace=GLOBAL)

public class Record {

String id;

String date;

String data;

public Record() {

}

}

As mentioned above, I created a JsInterop wrapper for the JSON class in javascript :

@JsType(isNative=true, namespace=GLOBAL)

public class JSON {

public native static String stringify(Object obj);

}

After calling : 

  Record record = new Record();

       record.id = "1";

       record.date = "20";

       record.data = "30";

GWT.log(JSON.stringify(record));

I got : 

{"id_1_g$":"1","date_1_g$":"20","data_1_g$":"30"}

I am not sure why does GWT adds _1_g$ to all properties. the solution is to annotate properties with @JsProperty(name="property name")

Hello everybody,

First of all a big THANKS to everyone involved in developing and supporting GWT.

please correct me wherever I am wrong:

In the past you used JsonUtils.safeEval() to create a JavaScriptObject from a JSON String. As i understand it, jsinterop annotations on classes not extending JavaScriptObject are now preferred over JavaScriptObjects.

What is the recommended, future-proof way of having a server-client common class (i.e. package "shared") that can be:

- created and accessed in a JVM servlet
- created and accessed from the client end
- serialized to JSON / deserialized from JSON to the specific class on the server (e.g. using GSON)
- serialized to JSON / deserialized from JSON to the specific class on the client

Background: Using WebSocket Servers to bidirectionally transfer JSONified objects. No GWT-RPC involved.
Trying to avoid duplicate environment specific classes, boilerplate code etc.

Thanks for every clue and please overlook me not having a native English interface. ;)



kind regards,
max
