Hi! I'm trying to use AutoBean framework to transfer data from server
to GWT App. GWT-RPC is not good for me, because i need to cache
responces.
So I'm trying to use JsonpRequestBuilder to fetch data and AutoBean
framework for encoding/decoding.
The simple (and not working) aproach is like this:
---- servlet's doGet() method ---
String json = AutoBeanCodex.encode(data).getPayload();
String callback = request.getParameter("callback");
PrintWriter out = response.getWriter();
try {
out.write(callback);
out.write("(");
out.write(json);
out.write(");");
} finally {
out.close();
}
--- client ---
JsonpRequestBuilder jrb; // = ...
jrb.requestString(url, new AsyncCallback<String>(){
public void onSuccess(String result) {
AutoBean<DataType> bean = AutoBeanCodex.decode(factory,
DataType.class, result);
DataType data = bean.as();
//....
}
public void onFailure(Throwable caught) {
}
});
-----
Unfortunately, this does not work, because returned data is not
actualy a String, it's a JavaScript object.
I've tried to escape json on the server to make it String:
---
out.write(callback);
out.write("(\"");
out.write(escape(json));
out.write("\");");
---
This works, but in my case it increases responce size from 700kb to
3Mb which is really not good.
Any ideas what to with this?
