GWT - Get dom element's value from another page

Suppose I have two pages A.jsp and B.jsp. I have few elements on both the pages which has been generated through GWT code. Now I want to get the value of a element which is there on A.jsp while I'm sending a request through B.jsp and I want to pass that value into the request header. I'm generating a request with:

RequestBuilder rb = new RequestBuilder(RequestBuilder.GET, queryUrl);

I have tried using getElement() getElement however it is giving the elements which are there on that.

I want to access elements from other pages. Is it possible?

If this was possible, than theoretically any website would be able to get any data from any other page open in a browser, including credit card numbers, passwords, etc. Fortunately, it's not possible.

If you need to share data between different apps/pages that you control, you need to use a browser cookie, a server session, or a database/datastore to store this data. In other words, when something happens on page B, store this data somewhere where an app running in page A can access it.
