Sending image data over RPC... how do you plan to use this binary data
on the client side?
It's not possible... JavaScript does not have any image-processing
API.
You can do something like this:
- Create the image binary data on the server, and label it with some
unique ID (store in memory, filesystem, db wherever).
- Create a servlet, say ServeImageServlet that will do something like
this
doGet(...) {
String id = request.getParameter("imageID");
InputStream input = huntForImageUsingID(id);
response.setContentType("image/png"); // or jpg, gif...
OutputStream output = response.getOutputStream();
//copy all data from input to output
}
- In your RPC response, just send the URL.
Assuming that the servlet is mapped to /img, the URL can be
something like /img?imageID=abcd
- In the GWT app, use this URL to create a new Image(url)
