I am thinking about a charting app that will use jfreechart on the server side (I need PDFs and other server side output anyway) and GWT + Canvas on the client so that users can do fancy things like curve fit in the browser. That means that when the client asks the server to render a chart, the client needs to get back a png and also some data (like scaling info, etc). I can of course do 2 rounds trips but I am thinking of combining it into one rt.
The idea is that the server response is an image/png but also sets a nonpersistent cookie in the header that encodes the data I need. The gwt app disassembles the cookie value (perhaps it is even json). If the cookie would be too big (unlikely), the cookie value becomes a message to the client that it needs a dedicated rt. Does anyone see a problem with this? Any thoughts are appreciated. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.
