Although you could certainly return the bytes of an image via RPC, once you have them on the client side, there is no way to actually turn those bytes into an image (or even save those bytes to the file system). That is a limitation of the XMLHTTP request and javascript, not a limitation made by GWT.
You could either return a URL from your RPC and then create an imageWidget using that URL, or you could simply skip the RPC altogether and create a GET request URL that presumably ends at a servlet capable of returning your image. And use that directly in the ImageWidget, something like new Image(GWT.getModuleBaseURL()+"images/ ImageServlet?param=foo"); -jason On Oct 21, 2008, at 1:31 PM, Alley wrote: > > Hi, I need to create an rpc to return an image. > > Thanks, > Alley > > --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.
