I am new to GWT and am trying to implement a file upload functionality. Found some implementation help over the internet and used that as reference. But have some questions related to that:
The actual upload or writing the contents of file on server(or disk) will be done by a servlet. Is it necessary that this servlet (say MyFileUploadServlet) extends HttpServlet? OR I can use RemoteServiceServlet or any other servlet or implement any other interface? If yes, which method do I need to implement/override? In my servlet, after everything is done, I need to return back the response back to the client. I think form.addSubmitCompleteHandler() can be used to achieve that. From servlet, I could return text/html (or String type object) and then use SubmitCompleteEvent.getResults() to get the result. Question is that can I use my custom object instead of String (lets say MyFileUploadResult), populate the results in it and then pass it back to client? or can I get back JSON object? Currently, after getting back the response and using SubmitCompleteEvent.getResults(), I am getting some HTML tags added to the actual response such as : pre> Image upload successfully /pre> . Is there a way to get rid of that? Thanks a lot in advance! Regards, Ashish -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.
