Question
I'm using the GWTUpload lib for uploading, which works nicely. On the server side I override the executeAction()
method of the UploadAction
class.
But now I would somehow like to send some more information to the server e.g. to map the uploaded stuff to some user.
I'm not using sessions to identify anybody. I would only want to pass a simple extra id from the client to the server while uploading.
Can I modifiy the request parameters on the client side?
Solution
There is a few options, everything is described on GWTUpload wiki:
http://code.google.com/p/gwtupload/wiki/Servlets
Check "Sending additional parameters to the servlet" section.
For example:
Client side
MultiUploader u = new MultiUploader();
u.setServletPath(u.getServletPath() + "?myinfo=whatever");
Server side
String myInfo = request.getParameter("myinfo");
