Hi,
I had a gwt + spring application and it run fine in my test
server. But when i deploy it to the production server, i'm facing a
problem to RPC call. Basically the function is just a button and it
will validate the kaptcha and send the input by GWT-RPC call and
email
to the admin.
Actually i'm not sure what's going on. Can any body give me a
hints ! thanks.
