Hi, There is a bit change in approach. Somehow i am now able to connect to GWT from my external HTML/website. The way I have done is on click of a button in my html , I open a new window which loads the GWT Host HTML which in turns calls a JSNI method. The problem is now to pass some parameter from my website/HTML to GWT native method.
Please help me out to get some way. Thanking you for much needed help & co-operation.
