The dictionary class is intended for this purpose, so you are doing the right thing.
If the parameter you need to pass is already available in the URL, then you can also read it directly from the url using the Window.Location class. For eg, if your jsp was invoked as /some.jsp?param1=value1¶m2=value2, then you can directly access param1 and param2 in your GWT code. But if you want to pass a totally different parameter, then the dictionary is the best solution. --Sri 2009/9/23 dann <[email protected]> > > Thanks for the reply.
