Re: call a java class from GWT

While written in both Java on the server and client side, GWT is javascript, once deployed, on the client side.  So the answer to your question is the same for any project written for Javascript. 

Based on your description of "Pinpad device", I'm guessing that your target user has this pinpad device installed on their machine and you want to communicate it.  We have a similar issue with a hardware sensor.  Our solution, on desktop, was to write a system tray application for each OS.  On mobile we wrap the web application in a UIWebView.  On all platforms we communicate with the web application and sensor helper via a websocket.  This is the only solution that we saw that limited the platform support requirements the most.

Hello, I have a java class that calls a dll from a Pinpad device and what I want to do is to run my java class from my GWT application. So how can I do that?.

I'll look forward your prompt reply.
