Thanks for this. I'll try that. I have produced WebViews before with no problems, although this is the first time that I've tried to do it facelessly. What I'd really like, of course, is a means of running JavaScript without a webview - i.e. provide a link to the JavaScript directly, without any of the html business.
In answer to your question though, this would be a client app. The server component, accessing the data, can be accessed through the javascript / webpage.
