XUL and Java Server Faces
- Light deployment Mozilla and Firefox have an integrated XUL engine, you can use your favorite web browser to run XUL application.
- Keep business layer on the server side XUL is fine for UI but if you want to access your business logic on the server side it turns to nightmare. JSF and AJAX pattern are used to build a bridge between the client and the server.
- Efficient but with rich UI features XUL offers a rich UI for business applications. XUL is simple XML language. There are trees, tabbed panes, list boxes, wizards,layout and so on.
You have the ability to refresh the entire screen or a part of it. Look at Thunderbird : it's a XUL application.
