Creates a new xlet. The xlet application programming model is very similar to the applet application programming model. Xlets are loaded into an xlet manager and controlled through a life cycle interface. This is similar to how an applet is loaded and run inside a browser. The main difference is that the xlet application programming model does not have implicit API requirements like java.applet which allows it to be used in a greater variety of product scenarios. Note: This template contains form code that allows you to design the xlet visually in the Form Editor.
