Apologies if this is the wrong place for this but here goes We are considering using JavaFX inside the Portal but I've run into a problem in proof of concept when I embedded a working applet using javafx format in a portlet (it works as a standalone web page) The error is the invalid magic value, which I understand is a way of saying that the java vm doesn't understand the format. Has anybody any ideas what could be causing this? Thanks Mike View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4135188#...
