I packed a war with web content and a java fx 2 application. If a button is clicked, the java fx app shall be opened in a new window. Therefore I embedd an applet in the web site. This works with chrome and firefox. But with internet explorer I get an error "invalid argument dtjava.js code: 0 row :1 character: 16290. In opera there is no reaction of the browser to start the jnlp (mime type for jnlp is specified in opera settings). Any idea?
