JavaFX App Runtime Error on webpage but not on IDE

Basically my javafx application works fine on the IDE and on locally executed jar file but on the automatically generated .html page from netbeans it doesn't. I also get absolutely no indication as to what is wrong. This is the only message that I get when I click on "Click for details."

    Java Plug-in 11.101.2.13
Using JRE version 1.8.0_101-b13 Java HotSpot(TM) 64-Bit Server VM
