Java to javascript communication (LiveConnect) broken recently?

Question

Look at this link:

http://www.chemaxon.com/marvin/examples/applets/sketch/chemicalterms2.html

This applet is trusted, signed etc. but I can't find configuration (OS/browser/Java) where it works...

I have:

• Ubuntu 12.04 / FF 25 / Java 1.7.0_45-b18
• Ubuntu 12.04 / Chromoum 30.0.1599.114 / Java 1.7.0_45-b18
• OSX 10.9 / FF 25 / 1.7.0_21-b12
• OSX 10.9 / Safari 7.0 (9537.71) / 1.7.0_21-b12

In all those environments I can see the same js error:

TypeError: document.MSketch.evaluateChemicalTerms is not a function

is LiveConnect broken? How can I fix it? Any help appreciated!

Answer 1

LiveConnect calls are not completely broken with latest jre release(7u45-b18) and allows with annoying security popup.

The JavaScript to Java (LiveConnect) security dialog prompt is shown once per Applet classLoader instance.

Eventually java guys may not support Live Connect call, so its good time to get rid of it.

Depending on your application logic you have to replace all your liveconnect calls with alternate logic.
