Java Applets在不同的IE 8+版本上坏了，但是前一段时间可以工作吗？

Question

We have a signed applet that was working for a long period of time, but last week some of our clients using IE 8 + 9 started to complain that the functions exposed by our applet aren't working anymore which we verified on-spot and on our testing machines. We are a bit confused as each time we come up with a possible root-cause, we go and test it on the client machine and it it turns to be not the one.

Has anyone observed that Applets stopped to work lately on IE8+ in the last couple of weeks due to one of the following reasons:

1. A Microsoft update.

2. A Java update. (The current one we are using is Java8u45)

   Many thanks in advance :)

   *** Update: Some users reported the issue on Chrome now too and there are no signs that the page is loading the applet at all.

Answer 1

Its Mainly the security issue by Java 8, Which is not allowing now to display or load the self signed Applets on browser. Please open configure java in settings and in security TAB put the URL of the html page which is using applet in Exception Site List

This should work for for. :)

Answer 2

We ended-up creating a stand-alone Java application that the browser talks to using XHR calls with CORS enabled. This way we came to a state where the printing logic is always loaded and ready to respond to requests coming from pages. Also, bringing out the applet from running as a browser extension/plugin to a stand-alone application means there no need to initialise the applet on each reload which yields better performance and user experience.

Thanks everyone for your replies.
