December 2015 - As of September 2015 Chrome no longer supports Java Applets


This is from the Java website:

Java and Google Chrome Browser

Chrome no longer supports NPAPI (technology required for Java applets)

The Java plug-in for web browsers relies on the cross platform plugin architecture NPAPI, which has been supported by all major web browsers for over a decade. Google's Chrome version 45 (scheduled for release in September 2015) drops support for NPAPI, impacting plugins for Silverlight, Java, Facebook Video and other similar NPAPI based plugins.

Java applications are offered through web browsers as either a web start application (which do not interact with the browser once they are launched) or as a Java applet (which might interact with the browser). This change does not affect Web Start applications, it only impacts applets.

If you have problems accessing Java applications using Chrome, Oracle recommends using Internet Explorer (Windows) or Safari (Mac OS X) instead.

(Sue's webby person - I'm using 'Slimjet' ver which is based on Chrome and still allows java applets at the moment.)


December 2014 - Problems running Java Applets


The recent JAVA updates have brought in security changes that don't allow some java applet scripts to run, even with permission. This time they not only blocked the Fireworks applet but also the Slider applet we use for Christmas Day and New Year. There is a way to get the applets to run. This is from the Java website:

Starting with Java 7 Update 51, applets that do not conform with the latest security practices can still be authorized to run by including the sites that host them to the Exception Site List.

Starting with Java 8 Update 20, the Medium security level has been removed from the Java Control Panel. Only High and Very High levels are available.

The exception site list provides users with the option of allowing the same applets that would have been allowed by selecting the Medium option but on a site-by-site basis therefore minimizing the risk of using more permissive settings.

This worked for us using Windows 7, Java 8 update 25. Other operating systems and Java versions may be different.

You may have to restart your browser for the changes to take effect.
You may have to clear your cache.
You may still get a click-through warning about the applet.
For security reasons, you may want to remove the URL from the Exception List once it is no longer needed.
