Can not run Java Applets in Internet Explorer 11 using JRE 7u51

Question

Today I updated my Java version to 7u51. After the installation, I cleared Java Cache, browser\'s Cache, and logged into a secure website that uses an Applet to provide cert

Answer 1

For Windows 8.1 Users.... there is a little note on the java download site which says:

"Downloading and installing Java will only work in Desktop mode on Windows 8 and Windows 8.1. See the Java on Windows 8 FAQ for more detailed information."

Unfortunately, "Desktop mode" is not the default mode in Windows 8.1. After installing java and wasting 2hours trying to get java working with IE11, I went back to oracles site...paid a bit more attention to that warning!! switched to Desktop mode, and reinstalled java... hey presto it worked.

Furious, that java download does not work with the default config of Windows 8.1, don't know who to be more angry with? Oracle or Microsoft? ( or me for skimming over the warning..)

Answer 2

The behavior of applets changes significantly with update 51. It's going to be a confusing couple of weeks for RIA developers. Recommended reading: https://blogs.oracle.com/java-platform-group/entry/new_security_requirements_for_rias

Answer 3

Its not about security settings .. its the UserAgent in IE11 ( in IE11 its Trident while all previous versions of MS IE were MSIE ) so I suppose that Java deployment tool cannot recognize new baby of MS .. and send you back to install Java ..

I already ask if there is any temporarily solution till Oracle guys make new release

JavaFx web not working with Internet Explorer 11 with JRE7

update:

btw applet is working at least on the oracle test java page : http://www.java.com/en/download/installed.jsp I just uninstall all JAVA from PC then reinstall latest version and disable then enable "Java(tm) Plug-In 2 SSV Helper and Java(tm) Plug-In SSV Helper " @ manage add-ons. before testing java on web. and it works ..

so I think its JavaFX not applet .. since JavafX is using dtjava.js while webstart(applet) using deployJava.js.

I ran into a similar issue that impacted all my browsers. After completely uninstalling all my JREs and JDKs then startig from scratch, I ran into the same issue. I'm running Win 7 pro 64 bit.

I detailed out the solution here (Why does Java 7 fail to Verify after successful JRE installation - Java 7 not running my any browser)

but basically I added this "-Djava.net.preferIPv4Stack=true" to my vm args (set in the Java Control Panel, under Java tab / View) and that solved the issues I was facing... seems like a hack but I guess the latest JRE does not handle IPv6 type requests properly

Answer 5

I had this problem on a client's pc in IE 11 with Java installed. It worked fine in Chrome, but wouldn't work in IE. After several days of TS, I just tried unchecking ActiveX Filtering in settings->safety. Now Java works fine.

Answer 6

We had the same problems with IE11 and new Java. Try to add your site to compatibility view. You can find here how to do it.

How to enable compatibility view in Internet Explorer 11

You can try now if it works or not. After that you can remove site from compatibility view and it should also run.
