This used to work fine until a week or so ago, and I am not sure what has changed since then. I have just uninstalled what seems to be all the JVM stuff on my machine and reinstalled with the latest recommended Java version from java.com (1.6, update 23). The plugin works fine in IE and Firefox, but in Chrome it fails and the pages that try to use the plugin act as if Java is not installed. I have tried this in both Chrome 8 and Chrome 9 with the same result.

How can I diagnose and fix this?

What OS are you running? – Randolph West Jan 11 '11 at 22:07
Sorry, yes, it's Windows 7. – Chris Farmer Jan 12 '11 at 2:20
java.com/en/download/help/enable_browser.xml is what i read and it helped me figure out how to make java work on chrome. – chastity Dec 9 '11 at 14:39
@chastity: I have the same problem, and the Java plugin doesn't even appear in Chrome's list of plugins, so the java.com link above doesn't help. Looks like it's the 64-bit Java vs. 32-bit Chrome issue. – dandv Apr 2 at 3:10

If you are using 64-bit Windows, only IE supports 64-bit Java. Chrome and Firefox will only work if you install the 32-bit Java.

Thanks! I had discovered this combination worked a while back but never updated my question. – Chris Farmer May 20 '11 at 15:51
Had the same problem. Uninstalling 64-bit Java and installing the 32-bit version fixed it. – dandv Apr 3 at 20:30

I recommend removing Chrome completely, then reinstalling the Java, followed by Chrome. I presume you're using Windows.

The link doesn't tell anything that a superuser.com user wouldn't figure out... I have the same problem, and it looks like the cause is 32-bit Chrome vs. 64-bit Java. – dandv Apr 2 at 3:11
Thanks for the feedback, @dandv. While your tone is condescending, the information is useful. – Randolph West Apr 2 at 20:02
