I updated my mac mini with latest OS X updates and the Java for OS X 2012-004 got installed .
now i am not able to run any applets in my application .
I have enabled the applet plugin and all settings looks fine .
I found out that the applet code needs to be fixed to work with the new update released by apple.
Can any one help me with what needs to be fixed in the applet code ?
We had a similar issue, and ended up changing the embed code by removing the "java_" prefix from the code and archive attributes. After making the change the applet would load in Firefox, Chrome and Safari on OS X.
