My interactive educational software has applets embedded in webpages. All was fine until I installed the latest Java7. Now all the applets are blocked, with some comment about my security settings being responsible for the blockage. I've tried everything I know to no avail. How do I get my applets back? What good alternative(s) do I have to the use of applets for interactivity? Thanks

To protect from scummy criminals, the security settings for running applets have been steadily increasing over a number of Java updates.
The main thing is to sign your applet jars using a proper certificate from a trusted authority. Depending on the user's java security settings (in the Java control panel) they may stil see warnings, but should be able to run signed applets.
