Best Compatability Method

Is there some way to best ensure compatability for an Applet deployed on the web? I am testing an Applet I made for research I am doing that collects data from the participants. However, the Applet won't load for some people. The most common issues are plug-ins are needed and the classes are not found (actually it is something like Unsupport class version for major major minor minor or something).

Any helpful hints?

I forgot to mention, if it matters, I use Eclipse 3.4.1 and Java 6.

Java 5 (and, to some degree, 1.4) are still pretty common in browsers. So if you want to reach a wide audience (thus avoiding the unsupported class version error), you should use Java 5 at the most, not Java 6. (And make sure that your compiler/IDE generates class files for Java 5.)
I agree. Here's the link:
