Thread: I need to execute Applets in browser

Hello

First of all, since I am new here, I wish to greet everyone in the forum

I would really appreciate if you can help me with a problem. I am a teacher and I have a collection of physics applets that have been very useful to me for a long time. Since the last editions of Java it has been more and more difficult to use them, and now I can't at all. I tried some old browsers and Chrome extensions but it didn't work.
I need to know if there is a way to translate those web pages that contain applets into some other form that will allow me to run them, or if there is a third-party platform that supports it.
Thank you very much for your time.

I am trying with Appletviewer, however it finds errors in the code:java.lang.ClassFormatError: Name index 0 in LocalVariableTable has bad constant type in class file lithiccalendar
I guess it needs some reconversion

I have read the mentioned article, and I think it effectively identifies the problem. Unfortunately I don't have the sources, so I can't recompile.
Anyway thank you very much for your help.

I have decided to stop trying because my time for experimentation is short. In any case, thank you very much for your attention. My best regards.!
