    Question 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.

    Applets can often be rewritten to execute as a desktop app by wrapping the applet code in a class with a frame and providing the interface/methods that the applet uses and calling the applet's methods as needed.

    There is a program in the SDK that will execute applets: Appletviewer
    See if that does what you want

    I do not think there are any browsers that now support applets.
    If you don't understand my answer, don't ignore it, ask a question.

    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

    Do you get that error with more than one applet?
    What version of the JDK are you using?

    Do you have the source files for the applets? Can you compile them?

    Try posting the error message on Google. Here is one of the responses I get:

    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.

    Can you post one of the applets on a site where I could download it?

    What version of java do you have?

    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.!
