how do I run java applets?












1















Is there a way to run a Java applet on Chrome or Firefox? I get the error message on the Java test page (https://www.java.com/en/download/installed.jsp) that Java won't run on Chrome or Firefox anymore because of the non-supported NPAPI - https://www.java.com/en/download/faq/firefox_java.xml).



I have an old set of *.class files with a .html to run it, and I just want to be able to run this applet somehow. But how?

          Is there a way to run a Java applet on Chrome or Firefox?



          No. Applets are no longer supported in Firefox or Chrome.




          Firefox no longer provides NPAPI support (technology required for Java applets)



          As of September, 2018, Firefox no longer offers a version which
          supports NPAPI, the technology required to run Java applets. The Java
          Plugin for web browsers relies on the cross-platform plugin
          architecture NPAPI, which had been supported by all major web browsers
          for over a decade. The 64 bit version of Firefox has never supported
          NPAPI, and Firefox version 52ESR is the last release to support the
          technology. It is below the security baseline, and no longer
          supported.

          Chrome no longer supports NPAPI (technology required for Java applets)



          The Java Plugin for web browsers relies on the cross-platform plugin architecture NPAPI, which had been supported by all major web browsers for over a decade. Google's Chrome version 45 and above have dropped support for NPAPI, and therefore Java Plugin do not work on these browsers anymore.

          If you already have the files on your machine, you can try the appletviewer that (used to? still does?) ships with the JDK (Java Development Kit).
