Cannot find any way to embedd a Java JAR file or java game onto a website

Im looking to add a game i had created in java to a website. All 8 could find was a Java converter called java2html, but that gasn't been updated since 2008 and I dint hlknow how I would take my hierarchy and put it into a website. The only other way I could find were applets, but I was told those were deprecated. Does anyone have a way to do this, or is a lost cause and I should just rewrite it c++ or something.
