It's 2020, web clients aren't a thing anymore.
"Java applets were introduced in the first version of the Java language, which was released in 1995. Beginning in 2013, major web browsers began to phase out support for the underlying technology applets used to run, with applets becoming completely unable to be run by 2015–2017. Java applets were deprecated since Java 9 in 2017 and removed from Java SE 11 (18.9), released in September 2018."
