Changing Web applet

Hello,

I upgrade to Forms 12.2.1.3 recently, and i intend to change the current Java applet to other method more updated, beside this applet is compatible with IE only which is dead.

For example this is link shared with my clients :

http://servername.domain/forms/frmservlet?config=appname

or with Java Webstart :

http://servername.domain/forms/frmservlet?config=appname_jws

Here is an example how it looks with Java applet :

is there another way to display or run my application ?

Thank you
