#TIL : Runing old java applets on brower

Mostly morden browser has stop support Java plugins, so you can't run Java applet on browser.

Temporary way :

• run in IE or Safari
• run in an old Firefox (version 23)

And what if old java applet can't be runned on Java 8 because of weak signature algorithm. Try this

• Open java.security file :
  • In MacOS, located in /Library/Java/JavaVirtualMachines/jdk[jdk-version].jdk/Contents/Home/jre/lib/security
  • In Windows, located in C:\Program File x86\Java\jre\lib\security
• Comment this line, jdk.certpath.disabledAlgorithms=MD2, MD5, RSA keySize < 1024
• Rerun applet
