How to use Java applet in Linux

Được đăng

Hi all, am using Debian linux with Firefox 60.8.0esr (64-bit). I know the whole spiel about Firefox not supporting java applets any longer, but I have some old IoT devices that i need to get configured and they use a java applet for some portions of the configuration. I understand Firefox ESR 52 still supports java applets, and i've downloaded version 52.9.0esr and extracted it to its own location. Now i can start it without interferin with my v60 profile by running it like: "./firefox --no-remote --profile ." I had to go into options and turn off the automatic update because otherwise it updates it to v60. Then I downloaded jre-8u221-linux-x64.tar.gz and extracted that. Now the question is how do i get the plugin installed into the Firefox v52? thanks

I wasn't able to make Firefox recognize the Java plugin via a symlink in "~/.mozilla/plugins" to the jre-8u221 and the jre-8u191, jre-8u144 works. I don't know why more recent Java plugin versions aren't detected.

In current Firefox releases you need a JNLP (Java Web Start) file to launch a java application.

Thanks! The 221 version worked OK for me for some reason. I put a link to jre1.8.0_221/lib/amd64/libnpjp2.so in ~/.mozilla/plugins and it showed right up in about:plugins Also had to run the jre1.8.0_221/bin/ControlPanel from the command line so I could add a security exception for the site, but after that the applet loaded right up and I was able to complete the device's configuration.
