EXT: Re: Cannot display applet page with Amazon Corretto, IcedTea-Web on Windows

[Gorz, Damian (GE Renewable Energy)]

Sorry for the late response...

The applet web page worked for us using Oracle JRE and Firefox 52 ESR which was the last version to support plugins. We want to continue using FF52ESR for the applet page but transition to Amazon Corretto and possibly install something like IcedTea-Web to make it work.
How I came to conclusion ITW supports applets on windows? I went to page about ICW;
https://icedtea.classpath.org/wiki/IcedTea-Web
There first sentence says it contains a browser plugin for running applets and Java Web Start. Then I went to latest version 1.8 page;
https://mail.openjdk.java.net/pipermail/distro-pkg-dev/2019-March/041321.html
and saw windows MSI installer so thought ITW works on windows.

Thank you for your help.

And you never will. ITW's plugin was always NPAPI, which was never done in Explorer and so it is not in edge - they have theiurs activex. To support that, native plugin would be necessary to rewrite from scratch.
Another issue is, that npapi plugin was never ever build or release for windows.  So although it should be possible to build it, it is unlikely it will work good enough for production (== work at all?) In addition npapi si already deprecated or even disabled in 99% of browsers. So do nto waste your time (or anybody else) and move to 21st century. If you really need yours applets, move them to jnlp protocol (it supports applets). If your appelts requires javasctript and browser, you are doomed, and there is no place for you in future. Sorry (but it is unlikely,I had already seen hundred of appelts move to jnlp flawlessly)

Please, where have you come to conclusion ITW on win supports applets? I will need to fix that doc.
