Oracle Forms - How to open a URL in Chrome
Solution 1:
We've been running Forms in MS Internet Explorer ver. 8; an ancient one, yes - but - it supported Forms.
As of Chrome, you might be out of luck because Chrome won't support Java applets. It has to do something with support of NPAPI plug-ins which were first disabled and now not even supported. Java applet (Forms, right?) is such a plug-in.
What you might try to do is to enable NPAPI support in Chrome, but only if you (and your users) have a really old Chrome version lower than 45. Current version is 96, so we're talking about version that was out back in 2015 or 2016. Can you get such an old version? If so, you'd put chrome://flags/#enable-npapi
into the address bar, find & enable NPAPI, restart Chrome and - hopefully - make your Forms application work in Chrome.
Otherwise, I'm not sure you can make it work.
