Hello!
Sorry for any spelling and grammar mistake, I’m not a native english speaker.
As the title says I can not seem to get the most simple jme3 project to work as a browser applet. Just testing with the default example code when creating a new project I do as follows:
- I right-click the project, select properties, check “create applet”.
- I right-click the project, click on “Clean and build”. Output: “BUILD SUCCESSFUL”
- Navigate to project folder
- In dist/Applet i open run-applet.html i browser (tested with firefox, chrome, and safari)
I get an error and console shows as below:

I thought this was the right way do to it after reading here (se below),
https://wiki.jmonkeyengine.org/legacy/doku.php/sdk:application_deployment#browser_applet
but I must be missing something. Googeling for some hours has not gotten me anywhere, and official posts like this always is always a dead end since all links to any sort of browser applet instructions seems dead. Tested creating an applet with many different earlier working jme3 projects and tried running the applet on several computers but never succeeded. I have tried running other java browser applets and had no problem.
Can anybody please put me in the right direction? Or is the browser applet considered dead? Any thought or hint is very appreciated!
