How do I run .jar files in Haiku?

I have the latest JRE package installed, but I don’t know how to run the .jar files. Any steps on this?

try
from terminal … java -jar filename.jar

I didn’t use the proper java package - after installing openjdk14 and using the step you listed they are working fine now… Thanks!

If you can run Java, means you can install the generic Opera Mini for feature phones and use it for web browsing?

Feature phones use J2ME. You might want to check out freej2me for that.

There was one script file to automatically open Opera Mini in Microemulator.jar on OS X. Since it’s a script file, it works on Linux also.
