Issue with pop_os.jar loading or execution
Issue with pop_os.jar loading or execution
While attempting to launch a .jar file, it opens into the Archive Manager instead of the Java Runtime Environment. When using other applications, it disappears from view. I confirmed enabling "Allow executing file as program." Despite installing Java via both Terminal and Synaptic Package Manager, the problem persists. After the latest Java installation via Terminal, I read about potential configuration steps, though details remain unclear.
Launch terminal, move to the directory containing your JAR, then execute "java -jar [filename].jar". Some JARs aren't directly runable on the system and require this approach.
It functioned correctly, thanks for your assistance. The reason my member tag shows as empty is unclear.
a jar is not executable—it's merely an archive. When using Java, opening it via the standard dialog sends the filename directly to the binary, which doesn't function correctly because Java requires a class name with extra parameters. To fix this, set the -jar option properly: java -jar %1. If it's not configured right, you won't be able to run the jar by double-clicking. The simplest solution is to ask the developer for guidance on launching the distributed app. You can run it simply as "java -jar %1," or more complexly with additional parameters. Another option is requesting a proper start script instead of relying on user input. If the project lacks one, it might just be provided out of curiosity—what you try to do anyway?
