I downloaded a jar file and it was automatically saved to my downloads folder (I am using mac osx mountain lion). When I click on it, it automatically starts and everything is fine.
However, when i move the folder that contains the jar file and some other files to another directory (yep, I want to clean up my downloads folder) i am unable to start the jar file. I always get the error:
The Java JAR file "example.jar" could not be launched.
Check the Console for possible error messages.
What can i do to solve this problem?
EDIT: When I try to launch the jar file via the console i get this error:
Unable to access jarfile ./example.jar

To open a jar file in Windows, you must have the Java Runtime Environment installed. Alternatively, you can use decompression software, such as an unzip utility, to view the files in the jar archive.
On Windows 10 and Windows 11, JAR files don't open by default as there are no built-in apps to handle this file format. But, you can install the free Java utility and access this file format on your PC.
It's probably the case that the JAR was downloaded along with other directory/files. So it's possible that some files are missing when you try to run the application.
Try opening a terminal and run:
$ java -jar name.jar
Where name.jar is your JAR file.
