Runnable jar file generated by Eclipse wont execute?

Question

I generated a very simple runnable jar file using Eclipse\'s \"Export-->Java-->Runnable Jar File\" function. My HelloWorld class looks like this:

import ja         


        

Answer 1

Uninstalling all older java versions on my machine fixed the issue for me.

At my end I was able to run the .jar file with the command line, but not with the default double-click option. Afterwards the latter was working again
