Can't execute jar- file: “no main manifest attribute”

Question

I have installed an application, when I try to run it (it\'s an executable jar) nothing happens. When I run it from the commandline with:

java -jar \

Answer 1

You might not have created the jar file properly:

ex: missing option m in jar creation

The following works:

jar -cvfm MyJar.jar Manifest.txt *.class
