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 "app.jar"
I get the following message:
no main manifest attribute, in "app.jar"
Normally, if I had created the program myself, I would have added a main class attribute to the manifest file. But in this case, since the file is from an application, i cannot do that. I also tried extracting the jar to see if I could find the main class, but there are to many classes and none of them has the word "main" in it's name. There must be a way to fix this because the program runs fine on other systems.
