double clicking jar files on the desktop

[schnook]

When I try to double click any jar file it always comes up with can not find main class. Is anyone else encountering this difficulty? I am using 10.1.3 It doesn't seem to matter how the jar files were built.
:cool:

When you compile your jar file, you have to include a main class manifest file when compiling. If you don't, you'll get that error.

The file should look something like this

Main-class: TestApp

Thats it. One line.

man jar for more info
