Failed to load Main-Class manifest attribute from ...

Problem :

We come across this common exception when we are trying to execute a packaged jar file. Lets see how we can resolve this.

Exception I Encountered Was :

#########################################################################################
Failed to load Main-Class manifest attribute from /nfs/home/mrahamatullah/StaleContentProj.jar #########################################################################################

Solution :

This exception was caused when i compiled the jar file without the manifest file and was executing it.
The exact way to compile the jar file is to run :
From the jar files location > jar cvfm *.*
Where ManifestFile includes the classpath and main class definition.

Example :

jar cvfm StaleContentProj.jar manifest.txt *.*
