I have built an application using Swing and exported it as runnable jar file and converted it to .exe file. Its working fine in some systems, but in other systems a popup error is shown up saying "The main startup class could not be found" and the application exits.

Has anyone faced this kind of problem?

Please check your generated Manifest file for classpath.

Check this link..."Could not find the main class" when double-clicking .jar file
