Can you post here the content of the manifest file.

You can find lots of information from the Suns' tutorial as well.

Here is the link.

Search the forum, you can find lots of such similar thread discuss here in our community.

i too have the similar issue like urs in the past...
please compile ur java files, create a *.jar file again.
The important thing is too add a "blank" line break at the end of the manifest file.

you could also refer from here : Lesson: Packaging Programs in JAR Files (The Java™ Tutorials > Deployment) <----- recommended xD
