I saw running jar from command line.

However my case is different. I put the jars needed for the main class under lib folder. So my jar is like this:

lib
META-INF
VideoFieldsResults.class

in the META-INF I have:

Manifest-Version: 1.0
Main-Class: VideoFieldResults

when I try to run:

java -jar VideoFormat.jar onBa32hgnBg,Lh-BKkLYYBU C:\VideoFormat2.csv

Where the last 2 are arguments I get:

Exception in thread "main" java.lang.NoClassDefFoundError: com/google/gdata/util
/ServiceException

Which does exists under one of the jars inside!

How can I run a command line specifying that all the jars under lib folder inside are required for the jar?
