How to use META-INF/MANIFEST.MF for the .jar ?

I already hava a .jar file done by someone earlier ?
This .jar have several main classes but I know the one I have to use .

Now I have to develop another .jar file (some classes) for which I need this .jar in the classpath ???

But for my .jar to work, I need to invoke the main class from the other .jar (Confusing :)

How can I utilize MANIFEST.MF ...

Let me knw..

entry in the calling jar

let say the name of the jar file that is developed by someone else is lib.jar,
your jar file name is abc.jar and you want to invoke the main class "a.b.Main"
that is there in lib.jar, You can do this as -

java -classpath lib.jar:abc.jar a.b.Main

theres a discussion of the process here thaty may help:

for example if the other required jar was a.jar and it was in the same directory as your application jar you would add the follwoing to your manifest:

Class-Path: a.jar

You cannot specify the absolute location of the jar, it needs to be the location relative to the application jar
