Cannot create a proper working JAR file

Question

Hie,
Im facing a problem here to compile the JAR files. I went through the JAR tutorials at the java site but i cant still figure it out. MY problem is actually i need to create a JAR file that consist 3 folders and subfolders.
The main folder is --> classes
sub main1--> emmeeting
submain2-->image
submain3-->jwc
But, in this jwc it contains another two folders and there is another 3 folders inside those subfolders.
jwc ---> contains jwc 1 and jwc 2 as subfolder
jwc1 contains jjwc1. jjwc2 and jjwc 3
those filenames are examples only.
i used the command jar cvf classes.jar classes * class
and
even jar cf classes.jar -C emeeting. -C images . -C jcw
as these command will invoke every file inside it and create a jar but i still fail
When i click the jar that is created it says this error "Fail to load Main-Class Manifest attribute"...i went through the manifest and they say have to set up the main-class : classname .....so, which classname shud i use and plz tell me the best way to solve this .thanks

Answer 1

The main classname should be the path of the class which contains your static "main" method.
/mypackage/MyClassWithMainInIt
