Creating an executeble Jar file

Posted by Elly on February 06, 2002 at 12:58 PM

I created a manFile.txt file and put in it

>>Main-Class: com.cibc.rewardpts.RewardsMain

Then on the comand line I created my jar file this way

>>jar cmf manFile.txt jarFile.jar runClass\classes\com\cibc\rewardspts\RewardsMain.class

this creates a jar file with the heading manifest of


then I did this

>>jar uf jarFile.jar runClass\classes\com\cibc\rewardspts

to add the rest of my classes into the jar file.
By the way this is not the directory src, where I would have all my .java files but it is all my .class files, even my main RewardsMain, is a .class file!!!?

Then I try to run it like this

>>java -jar jarFile.jar

and this is the message I get?

Exception in thread "main" java.lang.NoClassDefFoundError: com.cibc.rewardpts.RewardsMain

Help ASAP please
