trying to run test java from cmd

I am trying to run my java program from command prompt. When I do the main method inside my class it works just fine whe I use the following command : path\out\production> java -cp .;"../../../lib/" Class Package.ClassName but when i try to run the class test with the same command but changing out to test like these: path\out\test> java -cp .;"../../../lib/" Class Package.Class Name it gives me an error . I don't really know what I am missing Thank you in advance
