Problem with exe4j

Hi, I have a project to be handed in tomorrow and really need to create an .exe file to run my java program.
There are several classes that are called within the main program.
All the classes are located in the same folder.

I have been trying to use exe4j to create this but it cannot seem to locate the class which contains the main class, i have tried typing the pathname in but it still doesn't run.

Does anyone have any suggestions??
Thanks.

I'm not familiar with exe4j but I would guess it needs a manifest.mf file as part of your project to tell it where the main class is.
