如何创建仅包含子文件夹内容的Java jar文件？

Question

Now I am in a temp folder in my dos console. there is a classes folder inside the temp folder. that classes folder contains all my classes started with com.companyName.app folder structure. I use "jar cf project.jar classes\\*" to create the jar file but it starts with classes folder. I don't want the classes folder. The top level folder I expected is the com. How can do it? or I have to cd to classes folder to do that? thanks,
