How To Includes a Simple Jar File?

Hello, I hope this is an easy question.

I have an EJB that is part of an SA.  It uses a simple Java class that I need to have in a separate project.  I made a Java project, with this class and a jar target.  Everything builds fine.

But how can I include the simple jar in something deployable?  I can't include it in an EJB module, because it is not an EJB.  There does not appear to be a way to add a simple jar project to an SA either.

This all works if I place the simple class in the EJB project, and so it ends up in the SA, but I need it to be separate.

Am I missing something?

Thanks
