Accessing the Marvin Beans API?

I need some way to be able to access the API as described on this page. http://www.chemaxon.com/marvin/help/developer/beans/api/chemaxon/struc/PeriodicSystem.html

From the downloads page, I'm not sure which software to download so that I can access the API. Can someone help me out on this?

Dear Geoffrey!

   You can download any of our products to access this class. If you download Marvin suite, that you should import MarvinBeans.jar (or directly core.jar) to use that class. If you tell me exactly what you want to develop I can suggest what product can hold more valuable classes for you.
