Price of J2EE

I would like to package the EJB Open Source Server JBoss into my software but this needs J2EE software such as JAVAX.ejb.SessionBean, etc.

I can download J2EE FREE for evaluation purposes.

When I release it as part of my software (i.e. no longer just evaluating) what price is charged for it and how do I go about purchasing it?

If the price is too high I will have to review my strategy as the software I am developing is intended to sell for a low price.
