Hi, IMHO create two EJBs, one Stateless and one Stateful and create a normal Java class with the functionality you desire.
For the Stateful Session Bean place the Java class as a member variable of the EJB and deligate the required calls to it. For the Stateless Session Bean you can also put the Java class as a member variable of the EJB class but you have to be really carefull you do not store any state in the class as you will get very quickly into threading issues. If this state is an issue you will have to have the Java class as a method variable.
