- <Project>UserActivitySessionBean should better extend BaseDatabaseBean as no mail is being sent from this type of EJB
- added activity JMS queue
- implemented it in message-driven bean
- this whole thing may be shortened to only the EJB but then it is synchronous and people then will experience a slow down on heavy load
