Subject: Please cherry-pick: (be careful with project-specific names!)
X-Git-Url: https://git.mxchange.org/?a=commitdiff_plain;h=73025a275b535b47e09dc8ddf2387fdb5dec3793;p=jjobs-ejb.git

Please cherry-pick: (be careful with project-specific names!)
- <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
