Hello,
We are starting new project - the portal with a large number of users simultaneously logged in 17000.
Portal will be processed and presented mainly XML documents.
50% of the logic will be available on the outside through the ESB.
Target solution (portal) will be run on JBoss Application Platform.
Technology (portal):
1. Front Controller - Struts 2
2. Business logic:
a) EJB 3 (local SLSB) or Spring
b) Business Delegate Pattern (access ESB)
3) ORM JPA
Please help in the selection in item 2a on the above assumptions (EJB 3 or Spring).
I would also mention that the performance is crucial.
Thanks in advance
