Hi guys!
Need a quick feasibility look at my stack, cos we're growing our ops.

Struts + Spring
------
EJB 2.0
------
single instance BES on multi-partition

Is this ok? our main concern is the part on load balancing -- will Spring require any modifications/awareness; or is it EJB's problem; or not a problem at all?
Please advise or tell me it's a dummy qn thanks!
