Oracle must be well pleased to pick up Dave Chappell, formerly a VP and chief evangelist at Progress Software's Sonic division (he's still on the management team there, according to this link). When that gets taken down, you can find his O'Reilly author profile here.
Dave will be development VP for SOA/ESB. I wonder which products that includes - Oracle Data Integrator perhaps? Good luck Dave, enjoy the ride at Oracle - I hope we meet again at another JavaOne some day.
PS, don't confuse him with any other Dave Chappell (like this one who runs an eponymous IT consultancy and speaks (for example) on BPEL, or this one who (I think it's safe to say) has no IT connection at all.
