I'd question why you'd jump into 257, as opposed to going with 255 first. With good knowledge of JSPs and
Servlets, plus a bit of knowledge of the tool, you'll find
test 255 isn't overly hard, although it is certainly a challenge.
I think having a development tool cert on your resume is impressive, especially if you want to get into the IBM world.
I like the UML cert, but I don't think it blows away interviewers. I'd rather have someone who knows how to code an use the tool properly, as opposed to someone who understands all the nuances of a sequence diagram.
SOA is hot. I looked at that cert, but haven't attempted it. I think SOA probably looks best on a resume right now, as every interviewer that doesn't know anything thinks that SOA is the greatest thing since sliced bread. Not to diminish SOA, but it does get incredibly overhyped.
Good luck, regardless of your decision.
