SCJP and Reading

Just passed my SCJP exam a few days back. I was suppose to take it two years ago but I never got it going as I'm too lazy to read (SCJP Book by Sierra and Bates -- good and fun book). But now that I've passed it, I'm still in the mood for more reading. I'm kind of hoping it continues on as I'm really much more of a technical person than a people person (management and stuff).

I also have a voucher for the SCWCD exam on the way. But it should pretty much expire this same year (thanks HP). I haven't found a decent reading material for it yet though.

Currently reading Pro AJAX and Java Frameworks by N.Schutta and R.Asleson.
