Any java developers here?

[dern]

Has anyone done the sun java certification (js2e programmer and developer) recently? Can anyone recommend a book that I can use to study with?

I've got over 6 years of java experience but it's getting more and more common to do certification type tests at or before interviews if you don't have java certification already so I thought I'd bite the bullet and do mine.

Thanks for any pointers,

Mark
