If you want to build anything with reliability, testable and amazing echo system j2ee is the way to go.

I was a skeptic myself always thinking it's too heavy and too large and too slow, but after fate handed me a codebase of j2ee platform and seeing how reliable and no effort is put into maintaining it rather just focus on the application logic.

I would always chose java for any software that's expected to last 10 years plus and should work reliably.
