Java stack - what are you guys doing?

Coming from the ABAP world, it would be really nice to know what people are doing out there on the Java stack.

I read recently that the Java stack doesn't provide access to the ABAP database (where all the business stuff is), and that this stuff needs to be accessed using RFC's and BAPIs.

This just picqued (sp?) my curiosity, what are you Java guys building out there? Web front ends? Stand alone apps? 'Business Strength' Hello World applications?

I'd love to see blogs on the types applications people are building on the Java stack.

Cheers,

Brad
