For which database applications is Java particularly well-suited? JE is particularly well-suited for use in embedded environments where you need to store data and look it up fast without a heavyweight SQL database engine to consume resources you dont have. Namely, this is great for handheld devices, PDAs and other gizmos. With the craze of having JVMs [Java virtual machines] on most of these devises, JE solves a serious need.

What makes you convinced that Berkeley DB Java Edition will become the de facto standard Java API? A B-tree is a complex data structure to implement, but the exposed API is small and simple for such a complex data structure to implement. When the API and implementation are done right, with a good balance between design and speed, then there is very little incentive to rewrite this piece of general-purpose software. People will opt to use rather than rewrite, since the difficulty in rewriting far outweighs any advances you could possibly make. Furthermore, when made open as in this case, there is even less incentive to reimplement the code. If changes can be made to the open code and patches submitted, programmers are satisfied and less likely to rewrite JE in its entirety when they can patch it. Sleepycat has covered these bases well.
