Hi Brian, First you should ask on the freebsd java mailing list, not here. Second, 200MB of ram isn't that big anymore these days for a server, you might consider your system needs more? Java isn't know for small programs. Java's strength is it's write-once, run-anywhere feature, and as a result it's going to be much more resource consumptive than a compiled C program. Last, most of this will probably be swapped out, so what you want to pay attention to in top is the Swap: line. When your app starts, you should see swap loaded up - what you should be concerned with is if you see a lot of in-and-out on the ram allocated, also you might try running systat -vmstat you will get a better idea of what your system is doing that way rather than just looking at top's output.
