How to mimic a subfile with java?

I am attempting to write a java application that would display a customer
list loaded from a db2 file.  When the uses selects a customer it will then
bring them to a customer detail screen.

My question is, what is the best way to load this list.  The method I used
was just a dow not eof loop that appended items to a JList.  This worked
fine for my testing, with minimum records, but when you start to get into
thousands and even hundreds of thousands of records it takes quite a long
time to load.

I don't expect to be able to get subfile load speeds(can I?) but there must
be methods to allow the speeding up of this process.  Has anybody ever done
anything like this?

Any help would be greatly appreciated
