Java HotSpot Virtual Machine

How do I set a larger stack size in the HotSpot client?
I've programmed a really simple recursive program, but it only gets through about 5500 recursions. I'm working on an algorithms project, so I need to be able to call a procedure recursively tens of thousands of times without the Stack overflowing. It looks like there's no easy way to increase the stack size, and only allowing 5500 basically empty recursions is really pathetic.

Any help very much appreciated.
