I can think of a few ways to deal with it:
1) Disallow double-clicking on the client, ever. Add
ondblclick="javascript: return false;"
to the anchor tag(s). (The servlet engine never knows whether the user
single- or double-clicked. If you need that specific information, you
always need to deal with it on the client side.)
2) If you want to allow double-clicking to run the action twice, but you
don't want both clicks running at the same time, synchronize on a session
attribute.
3) If you want to disallow ever running the action twice in a row, set some
session attribute to remember the last action you ran, and reject any action
which matches the last action run.
