Don't see how that's any different than any other melee attack.
If you've got the PHB there, check the table of action types.
I'm not sure what it says in 3.5, but in 3.0, Grapple, Trip, and Disarm are Action Type: Varies, with a footnote mark indicating that they can be performed as part of a full attack action, or once on an attack or charge action, or even on an AoO.
Strike a Weapon is Action Type: Standard, and lacks the footnote mark. Thus, you cannot strike a weapon in 3.0 as part of a charge, full attack (including Whirlwind Attack), or AoO, nor can you make use of the Spring Attack or Expertise feats while Striking a Weapon.
