WO license with X Server

Hi there

We have a couple of XServe boxes one with Panther server and the other 
with Tiger server. I understand that a deployment license for WO comes 
with Tiger server. I would like to try out building WO projects as 
servlets using WO5.3, but to do so I need to enter a deployment license 
key.

Is it possible to use the license that comes with Server in this way? If 
so, given that it seems that the printed materials that came with the box 
have disappeared into the company cellar apparently not to be seen again, 
is it possible to find the license key anywhere on the machine itself's 
filesystem?

Thanks very much for any thoughts
