Well actually if you have them in 2 places it can cause terminal errors, and at the very least will waste time and memory on startup. Common/lib is not an ideal solution, but you might want to try it at least to see if it works. In any case, if you install things like Slide (a Jakarta DMS/CMS webDAV-based framework), all the webDAV Servlets (and indeed everything else) goes in common/lib. Alternatively, have you try putting it inside the /lib directory of your webapp? It will then only be accessible to that webapp tho.
