J2EE specs says librairies of a webapp must be in /WEB-INF/lib (that's
for the part about subjet line where you use /lib)
Now, for you mail content you seem to be indeed using WEB-INF/lib, and
it seems to be the 3 libs required by wicket example. I suggest you
investigate the possibility of having downloaded a broken jar. Maybe,
try switching away from a beta version....
