well, from looking at the code, it's either a null Struts ModuleConfig
or a null ServletContext. i'm guessing it is unlikely that your
ServletContext is null at that point :), so it would appear to be some
problem with your struts configuration that VelocityStruts isn't
handling all that well.
what version of struts are you using? can you share any of your
struts config? i'm not really a struts expert, but i could take a
look.
you could also try asking on the user@struts.apache.org list. someone
there might spot the problem quicker than me.

Thank you for your reply. The problem was that I was missing the 'load-on-startup' parameter for both Struts and Velocity in my web.xml file.
