Servlet 500 Cannot Initialise
Hi, getting an error one mydeployed application that I'm a little stumped on. First of all something of relevence is that XDoclets aren't automatically generating much in the way of content in my web descriptors, so I have had to write them manually.
Error:

I'm still using the same names as the tutorial files, as I'm just changing the application and removing the tutorial slowly so I make sure I understand whats going on.
Thanks
