Simon-

something is happening to interfere with the successful completion of init() 
method of your Servlet
such as cannot find classes such as
'uk.co.weft.exceptionhandler.BugzillaExceptionHandler'
or one of the init-param in web.xml could be incorrectly spelled or not there
put in log.debug or System,out.println() statements every other statement in 
your init method so you can see each line being executed
in your init()
