When an exception occurs, either a http 404 not found response is sent (when the action isn't found), or a http 500 internal server error response is sent (both using http headers). For 500 errors, the exception is also stored in the the request scope, according to the servlet and jsp specs, to allow :
A) either a JSP error page (with the error page directive) to be created to access the page scoped variable "exception", or B) a custom view page that has access to the request.getAttribute(name) to get the exception itself, using the key javax.servlet.error.exception.. i.e. request.getAttribute("javax.servlet.error.exception")

You could just set up a error page in your web.xml... Then you get your pretty error page for all errors, not just errors inside Actions...

what do you guys think about returning a result like
invalid.action.result or something along those lines when
the action
executed throws NPE? this way I can just map an global-result to show a pretty screen to the users
currently if an action throws NPE i get 500 Internal Server Error
