Hi Joakim! I agree that more proper is just ContextHandler if I plan to serve just static files but how this could be invalid to use WebAppContext if WebAppContext is indirect child of ContextHandler?
You mention that this NPE is caused by not having set pathInfo correctly but it's absolutelly valid to have null pathInfo() [1]. Root context path (/) couldn't have pathInfo (/somePathInfo) by nature since otherwise it may collides with another servlet (with servlet deployed at somePathInfo context path to continue my example). [1] http://docs.oracle.com/javaee/6/api/javax/servlet/http/HttpServletRequest.html#getPathInfo() By the way I think that well-written app should never thrown NPE to the end-user (or end-developer). If code doesn't except null it should check for it before and throw high level exception explaining what's wrong. Do you think it will be helpful to file a enhancement bug for this (to produce more human error in this case)? -- Hezky den / Have a nice day Libor JELÍNEK VIRTAGE SOFTWARE // software - design - web Lucni 542 // 285 04 Uhlirske Janovice // Czech Republic support: +420 315 555 488 // cell: +420 777 205 142 email/jabber: [email protected] // web: www.virtage.com Visit our developer adventures at http://devblog.virtage.com!
