问题 I am converting a JSP/Servlet dynamic web project to Struts 2 and the custom error pages (that previously worked with the JSP/Servlet version) have stopped working. When I induce a 404 error by accessing a non-existent page like abc.jsp , it throws below exception: SEVERE: Servlet.service() for servlet jsp threw exception The Struts dispatcher cannot be found. This is usually caused by using Struts tags without the associated filter. Struts tags are only usable when the request has passed

问题 To reproduce the error, simply upload a file(s) to any POST routes in Laravel that exceeds the post_max_size in your php.ini configuration. My goal is to simply catch the error so I can inform the user that the file(s) he uploaded is too large. Say: public function postUploadAvatar(Request $request) try { // Do something with $request->get('avatar') // Maybe validate file, store, whatever. } catch (PostTooLargeException $e) { return 'File too large!'; } } The above code is in standard Laravel

问题 I have a problem with a program I have done with Embarcadero C++ Builder. Part one: I want to make stand-alone .exe file, and according to that i have disabled "link with dynamic RTL" and disabled "link with runtime packages". But, every time i end my program, I get an error "Abnormal program termination". I've invstigated that and found a partial solution. When I enable link with runtime packages, that error does not appear, but .exe file won't run on PC which don't have C++ builder
