Google App Engine 503 Error - Service Unavailable

Question

Over the past few days, every time I try to start my web application, an error appears - 503. This happens even when I try to go to the admin page. Is this a problem with Google?

Answer 1

When creating a GAE project, it is important that any class that extends HttpServlet and is used as an entry point to your Google application is displayed in web.xml found in war / WEB-INF, as shown in the figure below.

Created Java servlets that extend the HttpServlet should be displayed in the web.xml file as follows: -

GAE ecipse , Java-, TestServlet.class, HttpServlet .

URL-, TestServlet.class, web.xml( /test ) index.html. ( , eclipse, ).

Java- web.xml index.html, URL- URL- .

503 .
