I have a Windows 7 host. The same program runs fine with gradlew bootRun
.
I am not using a web.xml. But my build.gradle is along the lines of https://cloud.google.com/appengine/docs/standard/java/tools/gradle.
I am not running through eclipse (similar problem is reported here: mvn appengine:run - error 403 (spring boot web with jsp)).
