Question

I would like to set up an AppEngine service locally. Everything compiles, but when i try to run the project, I get this error:

SEVERE: Received exception processing C:\Users\eazyigz\Google Drive\Books\Android eBooks\Apress Practical Android Projects\PracticalAndroidProjectsSourceCode\Projects\08_GameService\war\WEB-INF/appengine-web.xml
com.google.apphosting.utils.config.AppEngineConfigException: appengine-web.xml does not contain a element.
See http://code.google.com/appengine/docs/java/config/appconfig.html#Using_Concurrent_Requests for more information.
You probably want to enable concurrent requests.

When I do enable threadsafe, Eclipse shows this compilation error:

I simply don’t understand what is happening. Can somebody shed some light?

Thank you,

You should put <threadsafe> into appengine-web.xml file, not web.xml
