Re: NullPointerException at startup

Hi Kevin,

The error you are getting seems to come from the ROOT application, a couple
of questions:

- how did you deploy your application?
- Is you application an a ear, jar or war file?
- You can attach the rest of the Catalina log to enable further
troubleshooting on the deployment issue you are having.

As a reference, the TomEE examples can serve as a good starting point to
know how to package and build your application(s):
You can download individual example code from here:
https://github.com/apache/tomee/tree/a5bd7f916eff5f6b942dc8bbf7fdcab194055949/examples
