Hi all,

 

I am using Jersey inside Tomcat 7 and configured the application with @ApplicationPath("/"). It was working without problems.

 

This week I added EclipseLink, and when I start Tomcat, it throws a NullPointerException (see below). When I change the configuration to @ApplicationPath("/rest") or whatever, the NPE isn't thrown any more during Tomcat startup.

 

Since I want to run the application on ROOT path without any prefix, this isn't a solution.

 

Does anyone have an explaination or a solution? Thanks a lot in advance!

 

Regards

Duc
