Thanks Jakub.

The NetBeans project seems to be using Jersey directory structure for
resolving libraries and that gives the error attached in the image. I
resolved the references but building the project gives the following error:

C:\workarea\samples\JsonFromJaxb\JsonFromJaxb\build.xml:22: taskdef
class com.sun.ws.rest.tools.ant.WebResourcesProcessorTask cannot be found
