NetBeans Generated REST Service works for XML requests, but not JSON - rest

Question

I am using NetBeans to help me build a REST web service. My steps taken have been the following:
New Project -> Web Application
New File -> Web Service -> RESTFul WebService from Database
Select the Datasource (which is a MySQL DB)
Everything generates, right click on project -> Test RESTFul
WebServices
When I want to test GET(application/XML), I can get a result returned fine, I can also get an XML response from a Jersey Client I made after the fact. But when I test the JSON functions, I always seem to get errors:
exception
javax.servlet.ServletException: org.glassfish.jersey.server.ContainerException: java.lang.NoClassDefFoundError: Could not initialize class org.eclipse.persistence.jaxb.BeanValidationHelper
root cause
org.glassfish.jersey.server.ContainerException:
java.lang.NoClassDefFoundError: Could not initialize class
org.eclipse.persistence.jaxb.BeanValidationHelper
root cause
java.lang.NoClassDefFoundError: Could not initialize class org.eclipse.persistence.jaxb.BeanValidationHelper
My Database schema, which would really be the only thing I've written myself, is the following:
