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

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:
