Cannot get EclipseLink MOXy to work

Question

I'm new to JAXB and I want to change the default namespace prefix using EclipseLink MOXy. My package-info.java has the following code lines:

@javax.xml.bind.annotation.XmlSchema (
namespace="http://namespace.mysite.com/",
xmlns = { 
    @javax.xml.bind.annotation.XmlNs(prefix="myns", 
               namespaceURI="http://namespace.mysite.com/")
},
elementFormDefault = javax.xml.bind.annotation.XmlNsForm.UNQUALIFIED
)
package com.core.mymodel;

And my jaxb.properties file has the following line:

javax.xml.bind.context.factory=org.eclipse.persistence.jaxb.JAXBContextFactory

I have added eclipselink.jar to the CLASSPATH, both package-info.java and jaxb.properties files are in the same package as my model classes, however, when I run the program I get the following error message:

javax.xml.bind.JAXBException: Provider org.eclipse.persistence.jaxb.JAXBContextFactory        not found
- with linked exception:
[java.lang.ClassNotFoundException: org.eclipse.persistence.jaxb.JAXBContextFactory]
at javax.xml.bind.ContextFinder.newInstance(Unknown Source)
at javax.xml.bind.ContextFinder.find(Unknown Source)
at javax.xml.bind.JAXBContext.newInstance(Unknown Source)
at javax.xml.bind.JAXBContext.newInstance(Unknown Source)
at javax.xml.bind.JAXBContext.newInstance(Unknown Source)

I have tried this with EclipseLink versions 2.3.0 and 2.0.2 and still got the same error message. Does anyone happen to know what could be the problem?

Many thanks in advance

What environment are you running your application in Java SE, application server, OSGi? — bdoughan
Are you creating the JAXBContext on an array of classes or a String context path? — bdoughan
I'm creating the JAXBContext on a String context path. Here is the code line: JAXBContext context = JAXBContext.newInstance("com.core.mymodel"); — Khutsi
Just for clarification, "com.core.mymodel" is the name of the package that contains the model classes and the jaxb.index file. — Khutsi

You appear to have your jaxb.properties file correct based on the exception message:

javax.xml.bind.JAXBException: Provider org.eclipse.persistence.jaxb.JAXBContextFactory        not found
- with linked exception:
[java.lang.ClassNotFoundException: org.eclipse.persistence.jaxb.JAXBContextFactory]
at javax.xml.bind.ContextFinder.newInstance(Unknown Source)
at javax.xml.bind.ContextFinder.find(Unknown Source)
at javax.xml.bind.JAXBContext.newInstance(Unknown Source)
at javax.xml.bind.JAXBContext.newInstance(Unknown Source)
at javax.xml.bind.JAXBContext.newInstance(Unknown Source)

To confirm that org.eclipse.persistence.jaxb.JAXBContextFactory is on your classpath can you try:

JAXBContext jc = JAXBContextFactory.createContext("com.core.mymodel", null);

To do a more basic confirmation can you run:

System.out.println(org.eclipse.persistence.Version.getVersion());
