How to Identify JAXB Implementation Classes?

A

You can use the following simple Java program, JaxbClassInfo.java, to Identify JAXB Implementation Classes:

// Copyright (c) FYIcenter.com
import javax.xml.bind.JAXBContext;
import javax.xml.bind.Marshaller;

public class JaxbClassInfo {
   public static void main(String[] args) throws Exception {
      JAXBContext c = JAXBContext.newInstance("com.fyicenter.demo");	  
      Marshaller m = c.createMarshaller();
	  System.out.println("JAXB Implementation Classes:");
	  System.out.println("   JAXBContext: "+c.getClass());
	  System.out.println("   Marshaller: "+m.getClass());
    }
}

Compile and run JaxbClassInfo.java as shown below in the .\src\ folder, where the data type classes were generated by XJC:

\fyicenter>cd src

\fyicenter\src>\local\jdk-1.8.0\bin\javac JaxbClassInfo.java

\fyicenter\src>\local\jdk-1.8.0\bin\java JaxbClassInfo
JAXB Implementation Classes:
   JAXBContext: class com.sun.xml.internal.bind.v2.runtime.JAXBContextImpl
   Marshaller: class com.sun.xml.internal.bind.v2.runtime.MarshallerImpl

As you can see, the Java SE implementation of JAXB API has the "com.sun.xml.internal.bind" package name.
