title: How to resolve java.lang.NoClassDefFoundError: javax/xml/bind/JAXBException
body: <p>I have some code that uses JAXB API classes which have been provided as a part of the JDK in Java 6/7/8.  When I run the same code with Java 9, at runtime I get errors indicating that JAXB classes can not be found.</p>
  
  <p>The JAXB classes have been provided as a part of the JDK since Java 6, so why can Java 9 no longer find these classes?</p>
