Specifying the EclipseLink Runtime

In order to use EclipseLink Dynamic MOXy as your JAXB implementation, you must identify the EclipseLink DynamicJAXBContextFactory in your jaxb.properties file.

  1. Create a text file named jaxb.properties, specifying DynamicJAXBContextFactory as the factory used to build new JAXBContexts.
    javax.xml.bind.context.factory=org.eclipse.persistence.jaxb.dynamic.DynamicJAXBContextFactory
  2. Copy the file to your application package (or any of your packages on your classpath).
  3. Use the standard JAXBContext.newInstance(String contextPath) API to create a DynamicJAXBContext. When this method is called, MOXy attempts to locate a jaxb.properties file on the classpath in the package specified by contextPath, and use the specified factory.
    DynamicJAXBContext jaxbContext = (DynamicJAXBContext) JAXBContext.newInstance("mynamespace");

Because you do not need to change any application code, you can easily switch between different JAXB implementations.

The JAXBContextFactory can

  • Create a JAXBContext from an array of Classes and a Properties object
  • Create a JAXBContext from a context path and a ClassLoader
