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 jaxb.properties file to the context path used to create the JAXBContext.

  3. Use the standard JAXBContext.newInstance(String contextPath) API to create a DynamicJAXBContext.

    DynamicJAXBContext jaxbContext = (DynamicJAXBContext) JAXBContext.newInstance("org.example.mypackage");

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

Instantiating a DynamicJAXBContext

The following methods on JAXBContext can be used to create new instances of DynamicJAXBContexts:

public static JAXBContext newInstance(String contextPath) throws JAXBException
public static JAXBContext newInstance(String contextPath, ClassLoader classLoader) throws JAXBException
public static JAXBContext newInstance(String contextPath, ClassLoader classLoader, Map<String,?> properties) throws JAXBException
  • contextPath – Location of jaxb.properties file.

  • classLoader – The application's current class loader, which will be used to first lookup classes to see if they exist before new DynamicTypes are generated.

  • properties – A map of properties to use when creating a new DynamicJAXBContext. This map must contain one of the following two keys:

    • org.eclipse.persistence.jaxb.JAXBContextFactory.XML_SCHEMA_KEY, which can have several possible values:

      • One of the following, pointing to your XML Schema file:

        • java.io.InputStream

        • org.w3c.dom.Node

        • javax.xml.transform.Source

    • org.eclipse.persistence.jaxb.JAXBContextProperties.OXM_METADATA_SOURCE, which can have several possible values:

      • One of the following, pointing to your OXM file:

        • java.io.File

        • java.io.InputStream

        • java.io.Reader

        • java.net.URL

        • javax.xml.stream.XMLEventReader

        • javax.xml.stream.XMLStreamReader

        • javax.xml.transform.Source

        • org.w3c.dom.Node

        • org.xml.sax.InputSource


        NoteNote:

        If using one of these options, a package-name element must be defined in the xml-bindings element of your OXM file.


      • A List of objects from the set above.


        NoteNote:

        If using this option, a package-name element must be defined in the xml-bindings element of your OXM file.


      • A Map<String, Object>, where String is a package name, and Object is the pointer to the OXM file, from the set of possibilities above.
