JAXBException: "package" doesnt contain ObjectFactory.class or jaxb.index

I have been playing with JAXB / MOXy a lot lately, and it works great on all my tests and example codes. I exclusively using binding files, that's why I'm using MOXy.

Please note that in all my examples, I'm NEVER using an ObjectFactory nor a jaxb.index, and it works GREAT.

When I get back to my business, I get a nasty JAXB Exception saying that my package does not contain an ObjectFactory or jaxb.index.

My project also invovles Spring and Hibernate, JUnit and DBUnit.

Here is some sample code: I have an abstract class called AContributionPhysicalSupport.

package org.pea.openVillages.pojo.contribution.implementation;

Here is my binding file (there are other classes inheriting from AContributionPhysicalSupport....)

<?xml version="1.0" encoding="UTF-8"?>

And now my test :

@Test
public void testYATMarshal() throws Exception
{
    Video toto = new Video();
    toto.setPhysicalSupportId(new Long(1));
    toto.setSupportType("VIDEO");
    toto.setVideoLength(new Long(358));
    toto.setVideoSize(new Long(5775));
    toto.setVideoType("avi");

    FileReader videoBindFile = new FileReader(
            "src/main/resources/xml-mapping/ContributionImpl-binding.xml");
    List<Object> videoBindList = new ArrayList<Object>();
    videoBindList.add(videoBindFile);

    Map<String, List<Object>> videoMetaMap = new HashMap<String, List<Object>>();
    videoMetaMap.put("org.pea.openVillages.pojo.contribution.implementation", videoBindList);
    Map<String, Object> videoProperties = new HashMap<String, Object>();
    videoProperties.put(JAXBContextProperties.OXM_METADATA_SOURCE, videoMetaMap);

    JAXBContext context = JAXBContext.newInstance("org.pea.openVillages.pojo.contribution.implementation",
            Video.class.getClassLoader(), videoProperties);
    Marshaller marshaller = context.createMarshaller();
    marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true);

    marshaller.marshal(toto, System.out);
}

and last but not least the Exception :

... 33 more

More info :

  • My test package (where I have my JUnit test class) contains a jaxb.properties file
  • My JUnit test class is really a DBUnit / SpringJUnit class, since I want to marshal objects from a DB
  • Marshalling from DB or marshalling a simple object (like shown in my example) generate the same Exception
  • And, of course, adding a jaxb.index in the package doesn't change anything

Four eyes are better than two. I'm not getting what I'm doing wrong. If somebody sees it, please let me know.

Cheers

Provider com.sun.xml.internal.bind.v2.ContextFactory could not be instantiated - seems like you're not using MOXy but the built-in JAXB RI.

Please check the following post by Blaise:

Specifying EclipseLink MOXy as Your JAXB Provider

See also the following question:

Does MOXy need anything special when using with schema-derived classes?

lexicore

The answer provided by Lexicore in his comment did it for me!

I have setted the two packages as shown in Blaise's answer:

JAXBContext jc = JAXBContext.newInstance("com.example.pkg1:org.example.pkg2");

And that did it!

Thx man
