Simple JAXB client doesn't work in ServiceMix/Felix


Hi,



I sent this to ServiceMix mailing list, but thinking this may really be the underlying OSGi framework issue. So I'm also sending this to this mailing list hoping users in this group would be more OSGi focused.



I had a post for help on JAXB not working in ServiceMix earlier. But that configuration was quite complex. I now simplified it to a simple JAXB client bundle (no longer embedded/wrapped). It has a single class, Person, which is annotated with @XmlRootElement and a jaxb.index resource file that contains a single line of the class name "Person".  The JAXB client code simply calls JAXBContext.newInstance("package") to get the JAXB context in the constructor. A blueprint deployment descriptor simply defines the JAXB client as a bean. I deployed it into the ServiceMix and the bean creation causes the  "package doesnt contain ObjectFactory.class or jaxb.index" exception from the call to the JAXBContext.newInstance(). Here's the details about the code. Hope someone can spot what's missing:



The Person class:



package

mil.army.security.ts3.jaxb.personnel;


import

javax.xml.bind.annotation.XmlRootElement;


@XmlRootElement

public

class
Person {

    private int customerNumber
;

    ...



   // getters and setters

   ......

 }





The JAXB client code:



package mil.army.security.ts3.jaxb;



import java.io.ByteArrayInputStream;

import java.io.ByteArrayOutputStream;

import java.io.InputStream;

import javax.xml.bind.JAXBContext;

import javax.xml.bind.JAXBException;

import javax.xml.bind.Marshaller;

import javax.xml.bind.Unmarshaller;

import mil.army.security.ts3.jaxb.personnel.Person;



public class PersonTransformer {

    JAXBContext jaxbContext = null;

    Marshaller marshaller = null;

    Unmarshaller unmarshaller = null;

    public PersonTransformer() {

        try {

            jaxbContext = JAXBContext.newInstance("mil.army.security.ts3.jaxb.personnel");

            marshaller = jaxbContext.createMarshaller();

            unmarshaller = jaxbContext.createUnmarshaller();

        }

        catch (JAXBException jaxbE) {

            System.err.println("PersonTransformer.PersonTransformer(): JAXBException: " + jaxbE);

            jaxbE.printStackTrace();

        }

    }

}



The blueprint deployment descriptor:



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

<blueprint

        xmlns="http://www.osgi.org/xmlns/blueprint/v1.0.0"

        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

        xmlns:jaxws="http://cxf.apache.org/blueprint/jaxws"

        xsi:schemaLocation="http://www.osgi.org/xmlns/blueprint/v1.0.0

                    http://www.osgi.org/xmlns/blueprint/v1.0.0/blueprint.xsd

                    http://cxf.apache.org/blueprint/jaxws http://cxf.apache.org/schemas/blueprint/jaxws.xsd">

    <bean id="jaxbTransformer" class="mil.army.security.ts3.jaxb.PersonTransformer"/>

</blueprint>





The bundle is built with maven-bundle-plugin using the following imports and exports:



<Import-Package>

    org.osgi.service.blueprint,

    javax.xml.bind,

    javax.xml.bind.annotation

</Import-Package>

<Export-Package>

    mil.army.security.ts3.jaxb

</Export-Package>





To me, it's such a simple JAXB client that should've had every thing that runtime needs to run it. Unfortunately it failed in ServiceMix. The stacktrace is at the end of this email. Would appreciate help and suggestions.



Thanks,

Gang
