I think the problem might be that the JAXbContext uses the wrong
classloader.
Can you try to give the JAXBContext the classloader that has access to
the Person class?
Bundle bundle = bundleContext.getBundle();
BundleWiring bundleWiring = bundle.adapt(BundleWiring.class);
ClassLoader classLoader = bundleWiring.getClassLoader();
jaxbContext =
JAXBContext.newInstance("mil.army.security.ts3.jaxb.personnel",
classloader);
Another thing you could try is to specify the classes directly. This
completely avoids issues with the classloader:
jaxbContext = JAXBContext.newInstance(Person.class);

Hi, Krzysztof,
Thanks for the response. I've tried this configuration thinking to make the
JAXB package also visible to the outside and I just tried it again now. It did
not work.

Subject: Re: Simple JAXB client doesn't work in ServiceMix
Hi
Could you try following definition for export packages?
<Export-Package>
mil.army.security.ts3.jaxb.*
</Export-Package>
or
<Export-Package>
mil.army.security.ts3.jaxb.personnel
</Export-Package>
Regards
Krzysztof

Hi,
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="<thismessage:/>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
