Moxy error with Karaf

Question

I'm using MOXy under fuse ESB (based on karaf), I converted org.eclipse.persistence.jar to a bundle, I deployed this bundle under fuse ESB and I got this error

Error : "org.apache.cxf.interceptor.Fault: property "eclipselink-oxm-xml" is not supported"

When trying to create new instance of JAXBContextmy code is trying to convert Java model to XML, and the model is deployed in a separate bundle under fuse ESB and I added jaxb.properties file in the same package of the model

Note: The same code runs successfully without problems when running from a main method in a main class.

The following is my code and the error happens at line no.6.

    Map<String, Source> metadataSourceMap = new HashMap<String, Source>();      
    InputStream is = getClass().getClassLoader().getResourceAsStream
            ("com/syngenta/mint/security/service/transformation/User.xml");             

    metadataSourceMap.put("com.syngenta.mint.security.model",new StreamSource(is));

    1. Map<String, Object> properties = new HashMap<String, Object>();
    2. properties.put(JAXBContextFactory.ECLIPSELINK_OXM_XML_KEY,
            metadataSourceMap);
    3. properties.put("javax.xml.bind.context.factory",
                 "org.eclipse.persistence.jaxb.JAXBContextFactory");

    4. Class[] classes = new Class[1];
    5. classes[0] = User.class;

    6. JAXBContext jc = JAXBContext.newInstance(classes, properties);

Any Idea?

Answer 1

Instead of converting eclipselink.jar to a bundle, you can download our pre-built OSGi bundles from the following location:

EclipseLink 2.4.1 Bundles

• http://www.eclipse.org/downloads/download.php?file=/rt/eclipselink/releases/2.4.1/eclipselink-plugins-2.4.1.v20121003-ad44345.zip

For EclipseLink JAXB (MOXy) you will need the following bundles:

• org.eclipse.persistence.moxy_2.4.1.v20121003-ad44345.jar
• org.eclipse.persistence.core_2.4.1.v20121003-ad44345.jar
• org.eclipse.persistence.asm_3.3.1.v201206041142.jar

If you are using MOXy's JSON binding (see: http://blog.bdoughan.com/2011/08/json-binding-with-eclipselink-moxy.html) you will also need the following bundle:

• org.eclipse.persistence.antlr_3.2.0.v201206041011.jar

UPDATE #1

In an OSGi environment you will need to ensure that you import either the MOXy bundle, or the org.eclipse.persistence.jaxb packages.

another question in my code above at line 2, I found that JAXBContextFactory.ECLIPSELINK_OXM_XML_KEY is deprecated in the eclipse bundles that you mentioned in your answer, is there any replacement for it?

We have introduced new classes to make it easier to find the properties on JAXBContext, Marshaller, and Unmarshaller. These classes are called JAXBContextProperties, MarshallerProperties, and UnmarshallerProperties and can be found in the org.eclipse.persistence.jaxb package.

• The following: JAXBContextFactory.ECLIPSELINK_OXM_XML_KEY
• Is replaced by: JAXBContextProperties.OXM_METADATA_SOURCE

UPDATE #2

I haven't used Karaf, but below is an OSGi example I'm able to run in Eclipse Equinox:

example/Activator.java

I find you need to create the JAXBContext using a context path. This allows you to pass in a ClassLoader. This class loader needs to be aware of the EclipseLink JAXB (MOXy) implementation. I've also included an example of specifying MOXy's external mapping document.

package example;

import java.util.*;
import javax.xml.bind.*;
import org.eclipse.persistence.jaxb.JAXBContextProperties;
import org.osgi.framework.*;

public class Activator implements BundleActivator {

    private static BundleContext context;

    static BundleContext getContext() {
        return context;
    }

    public void start(BundleContext bundleContext) throws Exception {
        Activator.context = bundleContext;

        Map<String, Object> properties = new HashMap<String, Object>(1);
        properties.put(JAXBContextProperties.OXM_METADATA_SOURCE,
                "example/oxm.xml");
        JAXBContext jc = JAXBContext.newInstance("example",
                Customer.class.getClassLoader(), properties);

        Customer customer = new Customer();
        customer.setName("Jane Doe");

        Marshaller marshaller = jc.createMarshaller();
        marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true);
        marshaller.marshal(customer, System.out);
    }

    public void stop(BundleContext bundleContext) throws Exception {
        Activator.context = null;
    }

}

example/jaxb.index

When creating a JAXBContext from a context path you need to include a file called jaxb.index in the context path with a carriage return separated list of short class names.

Customer

example/jaxb.properties

To specify MOXy as your JAXB provider you need to include a file called jaxb.properties in the same package as your domain model with the following entry:

javax.xml.bind.context.factory=org.eclipse.persistence.jaxb.JAXBContextFactory

example/oxm.xml

Below is an example MOXy mapping document.

<?xml version="1.0" encoding="UTF-8"?>
<xml-bindings
    xmlns="http://www.eclipse.org/eclipselink/xsds/persistence/oxm"
    package-name="example">
    <java-types>
        <java-type name="Customer">
            <xml-root-element/>
             <java-attributes>
                <xml-element java-attribute="name" xml-path="personal-info/name/text()"/>
            </java-attributes>
        </java-type>
    </java-types>
</xml-bindings>

META-INF/MANIFEST.MF

Below is an example of the manifest. In this example I have used bundle imports:

Manifest-Version: 1.0
Bundle-ManifestVersion: 2
Bundle-Name: Example
Bundle-SymbolicName: Example
Bundle-Version: 1.0.0.qualifier
Bundle-Activator: example.Activator
Import-Package: org.osgi.framework;version="1.3.0"
Bundle-RequiredExecutionEnvironment: JavaSE-1.6
Require-Bundle: org.eclipse.persistence.antlr,
 org.eclipse.persistence.asm,
 org.eclipse.persistence.core,
 org.eclipse.persistence.moxy,
 javax.xml.bind

Output

Below is the output from running the Activator:

<?xml version="1.0" encoding="UTF-8"?>
<customer>
   <personal-info>
      <name>Jane Doe</name>
   </personal-info>
</customer>

Answer 2

the problem has been solved by replacing this piece of code

Map<String, Source> metadataSourceMap = new HashMap<String, Source>();      
InputStream is = getClass().getClassLoader().getResourceAsStream("com/syngenta/mint/security/service/transformation/User.xml");               metadataSourceMap.put("com.syngenta.mint.security.model",new StreamSource(is));
Map<String, Object> properties = new HashMap<String, Object>();
properties.put(JAXBContextFactory.ECLIPSELINK_OXM_XML_KEY,metadataSourceMap);
        properties.put("javax.xml.bind.context.factory","org.eclipse.persistence.jaxb.JAXBContextFactory");

With

InputStream is = getClass().getClassLoader().getResourceAsStream("com/syngenta/mint/security/service/transformation/User.xml");    
Map<String, Object> properties = new HashMap<String, Object>();
properties.put(JAXBContextProperties.OXM_METADATA_SOURCE, is);
