Marshalling attributes as node, why ? [message #521808] Thu, 18 March 2010 14:48 Go to next message

I'm using eclipse link (OSGI version) to read/write an XML file; something like this:

   <node attribute0="some value" attribute1="some other value" />

when I create a marshaller and write the xml file I got its content modified and no longer fit its XSD scheme.
Opening the just created xml file i find attributes as nodes, like this:

       <attribute0>some value</attribute0>
       <attribute1>some other value</attribute1>

this is the code I use to write xml file:

File myXMLFile = new File("/home/myName/myfile.xml");
Root rootNode = myObjectFactory.createRoot();
//...some other lines
//...some try and catch
Marshaller marshaller = jaxbContext.createMarshaller();
marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, Boolean.TRUE);
marshaller.marshal(root, myXMLFile);

The linked class "Node" has properties "attribute0" and "attribute1" as @XmlAttribute

any one can help me ?
many thanks Smile

If you have the following the you should see properties attribute0 & attribute1 marshal as attributes. Can you share your model?

import javax.xml.bind.annotation.XmlAttribute;

public class Node {

    private String attribute0;
    private String attribute1;

    public String getAttribute0() {
        return attribute0;

    public void setAttribute0(String attribute0) {
        this.attribute0 = attribute0;

    public String getAttribute1() {
        return attribute1;

    public void setAttribute1(String attribute1) {
        this.attribute1 = attribute1;

Hi, I have the same issue, I'm using EclipseLink OSGI version 2.0.1.
I have tested with the model you proposed and a blank project, this is the Activator class:
	public void start(BundleContext context) throws Exception
		JAXBContext jaxbContext = null;
		jaxbContext = JAXBContext.newInstance("my.models", new BundleProxyClassLoader(context.getBundle()));

		Node n = new Node();
        // Step 2 - Convert the Domain Model to XML
        Marshaller marshaller = jaxbContext.createMarshaller();
        marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true);
        marshaller.marshal(new ObjectFactory().createNode(n), System.out);

I have found BundleProxyClassLoader somewhere in another user thread to let MOXy find ObjectFactory inside my models package.

This is the output of ss:
Framework is launched.

bundle 8 is my testbundle.

and this is the output:
osgi> <START>
<?xml version="1.0" encoding="UTF-8"?>
<ns0:node xsi:type="node" xmlns:ns0="http://my.models" xmlns:xsi="">

If I use non OSGI version of EclipseLink MOXy the XML output is OK :-\

Uhmm, seems like I have solved my issue ...
I added javax.xml.bind.annotation in, Import-Package section, it appears strange to me since I didn't get class not found error or others problems inspecting the package and its imported packages from osgi console commands.


Smile well hope this help
