[jboss-dev-forums] [Design of JBossXB] - Marshalling an AbstractKernelDeployment

I've been trying to marshal an AbstractKernelDeployment without success: AbstractKernelDeployment deployment = new AbstractKernelDeployment(); | AbstractBeanMetaData beanMetaData = new AbstractBeanMetaData(); | beanMetaData.setBean(Test.class.getName()); | beanMetaData.setName("test"); | List<BeanMetaDataFactory> beanFactories = new ArrayList<BeanMetaDataFactory>(); | beanFactories.add(beanMetaData); | deployment.setBeanFactories(beanFactories); | MarshallerImpl marshaller = new MarshallerImpl(); | SchemaBindingResolver resolver = SingletonSchemaResolverFactory.getInstance().getSchemaBindingResolver(); | marshaller.setSchemaResolver(resolver); | StringWriter writer = new StringWriter(); | | URL url = Test.class.getClassLoader().getResource("schema/bean-deployer_2_0.xsd"); | | marshaller.marshal(url.toString(), null, deployment, writer); I'm getting this exception: Exception in thread "main" org.jboss.xb.binding.JBossXBRuntimeException: Missing value for the required attribute bean of element {urn:jboss:bean-deployer:2.0}lazy | at org.jboss.xb.binding.sunday.marshalling.DefaultAttributeMarshaller.marshalValue(DefaultAttributeMarshaller.java:89) | at org.jboss.xb.binding.sunday.marshalling.AbstractAttributeMarshaller.marshal(AbstractAttributeMarshaller.java:39) | at org.jboss.xb.binding.sunday.marshalling.MarshallerImpl.marshalComplexType(MarshallerImpl.java:547) | at org.jboss.xb.binding.sunday.marshalling.MarshallerImpl.marshalElementType(MarshallerImpl.java:430) | at org.jboss.xb.binding.sunday.marshalling.MarshallerImpl.marshalElement(MarshallerImpl.java:329) | at org.jboss.xb.binding.sunday.marshalling.MarshallerImpl.marshalElementOccurence(MarshallerImpl.java:309) | at org.jboss.xb.binding.sunday.marshalling.MarshallerImpl.marshallInternal(MarshallerImpl.java:215) | at org.jboss.xb.binding.sunday.marshalling.MarshallerImpl.marshal(MarshallerImpl.java:150) | at org.jboss.microcontainer.tools.Test.main(Test.java:69) Debugging the code, I see that MarshallerImpl (lines 211-216) marshals the deployment by iterating through the ElementBindings and marshalling the ocurrences of each of one those elements: while(elements.hasNext()) | { | ParticleBinding element = elements.next(); | ctx.particle = element; | marshalElementOccurence((ElementBinding) element.getTerm(), root, true, true); | } It seems that at some point, between the marshalElementOcurrence() call and the execution of marshalComplexType(), MarshallerImpl assumes that the element at the stack is a lazy element instead of a deployment element. Given that it isn't, MarshallerImpl fails to find the value of the mandatory bean attribute of lazy and throws the exception above. Taking a look at XsdBinder (lines 476-483), I see that it binds the schema elements with a minOcurrences of 1: XSNamedMap elements = model.getComponents(XSConstants.ELEMENT_DECLARATION); | if (trace) | log.trace("Model elements: " + types.getLength()); | for(int i = 0; i < elements.getLength(); ++i) | { | XSElementDeclaration element = (XSElementDeclaration)elements.item(i); | bindElement(element, 1, 0, false); | } I'm not sure if this has something to do with the problem or not, but it looks weird from my point of view. So, am I doing this the wrong way? Or is this a bug? View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4233925#...
