Imposed ordering of elements

to follow the new strict order rules Alexey impounded.

The error for one of my tests is:

Caused by: org.jboss.xb.binding.JBossXBRuntimeException: {urn:jboss:aop-beans:1.0}class cannot appear in this posi
tion. Expected content of {urn:jboss:aop-beans:1.0}mixin is sequence: {urn:jboss:aop-beans:1.0}class? {urn:jboss:a
op-beans:1.0}construction? {urn:jboss:aop-beans:1.0}interfaces?
 at org.jboss.xb.binding.sunday.unmarshalling.SundayContentHandler.startElement(SundayContentHandler.java:4
94)

My schema is:

 <xsd:complexType name="mixinType">
 <xsd:annotation>
 <xsd:documentation>
 <![CDATA[
 A mixin within an interface introduction
 ]]>
 </xsd:documentation>
 </xsd:annotation>
 <xsd:all minOccurs="1" maxOccurs="1">
 <xsd:element name="interfaces" type="xsd:string" minOccurs="1" maxOccurs="1" />
 <xsd:element name="class" type="xsd:string" minOccurs="1" maxOccurs="1" />
 <xsd:element name="construction" type="xsd:string" minOccurs="0" maxOccurs="1" />
 </xsd:all>
 <xsd:attribute name="transient" type="xsd:boolean" use="optional"/>
 </xsd:complexType>

So I can only conclude that the order imposed is from the order of the setters in the associated parser class, which truly sucks:

public class MixinData
{
 String mixin;
 boolean isTransient = true;
 String construction;
 String interfaces;

 public boolean getTransient()
 {
 return isTransient;
 }

 @XmlAttribute
 public void setTransient(boolean isTransient)
 {
 this.isTransient = isTransient;
 }

 public String getMixin()
 {
 return mixin;
 }

 @XmlElement(name="class")
 public void setMixin(String mixin)
 {
 this.mixin = mixin;
 }

 public String getConstruction()
 {
 return construction;
 }

 public void setConstruction(String construction)
 {
 this.construction = construction;
 }

 public String getInterfaces()
 {
 return interfaces;
 }

 public void setInterfaces(String interfaces)
 {
 this.interfaces = interfaces;
 }
}

Is there some annotation that can be used on the class to get rid of this imposed ordering?

Doesn't xsd:all mean unordered elements? Any reason why the order is being imposed?

The annotation metada is used as the driving source for jaxb based parsers. The value of propOrder should be set to "{}" when you want xsd:all (unordered) behavior. This is what xjc would have generated.

Coming back to this a number of my tests are failing again. When parsing the following xml

<deployment xmlns="urn:jboss:bean-deployer:2.0">

 <bean name="AspectManager" class="org.jboss.aop.AspectManager">
 <constructor factoryClass="org.jboss.aop.AspectManager" factoryMethod="instance"/>
 </bean>

 <aspect xmlns="urn:jboss:aop-beans:1.0" name="InterceptedAdvice" class="org.jboss.test.microcontainer.support.TestAspect"/> <!-- Line 9 -->

 ...
</deployment>

It falls over with the following exception

This seems to be on first access to anything within the "urn:jboss:aop-beans:1.0" schema, and I believe it is from trying to parse the schema. Here is the top-level class:

@ManagementObject(properties = ManagementProperties.EXPLICIT) // TODO - explicitly add props we want to manage
@JBossXmlSchema(namespace="urn:jboss:aop-beans:1.0", elementFormDefault=XmlNsForm.QUALIFIED)
@XmlRootElement(name="aop")
@XmlType(propOrder={"annotations", "classLoader", "beanFactories", "create", "start", "stop", "destroy", "aliases"})
public class AOPDeployment extends AbstractKernelDeployment
{
 private static final long serialVersionUID = 1L;


 @XmlElements
 ({
 @XmlElement(name="annotation", type=AnnotationOverrideBeanMetaDataFactory.class),
 @XmlElement(name="annotation-introduction", type=AnnotationIntroductionBeanMetaDataFactory.class),
 @XmlElement(name="arrayreplacement", type=ArrayReplacementBeanMetaDataFactory.class),
 //Many more!
 })
 @XmlAnyElement
 public void setBeanFactories(List<BeanMetaDataFactory> beanFactories)
 {
 super.setBeanFactories(beanFactories);
 }
}

AnnotationOverrideBeanMetaDataFactory:

@JBossXmlSchema(namespace="urn:jboss:aop-beans:1.0", elementFormDefault=XmlNsForm.QUALIFIED)
@XmlRootElement(name="annotation")
public class AnnotationOverrideBeanMetaDataFactory extends AbstractAnnotationBeanMetaDataFactory
{

 private static final long serialVersionUID = 1L;

 @Override
 protected String getBeanClassName()
 {
 return AnnotationOverride.class.getName();
 }
}

AbstractAnnotationBeanMetaDataFactory

public abstract class AbstractAnnotationBeanMetaDataFactory extends AspectManagerAwareBeanMetaDataFactory
{
 private static final long serialVersionUID = 1L;

 String expr;

 boolean invisible;

 String annotation;

 public String getExpr()
 {
 return expr;
 }

 @XmlAttribute
 public void setExpr(String expr)
 {
 this.expr = expr;
 }

 public boolean isInvisible()
 {
 return invisible;
 }

 @XmlAttribute
 public void setInvisible(boolean invisible)
 {
 this.invisible = invisible;
 }

 public String getAnnotation()
 {
 return annotation;
 }

 @XmlValue
 public void setAnnotation(String annotation)
 {
 this.annotation = annotation;
 }

 @Override
 public List<BeanMetaData> getBeans()
 {
 ArrayList<BeanMetaData> result = new ArrayList<BeanMetaData>();
 if (name == null)
 {
 name = GUID.asString();
 }
 BeanMetaDataBuilder builder = BeanMetaDataBuilder.createBuilder(name, getBeanClassName());
 builder.addPropertyMetaData("invisible", invisible);
 builder.addPropertyMetaData("expr", expr);
 builder.addPropertyMetaData("annotation", annotation);

 setAspectManagerProperty(builder);

 result.add(builder.getBeanMetaData());

 return result;
 }


 protected abstract String getBeanClassName();
}

AspectManagerAwareBeanMetaDataFactory

public abstract class AspectManagerAwareBeanMetaDataFactory extends GenericBeanFactoryMetaData
{
 //Setters to handle the aspectmanager to add the aop metadata to
}

Then from MC we have GenericBeanFactoryMetaData

@XmlRootElement(name="beanfactory")
@XmlType(name="beanfactoryType", propOrder={"aliases", "annotations", "classLoader", "constructor", "properties", "create", "start", "depends", "demands", "supplies", "installs", "uninstalls", "installCallbacks", "uninstallCallbacks"})
public class GenericBeanFactoryMetaData extends JBossObject implements BeanMetaDataFactory, Serializable
{
 ...
}

If I add @XmlType(propOrder={})to AnnotationOverrideBeanMetaDataFactory:

@JBossXmlSchema(namespace="urn:jboss:aop-beans:1.0", elementFormDefault=XmlNsForm.QUALIFIED)
@XmlRootElement(name="annotation")
@XmlType(propOrder={})
public class AnnotationOverrideBeanMetaDataFactory extends AbstractAnnotationBeanMetaDataFactory
{

 private static final long serialVersionUID = 1L;

 @Override
 protected String getBeanClassName()
 {
 return AnnotationOverride.class.getName();
 }
}

I then get a new error

First, I thought it might be due to the @XmlType set in the AnnotationOverrideBeanMetaDataFactory somehow interfering with the one in its superclass GenericBeanFactoryMetaData.

But it looks more likely that is is due to BeanMetaData which is returned by the AnnotationOverrideBeanMetaDataFactory.getBeans() not having @XmlType(propOrder={})? BeanMetaData is an mc spi interface with no xb annotations. The annotations are on impl classes instead, which is probably how it should be?

If my reasoning is correct, how to get around this?

aloubyansky May 7, 2009 6:34 PM (in response to kabirkhan)

As the error reads, you have to specify property order for org.jboss.aop.microcontainer.beans.metadata.AnnotationOverrideBeanMetaDataFactory.

I don't know why XmlType specified on a super class is not visible.
propOrder={} binds to model group all instead of sequence. Check out the javadoc for XmlType, it has an example and explanation.

The last error says BeanMetaData is missing property order as well.

kabirkhan May 11, 2009 7:28 AM (in response to kabirkhan)

AnnotationOverrideBeanMetaDataFactory passes if I annotate the class with @XmlType(propOrder={}) and the AbstractAnnotationBeanMetaDataFactory.getBeans() method with @XmlTransient.

A few more classes get through when I do this, but I get another error

kabirkhan May 11, 2009 7:52 AM (in response to kabirkhan)

If I annotate my classes with

@XmlRootElement
public class AdviceData extends AdviceOrInterceptorData

This passes

@JBossXmlSchema(namespace="urn:jboss:aop-beans:1.0", elementFormDefault=XmlNsForm.QUALIFIED)

public class ArrayBindBeanMetaDataFactory extends AspectManagerAwareBeanMetaDataFactory

@XmlElements

 @XmlElement(name="advice", type=AdviceData.class)
 })

aloubyansky May 11, 2009 9:58 AM (in response to kabirkhan)

As I mentioned before, @XmlType(propOrder= {}) binds to a model group all (http://www.w3.org/TR/xmlschema-1/#Model_Groups) which can contain only elements (not sequences or choices). Interceptors in your case will be bound to a repeatable choice. See javadoc for XmlElements.
