[jboss-user] [Microcontainer] - What is the correct time to invoke the getProperties on a Be

[jaikiran]

I am trying to dynamically create and deploy an MC bean as follows:

// My MC bean
  | public class MyBean
  | {
  | 
  |   // the attributes especially the bean name will be dynamically modified
  |    @Inject 
  |    private MyOtherBean otherBean;
  | 
  | // other stuff
  | }
  | 

// The code which creates instances of these MyBean and deploys it into MC
  | 
  | BeanMetaDataBuilder builder = BeanMetaDataBuilder.createBuilder("someuniquename", "org.myapp.MyBean");
  | MyBean bean = new MyBean();
  | builder.setConstructorValue(bean);
  | 
  | // Now let's get the PropertyMetadata from the bean (i.e. the @Inject property "otherBean")
  | Set<PropertyMetaData> propertiesOnMyBean = builder.getBeanMetaData().getProperties();
  | 
  | 

The property metadata is always null. Isn't this the right time to call the builder.getBeanMetaData().getProperties()?


The reason i need this information is that i want to dynamically change some attributes of @Inject for the "otherBean" - something on these lines dynamically : 

Set<PropertyMetaData> propertiesOnNoInterfaceMCBean = builder.getBeanMetaData().getProperties();
  | for (PropertyMetaData propertyMetadata : propertiesOnNoInterfaceMCBean)
  | {
  | 	AnnotationMetaData anm = new AbstractAnnotationMetaData(Inject.class.getName());
  |         if (propertyMetadata.getAnnotations().contains(anm) && propertyMetadata.getType().equals(MyOtherBean.class.getName()))
  | 	{
  | 		logger.info("Changing Inject " + propertyMetadata.getName());
  | 		// notice the bean name that we are adding to the @Inject is dynamic
  | 		ValueMetaData inject = builder.createInject("dynamicBeanName", null, null, ControllerState.DESCRIBED);
  | 		// addPropertyMetaData replaces the property metadata (if any)
  | 		builder.addPropertyMetaData(propertyMetadata.getName(), inject);
  | 
  | 		break;
  | 	}
  | }
  | 
  |
