Hibernate: programmatically bind UserTypes to components

I have several different UserTypes (org.hibernate.usertype.UserType) on the system. In this question I will focus on the fact that we are using the DateTime and its UserType, PersistentDateTime.

I have successfully linked the UserType programmatically to the PersistentClass with:

public void customize(Ejb3Configuration config) {

Iterator<PersistentClass> itr = config.getClassMappings();
   while(itr.hasNext()) {
       PersistentClass persistentClass = itr.next();
       for(Iterator<Property> iter = persistentClass.getPropertyIterator(); iter.hasNext();) {
           if(property.getType().getReturnedClass().equals(DateTime.class)) {
               SimpleValue original = (SimpleValue) property.getValue();
               SimpleValue value = new SimpleValue(original.getTable());
               value.setTypeName("org.joda.time.contrib.hibernate.PersistentDateTime");
               value.setTypeParameters(new Properties());
               value.setNullValue(original.getNullValue());

               Iterator<Column> colIter = original.getColumnIterator();
               while(colIter.hasNext())
                   value.addColumn(colIter.next());

               property.setValue(value);
           }

       }
   }
}

      

        
        
        
      

    

The above code is WORKS ... but not for Components that are not instances of PersistentClass. I tried the following code for handling components ... but it does NOT work when it really feels like it should.

public void customize(Ejb3Configuration config) {

Iterator<PersistentClass> itr = config.getClassMappings();
   while(itr.hasNext()) {
       PersistentClass persistentClass = itr.next();
       for(Iterator<Property> iter = persistentClass.getPropertyIterator(); iter.hasNext();) {
           Property property = iter.next();
           if(property.getType().getReturnedClass().equals(DateTime.class)) {
               SimpleValue original = (SimpleValue) property.getValue();
               SimpleValue value = new SimpleValue(original.getTable());
               value.setTypeName("org.joda.time.contrib.hibernate.PersistentDateTime");
               value.setTypeParameters(new Properties());
               value.setNullValue(original.getNullValue());

               Iterator<Column> colIter = original.getColumnIterator();
               while(colIter.hasNext())
                   value.addColumn(colIter.next());

               property.setValue(value);
           } else if (property.getValue() instanceof Component) {
               Component c = (Component)property.getValue();
               for(Iterator<Property> cIt= c.getPropertyIterator(); cIt.hasNext();) {
                    Property cProperty = cIt.next();
                    if(cProperty.getType().getReturnedClass().equals(DateTime.class)) {
                         SimpleValue original = (SimpleValue) cProperty.getValue();
                         SimpleValue value = new SimpleValue(original.getTable());
                         value.setTypeName("org.joda.time.contrib.hibernate.PersistentDateTime");
                         value.setTypeParameters(new Properties());
                         value.setNullValue(original.getNullValue());

                         Iterator<Column> colIter = original.getColumnIterator();
                         while(colIter.hasNext())
                             value.addColumn(colIter.next());

                         cProperty.setValue(value);
                    }
               }

           }

       }
}

      

        
        
        
      

    

I've tried tracking through hibernate code. Hibernate seems to somehow handle components differently than PersistentClasses, but I can't figure out how. My code above seems to set the typeName correctly on the bean property, but hibernate never uses the custom type PersistentDateTime when DateTime is used inside the @Embeddable bean. Of course if I add @Type annotation everything works. I don't want to add this annotation. I want to be able to bind UserType programmatically for Components just like PersistentClasses.

Any ideas?

Thanks!
