I am doing a SOAP call to set the "featured" additional attribute to "1", but it is not being stored by Magento.
Here is the relevent part of my Java code:
CatalogProductCreateEntity data = new CatalogProductCreateEntity();
AssociativeEntity attribute = new AssociativeEntity();
attribute.setKey("featured");
attribute.setValue("1");
AssociativeArray associativeArray = new AssociativeArray();
associativeArray.getComplexObjectArray().add(attribute);
data.setAdditionalAttributes(associativeArray);
