Are you saying you're getting null from obtaining an Attribute builder from the builder factory?  Or for all objects?   Or that you're getting an NPE somewhere else?

Note that in the example on that page Chad sent, the building of the Attribute isn't shown, you have to do that before you call attribute.getAttributeValues(), just like any other XMLObject.  The purpose of the page is to show the use of the XSAny provider for special cases.

However, in your original question, you used an AttributeType, which the provider interface for a XACML attribute.  Is that what you wanted, or did you want SAML Attribute?

Thanks, that seems applicable only to the AttributeValue to add. I have that
fixed to use builder of the type. 

But, in the example on that webpage, how is this built?

// Normally built Attribute object
Attribute attribute;

The NPE I am seeing is with building the Attribute object, not the
AttributeValue.  

If there are samples I should look at, I would appreciate a pointer.

Thanks,
Rachana

Hi,

I have the following code to create attributes with some 
      

string value, but
    

end up with AttributeTypeImplBuilder ends up being null.

Here are relevant code snippets:

import org.opensaml.Configuration;
static XMLObjectBuilderFactory builderFactory;
    static {
        try {
            org.opensaml.DefaultBootstrap.bootstrap();
        } catch (Exception e) {
            // FIXME: handle exception better
            System.err.println(e);
        }
        builderFactory = Configuration.getBuilderFactory();
        System.out.println("Builder factory " + 
      

(builderFactory == null));
    

    }

// attribute builder is null here.
AttributeTypeImplBuilder attributeBuilder = 
      

(AttributeTypeImplBuilder)
    

 
builderFactory.getBuilder(AttributeType.DEFAULT_ELEMENT_NAME);

Is there any additional initialization that is required? 

Thanks,
Rachana
