OpenSAML user discussion

[Manuela Stanica <>]

Hi,

have you registered the object providers for your new saml2 objects and 
their corresponding builder, marhaller and unmarshaller in the 
org.opensaml.Configuration class?
In your case it could look similar to:

Configuration.registerObjectProvider(XACMLAuthzDecisionQuery.DEFAULT_ELEMENT_NAME, 
new XACMLAuthzDecisionQueryBuilder(), new 
XACMLAuthzDecisionQueryMarshaller(), new 
XACMLAuthzDecisionQueryUnmarshaller(), null);

(and same for XACMLAuthzDecisionQueryType).

I've also needed to build extensions to the saml2 library, and it all 
worked when just adding these lines before code that uses the new objects.

Hope this helps (?)

Cheers,
Manuela
