OpenSAML user discussion

[Thomas <>]

Hello,

	I'm trying to validate an SAML document I made with opensaml library (2.0  
trunk java version) but I'm getting a NullPointerException during the  
process.
        Here is the code I'm using:


...
unmarshaller = factory.getUnmarshaller( assertionRoot );
assertion = unmarshaller.unmarshall( assertionRoot );
validatorSuite =  
Configuration.getValidatorSuite( "saml2-core-schema-validator" );
validatorSuite.validate( assertion );
...


        The exception I get is:


Exception in thread "main" java.lang.NullPointerException
        at  
org.opensaml.xml.validation.ValidatorSuite.validate(ValidatorSuite.java:83)
        at  
org.opensaml.xml.validation.ValidatorSuite.validate(ValidatorSuite.java:84)
        at Test.validate(Test.java:362)
        at Test.main(Test.java:75)


	I'm trying to validate the attached SAML document, but also with a  
simpler document (with only the elements assertion, issuer and subject) I  
get the same error. Do I need to configure a different validator suite?  
And do I need to make a validator for the attributeValue and ds:keyInfo  
elements? Thanks for your help.
