Hi,

 

Thanks. This API allows only string to be set as value of attribute. But really the attribute value can be any Java object that is serializable, right?

Subject: [OpenSAML] Attribute Values in XACMLAuthzQuery

Hi Rachana,

I see that my guide is wrong on that point. I made a attribute value like it done in saml, but in saml the attribute value is defined like this

<element name="AttributeValue" type="anyType" nillable="true"/>

But in xacml like this

<xs:element name="AttributeValue" type="xacml-context:AttributeVa

lueType"/>
<xs:complexType name="AttributeValueType" mixed="true">
 <xs:sequence>
 <xs:any namespace="##any" processContents="lax" minOccurs="0"
 maxOccurs="unbounded"/>
 </xs:sequence>
 <xs:anyAttribute namespace="##any" processContents="lax"/>
 </xs:complexType>

So the correct way of creating a attribute value is like this

AttributeValueTypeImplBuilder attributeValueBuilder = (AttributeValueTypeImplBuilder) builderFactory
        .getBuilder(AttributeValueType.DEFAULT_ELEMENT_NAME);

    AttributeValueType actionAttributeValue = attributeValueBuilder
        .buildObject();

    actionAttributeValue.setValue(actionString);

Then the output is correct

 <xacml-context:Attribute AttributeId="urn:action" Issuer="issuer">
         <xacml-context:AttributeValue>action</xacml-context:AttributeValue>
      </xacml-context:Attribute>
