OpenSAML user discussion

[Brent Putman <>]

Ok, then the link Chad sent you is irrelevant, your original code with the AttributeType is what you want.

Sounds like you just have an older version of the opensaml jar file.  The XACML stuff was included in the library only with the 2.1.0 release.  Your opensaml jar should have the following config files, if it doesn't, it's too old.

#:  jar tvf opensaml-2.1.0.jar | grep 'config\.xml' | cut -c 37-

saml1-assertion-config.xml
saml1-core-validation-config.xml
saml1-metadata-config.xml
saml1-protocol-config.xml
saml2-assertion-config.xml
saml2-core-validation-config.xml
saml2-metadata-config.xml
saml2-metadata-query-config.xml
saml2-metadata-validation-config.xml
saml2-protocol-config.xml
saml2-protocol-thirdparty-config.xml
xacml10-saml2-profile-config.xml
xacml11-saml2-profile-config.xml
xacml2-saml2-profile-config.xml
xacml20-context-config.xml
xacml20-policy-config.xml
xacml3-saml2-profile-config.xml


In 2.1.0 all of these, including the XACML ones, are loaded by the standard DefaultBootstrap.bootstrap().

Hi,

 

Yes, Attribute builder is null and I am trying to get an XACML attribute. I am able to get the following correctly, so it is not all objects, might just be XACML namespace.

 

XSStringBuilder stringBuilder = (XSStringBuilder)
                builderFactory.getBuilder(XSString.TYPE_NAME);

 

Based on logs, I don't see any registration of builder for Attribute Type. The following initialization code is in place:

 

            org.apache.xml.security.Init.init();
            org.opensaml.DefaultBootstrap.bootstrap();
        builderFactory = Configuration.getBuilderFactory();

 

The factory object gets initialized correctly.

 

Looking at DefaultBootstrap.java, I don't see any xacml*config files loaded for initialization and search for that in source files yielded nothing. The config files are loaded in the OpenSAML jar. Any idea where the xacml config files get loaded from and how I can add that to the initialization?

 

Thanks,

Rachana

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
