Data connector defined in native Spring

[Petr Medek (DHL IT Services)]

Hello

I have developed custom data connector for some Idp attributes. I use my own parser and definition in attribute-resolver.xml through resolver:DataConnector and it works fine.
Now I want to extend this connector and inject some Spring beans into the connector. According to documentation at https://wiki.shibboleth.net/confluence/display/IDP30/3.+Developing+Attribute+Resolver+Extensions#id-3.DevelopingAttributeResolverExtensions-NativeSpringConfiguration it should be possible to define the connector as spring bean and use it in attribute-resolver.xml.
So I removed my resolver:DataConnector element from attribute-resolver.xml and configured spring bean with the same name in global.xml.
The attribute using this data connector is defined like:

    <resolver:AttributeDefinition xsi:type="ad:Simple" id="action" sourceAttributeID="umAction">
            <resolver:Dependency ref="umConn" />
            <resolver:AttributeEncoder xsi:type="enc:SAML2String" name="urn:oid:1.3.6.1.4.1.5923.1.5.1.1" friendlyName="action" encodeType="false" />
    </resolver:AttributeDefinition>

and my spring bean is:

<bean id="umConn" class="com.dhl.shibboleth.dc.UmRolesDataConnector">
...
</bean>

However when Shibboleth starts the attribute definition is wrong with message in idp-warning.log:

2016-03-08 15:14:59,635 - ERROR [net.shibboleth.utilities.java.support.service.AbstractReloadableService:181] - Service 'shibboleth.AttributeResolverService': Initial load failed

2016-03-08 15:15:01,016 - ERROR [net.shibboleth.idp.saml.metadata.impl.AttributeMappingNodeProcessor:144] - Requested Attributes Mapper: Invalid Attribute resolver configuration.

So what I missed from the wiki page? Do I need to use different file than global.xml or this native spring definition works in some other way?
I'm using IDP 3.1.1.

Thanks for any hint
Petr
