Hello,

meanwhile I've changed the Java code that I've presented within my last 
mail. Now I'm trying to retrieve all attribute definitions from 
attribute-resolver.xml by the use of resolution plugin objects:

public Map<String, BaseAttribute> resolve(
    ShibbolethResolutionContext resolutionContext)
    throws AttributeResolutionException
  {
   ...

    Map <String, ResolutionPlugIn> r = 
resolutionContext.getResolvedPlugins();
    Collection<ResolutionPlugIn> values = r.values();

    for (Iterator i = values.iterator(); i.hasNext(); )
    {
      ResolutionPlugIn plugin = (ResolutionPlugIn) i.next();

      if (plugin instanceof DataConnector)
      {
        log.debug("Found DataConnector: " + plugin.getId());
      }

      if (plugin instanceof AttributeDefinition)
      {
        log.debug("Found AttributeDefinition: " + plugin.getId());
      }
    }
   ...
  }

Result:

DEBUG MyShibbolethDataConnector.java(75): Found AttributeDefinition: 
eduPersonPrincipalName
DEBUG MyShibbolethDataConnector.java(70): Found DataConnector: myShibboleth

As you can see, there is one DataConnector object but only ONE 
AttributeDefinition object found, although I've defined THREE attribute 
definitions in attribute-resolver.xml. Maybe there is a configuration 
error when my BaseDataConnector implementation is initialized or called? 
This is the corresponding xsd:

<?xml version="1.0" encoding="UTF-8"?>
<schema targetNamespace="urn:mace:unikn:shibboleth:resolver"
        xmlns="http://www.w3.org/2001/XMLSchema";
        xmlns:resolver="urn:mace:shibboleth:2.0:resolver"
        elementFormDefault="qualified">

  <import namespace="urn:mace:shibboleth:2.0:resolver"

schemaLocation="classpath:/schema/shibboleth-2.0-attribute-resolver.xsd" />

  <complexType name="MyShibbolethDataConnector">
    <annotation>
      <documentation>
       Description of your data connector.
      </documentation>
    </annotation>
    <complexContent>
      <extension base="resolver:BaseDataConnectorType">
       <attribute name="attr1" type="string" use="optional"/>
      </extension>
    </complexContent>
  </complexType>
</schema>

When I was programming corresponding FactoryBean and NamespaceHandler 
classes, I've followed the example at:

https://spaces.internet2.edu/display/SHIB2/IdPDevExtDataCtr

How can I enable my BaseDataConnector implementation to get all 
attribute definitions?

Best regards,
Markus
