Make sure this filename is potentially unique on a Java classpath, like your usual Java class names. One way to make sure is to use a filename prefix following the same conventions as the `Java package naming conventions <https://docs.oracle.com/javase/tutorial/java/package/namingpkgs.html>`_. In this schema file, define an XML type for your attribute provider configuration format. This type must extend ``AbstractAttributeProvider`` from namespace ``http://authzforce.github.io/xmlns/pdp/ext/3``.

In this example, the XSD filename is ``org.ow2.authzforce.core.test.xsd`` and the defined XML type extending ``AbstractAttributeProvider`` is ``TestAttributeProvider``.

#. Run Maven ``generate-sources``. This will generate the JAXB-annotated class(es) from the XML schema into the folder ``target/generated-sources/xjc``, one of which corresponds to your attribute provider XML type defined in the second step, therefore has the same name and also extends ``org.ow2.authzforce.xmlns.pdp.ext.AbstractAttributeProvider`` class corresponding to ``AbstractAttributeProvider`` type in the XML schema. For example, in the case of the Authzforce *Test Attribute Provider* aforementioned, the corresponding generated class is ``org.ow2.authzforce.core.xmlns.test.TestAttributeProvider``. In your case and in general, we will refer to it as your *Attribute Provider Model Class*.
#. Create your Attribute Provider factory and concrete implementation class (as in the *Factory* design pattern). The factory class must be public, and extend ``org.ow2.authzforce.core.pdp.api.CloseableAttributeProviderModule.FactoryBuilder<APM>``, where ``APM`` stands for your *Attribute Provider Model Class*; and the factory class must have a public no-argument constructor or no constructor. You may use the `AuthzForce TestAttributeProviderModule class <https://github.com/authzforce/core/blob/release-5.0.2/src/test/java/org/ow2/authzforce/core/test/custom/TestAttributeProviderModule.java>`_ (used for AuthzForce unit tests only) as an example. In this example, the static nested class ``Factory`` is the one extending ``CloseableAttributeProviderModule.FactoryBuilder<TestAttributeProvider>``. Such a class has a factory method ``getInstance(APM configuration)`` (``getInstance(TestAttributeProvider conf)`` in the example) that, from an instance of your ``APM`` representing the XML input (``TestAttributeProvider`` in the example), creates an instance of your Attribute Provider implementation class (``TestAttributeProviderModule`` in the example). Indeed, your Attribute Provider implementation class must implement the interface ``CloseableAttributeProviderModule`` (package ``org.ow2.authzforce.core.pdp.api``). To facilitate the implementation process, instead of implementing this interface directly, you should extend ``BaseAttributeProviderModule`` (same package) in your implementation class, whenever possible. This class already implements the required interface. There are cases where it is not possible; for instance, since ``BaseAttributeProviderModule`` is an abstract class, if your implementation needs to extend another abstract class, you have no choice but to implement the interface directly, because a Java class cannot extend multiple abstract classes. In any case, as mandated by the interface, your implementation class must implement the method ``get(attributeGUID, attributeDatatype, context))`` in charge of actually retrieving the extra attributes (``TestAttributeProviderModule#get(...)`` in the example). The ``attributeGUID`` identifies an XACML attribute category, ID and Issuer that the PDP is requesting from your attribute provider; the ``attributeDatatype`` is the expected attribute datatype; and ``context`` is the request context, including the content from the current XACML Request and possibly extra attributes retrieved so far by other Attribute Providers.

Indeed, your Attribute Provider implementation class must implement the interface ``CloseableDesignatedAttributeProvider`` (package ``org.ow2.authzforce.core.pdp.api``).

Integrating an Attribute Provider into AuthzForce Server

This section assumes you have an Attribute Provider extension in form of a JAR, typically produced by the process in the previous section. You may use AuthzForce PDP Core Tests JAR if you only wish to test the examples in this documentation.

The steps to integrate the extension into the AuthzForce Server go as follows:
#. Make the JAR - and any extra dependency - visible from the AuthzForce webapp in Tomcat. One way to do it consists to copy the JAR (e.g. ``authzforce-ce-core-5.0.2-tests.jar`` in our example) into ``/opt/authzforce-ce-server/webapp/WEB-INF/lib``. For other ways, please refer to `Tomcat HowTo <http://wiki.apache.org/tomcat/HowTo#How_do_I_add_JARs_or_classes_to_the_common_classloader_without_adding_them_to_.24CATALINA_HOME.2Flib.3F>`_.

For example, in the `sample XML catalog from Authzforce source code <https://github.com/authzforce/server/blob/release-5.4.1/webapp/src/test/server.conf/authzforce-ce/catalog.xml>`_, we add the following line for Authzforce ``TestAttributeProvider``:
