Hi All,

 

I’m implementing a UserFederationProviderFactory and want to create an EntityManagerFactory from one of its methods.  I have packaged up a persistence.xml in the META-INF folder of the SPI jar file and deployed this as a module to the keycloak standalone server. 

 

My module.xml looks like this…

 

<module xmlns="urn:jboss:module:1.3" name="acme.keycloak-acme-user-federation">

    <resources>

        <resource-root path="keycloak-acme-user-federation-1.0.0.jar">

            <filter>

                <include path="META-INF/**"/>

            </filter>

        </resource-root>

    </resources>

    <dependencies>

        <module name="org.keycloak.keycloak-core"/>

        <module name="org.keycloak.keycloak-server-spi"/>

        <module name="javax.api"/>

        <module name="javaee.api"/>

        <module name="org.hibernate" />

        <module name="org.jboss.ws.cxf.jbossws-cxf-client"/>

    </dependencies>

 

</module>

 

In my UserFederationProviderFactory I have a method like this…

 

                private EntityManagerFactory getEntityManagerFactory(UserFederationProviderModel model) {

                                if (emf == null) {

                                                logger.trace("Creating entityManagerFactory...");

                                                Map<String, String> config = model.getConfig();

                                                Properties p = new Properties();

                                                // for now just use hibernate built in connection factory

                                                p.put("hibernate.connection.driver_class", config.get(DATABASE_DRIVER_CLASS_NAME));

                                                p.put("hibernate.connection.url", config.get(DATABASE_URL));

                                                p.put("hibernate.connection.username", config.get(DATABASE_USER));

                                                p.put("hibernate.connection.password", config.get(DATABASE_PASSWORD));

                                                p.put("hibernate.show_sql", "true");

                                                p.put("hibernate.format_sql", "true");

                                                emf = Persistence.createEntityManagerFactory("acmeEntities", p);

                                }

                               

                                return emf;

                }

 

When this method is called, it always returns the error “No Persistence provider for EntityManager named acmeEntities”.

 

I’m 90% sure this is to do with the ClassLoader being used by Persistence not being able to see the META-INF/persistence.xml packaged up in the keycloak-acme-user-federation-1.0.0.jar.  Does anyone have an idea what I need to do to my module configuration to get this working?

 

Thanks,
