5.7.2. Registration configuration

To require consumers to register with the Portal's producer before interacting with it, you need to configure the Portal's behavior with respect to registration. Registration is optional, as registration properties. The producer can require registration without passing any registration properties in case of the default configuration. Let's configure our producer starting with a blank state:

eXo Platform will allow unregistered consumers to see the list of offered portlets, so the first checkbox ("Access to full service description requires consumers to be registered") is unchecked. You will, however, specify that consumers will need to be registered to be able to interact with our producer. Check the second checkbox ("Requires registration. Modifying this information will trigger invalidation of consumer registrations."). The screen should now refresh and display:

You can specify the fully-qualified name for your RegistrationPolicy and RegistrationPropertyValidator there. We will keep the default value. See Section 5.7.2, “Registration configuration” for more details. Let's add, however, a registration property called email. Click "Add property" and enter the appropriate information in the fields, providing a description for the registration property that can be used by consumers to figure out its purpose:

Press "Save" to record your modifications.


At this time, only String (xsd:string) properties are supported. If your application requires more complex properties, please let us know.


If consumers are already registered with the producer, modifying the configuration of required registration information will trigger the invalidation of held registrations, requiring consumers to modify their registration before being able to access the producer again. We saw the consumer side of that process in Section 5.6.1, “Modifying a currently held registration”.

Customization of Registration handling behavior

Registration handling behavior can be customized by users to suit their Producer needs. This is accomplished by providing an implementation of the RegistrationPolicy interface. This interface defines methods that are called by Portal's Registration service so that decisions can be made appropriately. A default registration policy that provides basic behavior is provided and should be enough for most user needs.

While the default registration policy provides the default behavior for most registration-related aspects, there is still one aspect that requires configuration: whether a given value for a registration property is acceptable by the WSRP producer. This is accomplished by plugging a RegistrationPropertyValidator in the default registration policy. This allows users to define their own validation mechanism.

Please refer to the Javadoc™ for org.jboss.portal.registration.RegistrationPolicy and org.jboss.portal.Registration.policies.RegistrationPropertyValidator for more details on what is expected of each method.

Defining a registration policy is required for the producer to be correctly configured. This is accomplished by specifying the qualified class name of the registration policy. Since we anticipate that most users will use the default registration policy, it is possible to provide the class name of your custom property validator instead of customizing the default registration policy behavior. Note that property validators are only used by the default policy.


Since the policy or the validator are defined via their class name and dynamically loaded, it is important that you make sure that the identified class is available to the application server. One way to accomplish that is to deploy your policy implementation as the JAR file in your AS instance deploy directory. Note also that, since both policies and validators are dynamically instantiated, they must provide a default, no-argument constructor.
