Portlet Application Deployment Descriptor - Events

Use to create and manage portlet events for the portlets in the application. Portlet events enable interportlet communication.

Element Description

Name

Add

Click to create a new portlet event in the application.

Remove

Click to delete the currently selected portlet event.

Qualified Name/ Unqualified Name

Select whether the portlet event has a qualified or unqualified name.

Qualified Name

Select to specify a fully qualified name (QName) for the portlet event. A QName consists of a namespace URI and a local part and provides a unique identifier for the event. Using QNames ensures that the portlet event names from this application do not conflict with portlet events from other applications when portlets from different applications are displayed on the same page.

  • Namespace

    Enter the namespace for the selected portlet event.

  • Name

    Enter a local name for the selected portlet event.

Unqualified Name

Select to use the application default namespace as the namespace for the portlet event (or the XML default namespace if no default namespace is defined for the application).

  • Name

    Enter a local name for the selected portlet event.

Payload Type

Enter or browse for the data type of the payload provided by the selected portlet event.

Description

Enter a description for the selected portlet event.

Aliases

Use this panel to provide aliases for the portlet event. If a portlet triggers an event that does not match the QName of this event, but does match one of its aliases, the event handler renames the event, meaning that a portlet that consumes this event can still receive the payload from the triggered event.

Add

Click to create an alias for the selected portlet event.

  • Namespace

    Enter the namespace to use for the alias.

  • Name

    Enter the local name to use for the alias.

Remove

Click to delete the currently selected alias.
