Chapter 30. Built-in Seam components
This chapter describes Seam's built-in components, and their configuration properties. The built-in components are created automatically, even if they are not listed in your
components.xml
file. However, if you need to override default properties or specify more than one component of a certain type, you can do so in components.xml
.
You can replace any of the built-in components with your own implementation by using
@Name
to name your own class after the appropriate built-in component.
30.1. Context injection components
The first set of built-in components support the injection of various contextual objects. For example, the following component instance variable would have the Seam session context object injected:
@In private Context sessionContext;
-
org.jboss.seam.core.contexts
- Component that provides access to Seam Context objects such as
org.jboss.seam.core.contexts.sessionContext['user']
. -
org.jboss.seam.faces.facesContext
- Manager component for the
FacesContext
context object. (This is not a true Seam context.)
All of these components are always installed.
