Under seam one name component like @Name("org.acme.components.SuperAction") and then use an import statement in components.xml like <import>org.acme.components</import>.
This allows the views to use "SuperAction" without the full name. It's a nice feature as it stops component developers from polluting the namespace, but still allows users to use a simple name for the action.
This works OK for basic Seam components, but not for EJB3 components. For these the import declaration seems to be ignored.
