Note: If a request is made to /barspace/foo.action, the action foo will be searched for in a namespace of /barspace. If the action is not found, the action will then be searched for in the default namespace. Unless specified, the default namespace will be "". In our example above, their is no action foo in the namespace /barspace, therefore the default will be searched and /foo.action will be executed.

Note: Namespace is only one level. For example if the url '/barspace/myspace/bar.action' is requested, Webwork will try to search for namespace '/barspace/myspace', which does not exist in this case, and will fall back to the default namespace '' and tried the search for action with 'bar' alias. As a result the bar action in the default will be used.
