Sometimes its is desirable to test your actions outside the container see Testing Actions for details.

If you use JSPs as the template engine you won't be able to test the action output outside the container. The Embedded JSP Plugin can be used to overcome this limitation and be able to use JSPs from the classpath and outside the container.
