Interface Auth2SchemeFactory

public interface Auth2SchemeFactory

Classes that implement this interface provide Qwicap with instances of Auth2Scheme, which supply authentication & authorization (Auth²) functionality. An authentication & authorization scheme is associated with a Qwicap web application by an entry in its "web.xml" file, for example:

<web-app>
    ....
    <servlet>
        ....
        <init-param>
            <param-name>QwicapAuth2SchemeFactoryClassName</param-name>
            <param-value>edu.utexas.its.eis.tools.fatcookie.qwicap.FatCookieAuth2SchemeFactory</param-value>
        </init-param>
        ....
    </servlet>
    ....
</web-app>

In other words, include within the "servlet" element an "init-param" element containing a "param-name" element of "QwicapAuth2SchemeFactoryClassName" and a "param-value" element that specifies the fully-qualified name of the class that implements the Auth2SchemeFactory interface.

If the web application doesn't need to acquire any information about the user from its associated Auth2Scheme, then that's all there is to it; the web app doesn't even need to know that it has an Auth2Scheme.
