Introduction

To use JOID as a Consumer, there are basically two steps.

1. Add OpenIdFilter to your web.xml
2. Create an OpenID login form

OpenIdFilter

Add the following to web.xml

        <filter>
		<filter-name>OpenIdFilter</filter-name>
		<filter-class>org.verisign.joid.consumer.OpenIdFilter</filter-class>
		<init-param>
			<param-name>saveInCookie</param-name>
			<param-value>true</param-value>
			<description>Optional. Will store the identity url in a cookie under "openid.identity" if set to true.</description>
		</init-param>
		<!--
		<init-param>
			<param-name>cookieDomain</param-name>
			<param-value>www.mydomain.com</param-value>
			<description>Optional. Domain to store cookie based on RFC 2109. Defaults to current context.</description>
		</init-param>
		-->
	</filter>
        <filter-mapping>
		<filter-name>OpenIdFilter</filter-name>
		<url-pattern>/*</url-pattern>
	</filter-mapping>

OpenID Form

This form will accept a users OpenID URL identifier and upon submit, it redirects to the OpenID server identified by the URL and asks the user to accept the authentication request.
