WSO2 Identity Solution has a in-build Java Relying Party Application that uses Information Card Login. It is a simple JSP site, where information card login is enabled using a servlet filter. This sample relying party accepts tokens issued by Sample Idp.
Start the Identity Solution application. Obtain a managed card from Sample Idp and point your browser to "https://localhost:12433/javarp". Clicking on the link "Login with your InfoCard" will give you pop up the Identity Selector.
Code for this sample is available in the source distribution under "modules/samples/servlet-filter"
