Add this last step in configurations of PicketLink applications: The web application also requires a dependency defining in META-INF/MANIFEST.MF or jboss-deployment-structure.xml, so that the PicketLink classes can be located. Example: Define Dependency in META-INF/MANIFEST.MF Manifest-Version: 1.0 Build-Jdk: 1.6.0_24 Dependencies: org.picketlink Example: Define Dependency in META-INF/jboss-deployment-structure.xml <jboss-deployment-structure> <deployment> <dependencies> <module name="org.picketlink" /> </dependencies> </deployment> </jboss-deployment-structure>
This last step should be also added to 5.6.3. Configure Identity Provider as suggested in comment #1.
