JBoss Portal identity application is using MyFaces MyFaces jar libraries are in portal-identity.sar\portal-identity.war\WEB-INF\lib2 (sic!) folder this is where portal-core-identity-ui-lib.jar files is which contains build in CaptachValidator class. I placed my jar file into jboss-portal.sar\portal-identity.sar\lib\ which makes it available to the whole identity application. So does the anwser mean I need to put my jar file (which contains just validator class) into portal-identity.sar\portal-identity.war\WEB-INF\lib2?
