We've been trying to test SAML ECP with the last 2 Keycloak releases and we are getting a server 500 error caused by a NoClassDefFoundError for javax/xml/soap/MessageFactory. The odd thing is that the class is in one of the jars: % jar -tf modules/system/layers/base/javax/xml/soap/api/main/jboss-saaj-api_1.3_spec-1.0.3.Final.jar lists javax/xml/soap/MessageFactory.class Can someone explain what is going on or how to fix it? Attached (so the mailer does not mangle it) is the exception in the server.log file -- John _______________________________________________ keycloak-dev mailing list keycloak-dev(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/keycloak-dev
