Re: [keycloak-user] Error while loading the application

Hi All, We are using Keycloak SAML adapters to authenticate our applications with Keyclaok. The setup was working fine and the applications were able to authenticate the users. However since today we are getting the below error while loading the application and this is resulting in a black page for the client. Can you please check in case anyone has seen this issue before. Is this related to java versions as I have not changed anything in the environments recently. 2016-12-09 08:08:08,875 [ajp-/10.7.24.224:8009-2] ERROR [org.apache.catalina.connector] JBWEB001018: An exception or error occurred in the container during the request processing: java.lang.AbstractMethodError: javax.xml.transform.TransformerFactory.setFeature(Ljava/lang/String;Z)V at __redirected.__TransformerFactory.setFeature(__TransformerFactory.java:161) at org.keycloak.saml.common.util.TransformerUtil.getTransformerFactory(TransformerUtil.java:113) at org.keycloak.saml.common.util.TransformerUtil.getTransformer(TransformerUtil.java:81) at org.keycloak.saml.common.util.DocumentUtil.getDocumentAsString(DocumentUtil.java:238) at org.keycloak.saml.common.util.DocumentUtil.asString(DocumentUtil.java:454) at org.keycloak.saml.processing.core.util.XMLSignatureUtil.sign(XMLSignatureUtil.java:340) at org.keycloak.saml.processing.api.saml.v2.sig.SAML2Signature.sign(SAML2Signature.java:143) at org.keycloak.saml.processing.api.saml.v2.sig.SAML2Signature.signSAMLDocument(SAML2Signature.java:160) at org.keycloak.saml.BaseSAML2BindingBuilder.signDocument(BaseSAML2BindingBuilder.java:266) at org.keycloak.saml.BaseSAML2BindingBuilder$BasePostBindingBuilder.<init>(BaseSAML2BindingBuilder.java:145) at org.keycloak.saml.BaseSAML2BindingBuilder.postBinding(BaseSAML2BindingBuilder.java:208) at org.keycloak.adapters.saml.SamlUtil.sendSaml(SamlUtil.java:38) at org.keycloak.adapters.saml.profile.AbstractSamlAuthenticationHandler$5.sendAuthnRequest(AbstractSamlAuthenticationHandler.java:463) at org.keycloak.adapters.saml.AbstractInitiateLogin.challenge(AbstractInitiateLogin.java:60) at org.keycloak.adapters.saml.AbstractSamlAuthenticatorValve.executeAuthenticator(AbstractSamlAuthenticatorValve.java:247) at org.keycloak.adapters.saml.AbstractSamlAuthenticatorValve.authenticateInternal(AbstractSamlAuthenticatorValve.java:222) at org.keycloak.adapters.saml.jbossweb.SamlAuthenticatorValve.authenticate(SamlAuthenticatorValve.java:41) at org.apache.catalina.authenticator.AuthenticatorBase.invoke(AuthenticatorBase.java:465) at org.keycloak.adapters.saml.AbstractSamlAuthenticatorValve.invoke(AbstractSamlAuthenticatorValve.java:184) at org.jboss.as.web.security.SecurityContextAssociationValve.invoke(SecurityContextAssociationValve.java:169) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:145) at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:97) at org.jboss.as.web.sso.ClusteredSingleSignOn.invoke(ClusteredSingleSignOn.java:384) at org.apache.catalina.valves.AccessLogValve.invoke(AccessLogValve.java:559) at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:102) at com.redhat.container.UTF8Valve.invoke(UTF8Valve.java:26) at com.redhat.container.redirect.RedirectToInternalValve.invoke(RedirectToInternalValve.java:61) at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:336) at org.apache.coyote.ajp.AjpProcessor.process(AjpProcessor.java:490) at org.apache.coyote.ajp.AjpProtocol$AjpConnectionHandler.process(AjpProtocol.java:420) at org.apache.tomcat.util.net.JIoEndpoint$Worker.run(JIoEndpoint.java:926) at java.lang.Thread.run(Thread.java:745) -- Thanks, Pulkit AMS _______________________________________________ keycloak-user mailing list keycloak-user(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/keycloak-user
