When i try to log in to Identity Server via the webapp, after entering the credentials and trying to sign in it throws the following error. java.lang.NullPointerException org.wso2.identity.saml2.demo.SamlConsumerManager.getResult(SamlConsumerManager.java:278) org.wso2.identity.saml2.demo.SamlConsumerManager.processResponseMessage(SamlConsumerManager.java:252) org.wso2.identity.saml2.demo.SAML2ConsumerServlet.doPost(SAML2ConsumerServlet.java:77) javax.servlet.http.HttpServlet.service(HttpServlet.java:647) javax.servlet.http.HttpServlet.service(HttpServlet.java:728) *note* *The full stack trace of the root cause is available in the Apache Tomcat/7.0.39 logs.* I debugged the source and this is given as the reason for the exception. [Fatal Error] :1:1: Content is not allowed in prolog. org.xml.sax.SAXParseException: Content is not allowed in prolog. at org.apache.xerces.parsers.DOMParser.parse(Unknown Source) at org.apache.xerces.jaxp.DocumentBuilderImpl.parse(Unknown Source) at javax.xml.parsers.DocumentBuilder.parse(DocumentBuilder.java:124) at org.wso2.identity.saml2.demo.SamlConsumerManager.unmarshall(SamlConsumerManager.java:265) at org.wso2.identity.saml2.demo.SamlConsumerManager.processResponseMessage(SamlConsumerManager.java:238) at org.wso2.identity.saml2.demo.SAML2ConsumerServlet.doPost(SAML2ConsumerServlet.java:77) at javax.servlet.http.HttpServlet.service(HttpServlet.java:647) at javax.servlet.http.HttpServlet.service(HttpServlet.java:728) at The webapp works fine as expected with the IS 3.2.3 version. May be this is due to some changes made in the 4.1.0 version. Thanks!
