I can't seem to get saml2 working. Here is what I have done.
I downloaded the sample application from here: https://github.com/spring-projects/spring-security-saml, this was a link from their documentation: http://docs.spring.io/spring-security-saml/docs/1.0.x/reference/html/chapter-quick-start.html
1) converted the sample application 'saml2-sample' into an eclispe project: mvn eclipse:eclipse
2) built the project: mvn package
3) added the 'Dynamic Web Module` facet to the project:
Right Click on project > Properties > Project Facets
4) Run the application on the STS Server:
Right Click on project > Run As > Run on Server
Server starts up and everything looks ok in the console except the url loads with HTTP Status 404 - /spring-security-saml2-sample/
at the URL http://localhost:8080/spring-security-saml2-sample/
