it's happening when browser attempts fetch css, js or other static resources taoconnection-servlet.xml. same occurs on both jetty , tomcat7 deployments. after couple of hours searching can't find similar problem.

edit: i'm making call /account request mapping happens request mapping access static resources. if try access resources directly in browser e.g. http://localhost:8080/css/bootstrap.min.css or http://localhost:8080/js/sb-admin-2.js exception thrown.

alternatively if try access fake resource e.g. http://localhost:8080/js/fake.js still standard http 404 expected ioexception not thrown.
