try following approach see whether still facing error
my assumption: you're displaying actual jsp on browser html extension.
modify studentregistration.java controller slightly, .e.g.
@controller public class studentregistration { @requestmapping(value = "/studentregistration", method = requestmethod.get) public string viewregistration(map<string, object> model) { student registerform = new student(); model.put("studentregistration", registerform); list<string> courselist = new arraylist<string>(); courselist.add("developer"); courselist.add("designer"); courselist.add("it manager"); model.put("courselist", courselist); return "studentregistration"; } @requestmapping((value = "/index", method = requestmethod.post) public string processregistration(@valid student registerform, map<string, object> model, bindingresult result) { if (result.haserrors()) { return "error"; } else { //do student registeration process ... return "index"; } }}- modify jsp on form tag
<form:form action="index.html" method="post" commandname="studentregistration" class="form-horizontal">
