here when login fails need retain username.i tried

<form:form> <form:input path="username" /> </form:form> 

but dont know use above code, please me on this.

we have tag in our login.jsp, seems work ok:

<input id="j_username"        type="text"        name="j_username"        value="${sessionscope.spring_security_last_username}"        placeholder="username"        class="form-control no-border"> 

the $sessionscope.spring_security_last_username seems trick.
