How To Configure /oauth/token ModelAndView in Spring - spring

Question

I successfully configured an oauth spring application. However, my headache is how to make it return to the login page with a successful token; The log shows the following entry:
`DEBUG o.s.web.servlet.DispatcherServlet - Null ModelAndView returned to DispatcherServlet with name 'dispatcher': assuming HandlerAdapter completed request handling`
Here is my login page:
` <c:url value="/oauth/token" var="loginProcessingUrl"/>
<form:form action="${loginProcessingUrl}" method="post">
<fieldset>
<legend>Please Login</legend>
<!-- use param.error assuming FormLoginConfigurer#failureUrl contains the query parameter error -->
<c:if test="${param.error != null}">
<div>
Failed to login.
<c:if test="${SPRING_SECURITY_LAST_EXCEPTION != null}">
Reason: <c:out value="${SPRING_SECURITY_LAST_EXCEPTION.message}" />
</c:if>
</div>
</c:if>
<!-- the configured LogoutConfigurer#logoutSuccessUrl is /login?logout and contains the query param logout -->
<c:if test="${param.logout != null}">
<div>
You have been logged out.
</div>
</c:if>
<c:if test="${param.success != null}">
<div>
You have been successfully been authenticated.
</div>
</c:if>
<p>
<label for="username">Username</label>
<input type="text" id="username" name="username"/>
</p>
<p>
<label for="password">Password</label>
<input type="password" id="password" name="password"/>
</p>
<!-- if using RememberMeConfigurer make sure remember-me matches RememberMeConfigurer#rememberMeParameter -->
<p>
<label for="remember-me">Remember Me?</label>
<input type="checkbox" id="remember-me" name="remember-me"/>
<input type="hidden" id="client_id" name="client_id" value="11111111"/>
<input type="hidden" id="client_secret" name="client_secret" value="2222222"/>
<input type="hidden" id="grant_type" name="grant_type" value="password"/>
<input type="hidden" id="response_type" name="response_type" value="token"/>
<input type="hidden" id="redirect_uri" name="redirect_uri" value="/login?success=1"/>
</p>
<div>
<button type="submit" class="btn">Log in</button>
</div>
</fieldset>
`
And here's my spring-security.xml file:
`<http pattern="/oauth/token" create-session="stateless" authentication-manager-ref="authenticationManager"
xmlns="http://www.springframework.org/schema/security">
<intercept-url pattern="/oauth/token" access="IS_AUTHENTICATED_FULLY" />
<anonymous enabled="false" />
<http-basic entry-point-ref="clientAuthenticationEntryPoint" />
<custom-filter ref="clientCredentialsTokenEndpointFilter" before="BASIC_AUTH_FILTER"/>
<access-denied-handler ref="oauthAccessDeniedHandler" />
</http>`
Why can't I go back to the login page once a token is successfully issued. Any help is appreciated.
Thanks
