BindingResult is not showing any errors during form Validation

[Raihan Jamal]

I am using annotation based validation for one of my forms and I am not able to show any errors using the **form:errors tag** I used in JSP file. When I try to debug it, I found out that the BindingResult does not show any errors as well but I am leaving the textbox empty to test the validation. Any pointers are greatly appreciated why I am not able to validate it.

Below is my Controller Class

    @Controller
    public class RequestController {
    @RequestMapping(value = "/requestform", method = RequestMethod.GET)
    public ModelAndView request() {
	return new ModelAndView("requestform", "command", new RequestForm());
    }

    @RequestMapping(value = "/showResponse", method = RequestMethod.POST)
    public String showResponse(@ModelAttribute("berequest") @Valid RequestForm berequest, BindingResult errors,
	    ModelMap model) {

	if (errors.hasErrors()) {
	    return "requestform";
	} else {
		 StringBuilder url = "Some URL"

	    RestTemplate restTemplate = new RestTemplate();

	    String result = restTemplate.getForObject(url.toString(), String.class);

	    ObjectMapper mapper = new ObjectMapper();
		Object json = mapper.readValue(result, Object.class);
		String indented = mapper.defaultPrettyPrintingWriter().writeValueAsString(json);

		model.addAttribute("response", (indented));

	    return "resultform";
    	}
	}

Below is my model class-

	
	import javax.validation.constraints.NotNull;

	import org.hibernate.validator.constraints.NotBlank;
	import org.hibernate.validator.constraints.NotEmpty;

	public class RequestForm {

    @NotNull
    @NotBlank
    @NotEmpty
    private String userId;
	
    .....
	}

Below is my requestform.jsp file

		<fieldset>
			<legend>User Details:</legend>
				<form:label path="userId" for="input-one" class="float"><strong>User Id:</strong></form:label><br />
				<form:input path="userId" class="inp-text" name="input-one-name" id="input-one" type="text" size="100" />
				<form:errors path="userId" cssClass="error"/><br />
				
		</fieldset>
		

Below is my context.xml file

    	<!-- DispatcherServlet Context: defines this servlet's request-processing infrastructure -->
    	
    	<!--  Allow proxys -->
    	<aop:aspectj-autoproxy />
    	
    	<!-- Enables the Spring MVC @Controller programming model -->
    	<mvc:annotation-driven>
    			<mvc:message-converters>
    			  <!--  Support AJAX processing with progressive rendering. Overrides HttpOutputMessage with RaptorResponseWriter -->
    			<beans:bean class="com.host.kernel.filter.RaptorJacksonHttpMessageConverter"/>					
    			</mvc:message-converters>
    		
    	<!-- support JSR303 annotation if JSR 303 validation present on classpath -->
    	<mvc:annotation-driven />
    	
    	<context:component-scan base-package="com.host.config" />
    	<context:component-scan base-package="com.host.app.raptor.controller" />	 	
    
    	<!-- Handles HTTP GET requests by efficiently serving up static resources 
    	     in the corresponding directory -->
    	<resources mapping="/js/**" location="/js/" />
    	<resources mapping="/css/**" location="/css/" />
     
    	<!-- Resolves views selected for rendering by @Controllers to .jsp resources in the /WEB-INF/views directory -->
    	<beans:bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
    		<beans:property name="prefix" value="/WEB-INF/views/" />
    		<beans:property name="suffix" value=".jsp" />
    	</beans:bean>
    </beans:beans>

Can anyone tell me what wrong I am doing here?

At first glance your names do not look consistent. You are naming your model command when you render the view but when you show the response you are calling it berequest.
