Spring 3 integration with Commons Validation framework

Hi ,


I am newbie to Spring framework. I have built a very small sample application to start with , using Spring 3 MVC module.
Application consists of single screen which asks for UserName and Password. On submit , I would be displaying values entered on next page. Now, I wanted to put validation in my application. I wanted to try both client and server side validations so I tried integrating commons validator framework with Spring 3 MVC. Following is what I did :

In my validation-servlet.xml , I wrote :

Code:

---

<bean id="validatorFactory" class="org.springmodules.validation.commons.DefaultValidatorFactory">
        <property name="validationConfigLocations">
              <list>
                <value>/WEB-INF/validation.xml</value>
                <value>/WEB-INF/validator-rules.xml</value>
              </list>
          </property>
 </bean> 
   
 <bean id="beanValidator" class="org.springmodules.validation.commons.DefaultBeanValidator">
          <property name="validatorFactory" ref="validatorFactory"/>
 </bean>

(to be continued .. 10000 characters exceeded :) )

Following is my validator-rules.xml ( which I copied from some post :) ) :

Code:

Following is my validation.xml :

Code:

---

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE form-validation PUBLIC
          "-//Apache Software Foundation//DTD Commons Validator Rules Configuration 1.1.3//EN"
          "http://jakarta.apache.org/commons/dtds/validator_1_1_3.dtd">
 
<form-validation>
      <formset>
            <form name="validationForm">
                <field property="uname" depends="required">
                </field>
            </form>
      </formset>
</form-validation>

---

following is my only Controller ( annotations are used ) :

Code:

---

@Controller("ValidationController")
public class ValidationController {

    @Autowired
    @Qualifier("beanValidator")
    private Validator beanValidator; 
       
        @RequestMapping(value="/validation.do",method=RequestMethod.GET)
        public String pre(ModelMap map){
               
                map.put("validationModel", new ValidationModel());
                return "validation";
        }
       
       
        @RequestMapping(value="/validationSubmit.do",method=RequestMethod.POST)
        public String post(@ModelAttribute ValidationModel model, BindingResult result){
               
                  beanValidator.validate(model, result);
                 
                if(result.hasErrors()) {         
                    return "validation";
                }
               
                return "validation";
        }
}

---

and following is form tag in validation.jsp :

Code:

---

<form:form id="validationForm" name="validationForm" commandName="validationForm"
                modelAttribute="validationModel" action="validationSubmit.do">
                <table>
                        <tr>
                                <td>User Name</td>
                                <td>
                                        <form:input path="uname"></form:input>
                                        <form:errors path="uname"/>                                                                      </td>
                        </tr>
                        <tr>
                                <td>Password</td>
                                <td>
                                        <form:input path="pwd"></form:input>
                                </td>
                        </tr>
                        <tr>
                                <td><input type="submit" value="Validate" />
                                </td>
                        </tr>
                </table>
        </form:form>

When I run this application , page with username and password textboxes appear. If I dont put any value in username and do submit, I am expecting that defined validation (Required) should run . but , "result.hasErrors()" in controller returns "false" ( meaning validation is not working) . Can any one pl help me out in this .

Any sort of example link/post/article would also be of great help. Thanks :)
