Problems with Hibernate Validator

[Jordi Rubio]

Hi,

I'm trying to validate a form using Spring WebFlow and Hibernate Validator Annotations, but I'm doing something wrong.

If I use the Spring validation way (ValidationContext, MessageContext, validate${state}, etc), all works fine, but I want to use the Hibernate Annotations like @Email, @NotEmpty, etc.

I've read a lot of forums, Spring documentation, but I don't know what I'm doing wrong.

At this moment, this is my view-state and next action code:

	<var name="user" class="myproject.web.pojo.User"/>

  	<view-state id="startSignup" model="user">
	    <binder>
	        <binding property="email" />
	        <binding property="name" />
	        <binding property="lastName" />
	        <binding property="password" />
	    </binder>
 		<on-entry>
 			<set name="flowScope.user" value="new info.teaming.web.pojo.User()" />
 		</on-entry>
 		<transition on="dataEntered" to="lookupUser" />
	</view-state>

	<action-state id="lookupUser">
		<evaluate expression="signupActions.lookupUser(user)" />
		<transition to="startSignup"
on-exception="myproject.web.service.exception.UserAlreadyExistsException" />
		<transition to="saveOrder" />
	</action-state>
        (...)

This is the startSignup.jsp code:

<!--  sf:form method="POST" modelAttribute="user" -->
<sf:form method="POST" commandName="user" >
	<input type="hidden" name="_flowExecutionKey" value="${flowExecutionKey}" />
	<fieldset>
		<table cellspacing="0">
			<tr>
				<th>
					<label for="name"><fmt:message key="signUp.name"/></label>
				</th>
				<td>
					<sf:input path="name" size="25" id="name" />
				</td>
				<sf:errors path="name" />
			</tr>
			<tr>
				<th>
					<label for="lastName"><fmt:message key="signUp.lastName"/></label>
				</th>
				<td>
					<sf:input path="lastName" size="45" maxlength="45" id="lastName" />
				</td>
			</tr>
			<tr>
				<th>
					<label for="password"><fmt:message key="signUp.password"/></label>
				</th>
				<td>
					<sf:password path="password" size="20" showPassword="true" id="password" />
				</td>
			</tr>
			<tr>
				<th>
					<label for="email"><fmt:message key="signUp.email"/></label>
				</th>
				<td>
					<sf:input path="email" size="30" id="email" />
				</td>
			</tr>
			<tr>
				<td>
					<input type="submit" name="_eventId_dataEntered" value="<fmt:message key="signUp.register"/>"/>
				</td>
			</tr>
		</table>
	</fieldset>
</sf:form>

This is the myproject.web.pojo.User POJO code:

import java.io.Serializable;

import org.hibernate.validator.constraints.Email;
import org.hibernate.validator.constraints.Length;
import org.hibernate.validator.constraints.NotEmpty;

public class User implements Serializable {

	private static final long serialVersionUID = 1L;

	@NotEmpty
    @Length(min = 2, max = 25)  
    private String name;  
      
    @NotEmpty
    @Email
    private String email;  
      
    @NotEmpty
    @Length(min = 2, max = 45)  
    private String lastName;  

    @NotEmpty
    @Length(min = 6, max = 20)
    private String password;
    
    public String getName() {  
        return name;  
    }  
  
    public void setName(String name) {  
        this.name = name;  
    }  
      
    public String getEmail() {  
        return email;  
    }  
  
    public void setEmail(String email) {  
        this.email = email;  
    }  
  
	public void setPassword(String password) {
		this.password = password;
	}

	public String getPassword() {
		return password;
	}

	public void setLastName(String lastName) {
		this.lastName = lastName;
	}

	public String getLastName() {
		return lastName;
	}  
	
//	public void validateStartSignup(ValidationContext context) {
//		MessageContext messages = context.getMessageContext();
//		
//		messages.addMessage(new MessageBuilder().error().source("name").code("user.name.notEmpty").build());
//	}
	
}

(note: as you can see, when I work with Spring Validation, the form validates successfully)

And finally, this is my SignupAction code:

import myproject.web.model.UsrUser;
import myproject.web.model.dao.UsrUserDAO;
import myproject.web.pojo.User;
import myproject.web.service.exception.UserAlreadyExistsException;

import javax.annotation.Resource;
import javax.validation.Valid;

import org.springframework.stereotype.Component;
import org.springframework.webflow.action.MultiAction;
import org.springframework.webflow.execution.Event;

@Component
public class SignupActions extends MultiAction {

	@Resource
	UsrUserDAO usrUserDAO;
	
	private static final long serialVersionUID = 1L;
	
	public Event lookupUser(@Valid User user) throws UserAlreadyExistsException {
		try {
			usrUserDAO.findByEmail(user.getEmail());
		} catch (javax.persistence.NoResultException e) {
			return success();
		}
		
		throw new UserAlreadyExistsException();
	}

	public void saveUser(UsrUser user) {
		return;
	}

}

When I work with Hibernate Validation, the flow arrives to the saveUser method, without any validation.

What I'm doing wrong?

Thanks a lot for helping me!

Oh! I forgot to tell you that I'm using Spring 3!!!

Spring 3.0.5.RELEASE
Spring WebFlow 2.2.1.RELEASE
Hibernate Validator 4.0.2.GA

Sorry about that!

Hi,

I am using an iMac and Windows XP on Boot Camp/parallels. I have been using Firefox for Connect meeting on both systems for several months and have not experienced problems. I dont however, have a lot of people attending meetings - rarely more than 4 at a time. I doubt that Firefox is your problem.

I did have some web site issues when using Safari - not with Connect however. It too seemed to function smoothly for Connect participation. I have the plug-in installed for both systems.
