Vaadin 7 - Bean Validation

Question

I have been trying out Vaadin 7. Firstly, I must admin that I am quiet a noob at Vaadin and not much familiar with JAVA persistance. I am thus trying to learn bean validation and how to use it. I have followed couple of tutorials, but its really hard to decide which is the latest and correct one for Vaadin 7. Nonetheless, I tried downloading and using the JPA container and the BeanValidator and I can't get it working. Here is the code I am using:

package com.example.firstvaadin;

import java.io.Serializable;

import org.hibernate.validator.constraints.Email;
import javax.validation.constraints.*;

public class RegisterBean implements Serializable{

    public  RegisterBean(String email){
        this.email = email;
    }

    @Size(min = 5, max = 50)
    private String email;

    public void setEmail(String email) {
        this.email = email;
    }

    public String getEmail() {
        return email;
    }
}

and

RegisterBean rbean = new RegisterBean("");
BeanItem<RegisterBean> item = new BeanItem<RegisterBean>(rbean);
TextField email = new TextField("email",item.getItemProperty("email"));
email.setImmediate(true);
layout.addComponent(email);
email.setNullRepresentation("");

but I hit run-time exceptions on the following Code: email.addValidator(new BeanValidator(RegisterBean.class, "email"));

The exception is:
    aused by: com.vaadin.event.ListenerMethod$MethodException: Invocation of method buttonClick in com.example.firstvaadin.LoginView$1 failed.

I have no idea which classes are missing and I have added hibernate jars and validation-api.jar

Can someone please give me a hand?

Also, here is a list of jar files that are in the /WebContent/WEB-INF/lib directory and added as classpath in Eclipse.

classmate-0.8.0.jar
hibernate-jpa-2.0-api-1.0.1.Final.jar
hibernate-search-engine-4.3.0.Alpha1.jar
hibernate-search-orm-4.3.0.Alpha1.jar
hibernate-validator-5.0.0.Final.jar
hibernate-validator-annotation-processor-5.0.0.Final.jar
hibernate-validator-cdi-5.0.0.Final.jar
javax.el-2.2.4.jar
javax.el-api-2.2.4.jar
jboss-logging-3.1.1.GA.jar

mysql-connector-java-5.1.22-bin.jar
vaadin-sqlcontainer-1.1.0.jar
validation-api-1.0.0.GA.jar
validation-api-1.1.0.Final.jar

The classnotfound exception is gone but have a new one now:

I'm sure you've already resolved your issue, but for others coming to this late (as I am) and also using Vaadin 7 Framework, the Vaadin Bean Validator is not compatible with Vaadin 7, only Vaadin 6 as mentioned on their download page here:

https://vaadin.com/directory#addon/vaadin-bean-validation

Even in their own demo (jpacontainer-addressbook-demo) they use the hibernate-validator in the pom.xml:

    <dependency>
        <groupId>org.hibernate</groupId>
        <artifactId>hibernate-validator</artifactId>
        <version>4.2.0.Final</version>
    </dependency>

Hope this helps out others as it has me.

Vaadin 7 does not need an add-on for that. – Bruno Medeiros Aug 25 '16 at 19:25 — Bruno Medeiros, Aug 25 '16 at 19:25

you don't need hibernate-validator-annotation-processor-5.0.0.Final.jar as a runtime dependency. This is a development library helping to avoid wrong placements of constraints during development.

Regarding validation-api, removing validation-api-1.0.0.GA.jar works, because you are adding two different version of the same library. validation-api-1.0.0.GA.jar is the API version for Bean Validation 1.0. This is compatible with Hibernate Validator 4.3.

validation-api-1.1.0.Final.jar is the Bean Validation 1.1 API which aligns with Hibernate Validator 5.x. Since you use the latter you need the Bean Validation 1.1 API. As simple as that.

You need to put some more dependencies in your project. I solved with this ones:

    <!--- Dependencies for validating Beans in Vaadin -->
    <dependency>
        <groupId>javax.validation</groupId>
        <artifactId>validation-api</artifactId>
        <version>1.1.0.Final</version>
    </dependency>
    <dependency>
        <groupId>org.jboss.logging</groupId>
        <artifactId>jboss-logging</artifactId>
        <version>3.2.1.Final</version>
    </dependency>
    <dependency>
        <groupId>org.slf4j</groupId>
        <artifactId>slf4j-log4j12</artifactId>
        <version>1.7.10</version>
    </dependency>
    <dependency>
        <groupId>org.slf4j</groupId>
        <artifactId>slf4j-simple</artifactId>
        <version>1.7.10</version>
    </dependency>
    <dependency>
        <groupId>org.hibernate</groupId>
        <artifactId>hibernate-validator</artifactId>
        <version>5.1.3.Final</version>
    </dependency>

With this its more than enought! You may specify the messages putting the message field in the javax.validation.constraints notation or putting internationalized ones in project properties, looking at the message default value like javax.validation.constraints.Size.message.

I believe you need to add the validation-api-1.0.0.GA.jar to WEB-INF/lib

I don't know if there are any any other dependencies.

Its already in the folder. I don't know what the problem could be? – Thinker Apr 23 '13 at 08:32
The class not found error is gone. It was as problem with adding the jars to the classpath. Now there is a new error which is addedd to the question. – Thinker Apr 23 '13 at 09:07
It appears that removing the `validation-api-1.0.0.GA.jar` and leaving the `validation-api-1.1.0.Final.jar` solves the problem. Can anyone shed some light? – Thinker Apr 23 '13 at 09:34
Well, going by the name of the jars - validation-api-1.1.0-Final supercedes validation-api-1.0.0.GA; you should use either one or the other, but not both. – Charles Anthony Apr 23 '13 at 09:38
