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:

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

validation-api-1.1.0.Final.jar
The classnotfound exception is gone but have a new one now:

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.
