Bean Validation @NotNull, @NotBlank and @NotEmpty does not work in JSF+Tomcat

Question

I am using Hibernate Validation annotations in my JSF managed bean. When I use @NotNull, @NotBlank or @NotEmpty they doesn't seem to be triggered in any way.

@NotBlank(message = "{name.required}")
public String name;

View:

<h:outputLabel value="Name:" /> 
<h:inputText id="name" value="#{person.name}" size="20" />
<h:message for="name" style="color:red" />

How is this caused and how can I solve it?

Answer 1

I had a similar issue and i was able to overcome the problem by including the below three jars in web-inf lib. Just add the hibernate validator jar and the required jars as provided in the zip file:

• hibernate-validator-4.3.0.Final.jar
• jboss-logging-3.1.0.CR2.jar
• validation-api-1.0.0.GA.jar

Answer 2

add

<context-param>
        <param-name>javax.faces.INTERPRET_EMPTY_STRING_SUBMITTED_VALUES_AS_NULL</param-name>
        <param-value>true</param-value>
    </context-param>

in web.xml

and add

<dependency>
            <groupId>javax.validation</groupId>
            <artifactId>validation-api</artifactId>
            <version>2.0.1.Final</version>
        </dependency>

        <dependency>
            <groupId>org.hibernate.validator</groupId>
            <artifactId>hibernate-validator</artifactId>
            <version>6.0.23.Final</version>
        </dependency>
    

    <dependency>
                <groupId>com.sun.faces</groupId>
                <artifactId>jsf-api</artifactId>
                <version>2.2.13</version>
            </dependency>
    
    
            <dependency>
                <groupId>com.sun.faces</groupId>
