Answer 1

I guess some library is missing because I download library à la carte

you download from here as a package instead of you download à la carte

setup GUIDELINE http://hibernate.org/validator/documentation/getting-started/

Import and include library below in your project

• classmate-1.1.0.jar
• javax.el-2.2.4.jar
• javax.el-api-2.2.4.jar
• jboss-logging-3.2.1.Final.jar
• validation-api-1.1.0.Final.jar
• hibernate-validator-5.2.2.Final.jar
• hibernate-validator-annotation-processor-5.2.2.Final.jar
• hibernate-validator-cdi-5.2.2.Final.jar

Then your code should be working.
