JPA
Configured Hibernate 5.2 as JPA implementor in Apache Tomcat (TomEE)/8.5.11 (7.0.3) from this Article (TomEE 7 and Hibernate 5.2 persistence.xml)
Bean Validation
To implement Hibernate Validator as Bean Validator, placed hibernate-validator-5.4.0.Final.jar, hibernate-validator-annotation-processor-5.4.0.Final.jar, hibernate-validator-cdi-5.4.0.Final.jar in <TomEE-Home>/lib folder and removed bval-core-1.1.2.jar, bval-jsr-1.1.2.jar
But while deploying webapp gives following error:
DEBUG: No META-INF/validation.xml found. Using annotation based configuration only.

How to resolve this problem????
As specified in Hibernate Validator documentation (here), If application runs in an environment which does not provide CDI integration out of the box, you may use the Hibernate Validator CDI portable extension by adding the hibernate-validator-cdi
Apache Tomcat (TomEE)/8.5.11 (7.0.3) implements CDI with Apache OpenWebBeans out of the box.
Problem resolved after removing the hibernate-validator-cdi-5.4.0.Final.jar from <TomEE>/lib folder.
