The exception :

Caused by: org.hibernate.exception.GenericJDBCException: Unable to acquire JDBC Connection
    at org.hibernate.exception.internal.StandardSQLExceptionConverter.convert(StandardSQLExceptionConverter.java:47)
Caused by: java.sql.SQLException: Cannot create JDBC driver of class 'oracle.jdbc.OracleDriver' for connect URL 'jdbc:oracle:[email protected]:1521:DATABASE'

Caused by: java.sql.SQLException: No suitable driver
    at org.apache.commons.dbcp2.BasicDataSource.createConnectionFactory(BasicDataSource.java:2152)

I tried to put the driver jar on lib folder of tomcat but same error

I'm getting the error also on Wildfly 10.1.

I see you are referring to wrong Package inside Oracle 7 jar. Use OracleDriver class name as follows oracle.jdbc.driver.OracleDriver

<property name="driverClassName" value="oracle.jdbc.driver.OracleDriver" />

You can always open the jar and locate the class for OracleDriver:

Please refer to this image to see the OracleDriver class path
