I have a website that uses a JPA connection pool.
Now I want to configure HikariCP and use its pool with my application.
This is my persistence.xml:

<?xml version="1.0" encoding="UTF-8"?>

      <property name="eclipselink.cache.shared.default" value="false"/>
      <property name="eclipselink.logging.level" value="OFF"/>

      <!-- eclipse pool -->

      <property name="eclipselink.connection-pool.default.min" value="8" />
      <property name="eclipselink.connection-pool.default.max" value="13" />
      
   

   
    </properties>
  </persistence-unit>
</persistence>

I’ve searched, but I didn’t find any useful articles.
