title: What are the relationships between JTA provider like Atomikos and connection pool like HikariCP?
body: <p>I'm reading <em>Java Persistence with Hibernate</em>, and I found the following text.</p>
  
  <blockquote>
    <p>Today, high-quality standalone JTA providers such as Bitronix (used for the example code of this book) and Atomikos are available and easy to install in any Java environment. Think of these solutions as <strong>JTA-enabled database connection pools</strong>.</p>
  </blockquote>
  
  <p>As I understand, JTA providers have their own connection pools.</p>
  
  <p>So, do they integrate (how, if they do) with connection pools like HikariCP and C3P0? Thank you. </p>
