title: Azure Glassfish Connection Pooling Communications Link Failure
body: <p>I have just set up a new Azure MySQL.
  I can connect to it via Workbench but not via Glassfish 4.1.2 connection pool.
  I am testing 2 installations of Glassfish. One on my machine (without SSL) another installation on another Azure VM (with SSL). But I get Communications Link Failure with every ping on both installations. While I can ping successfully via both installations to other MySQL on other machines.</p>
  <ul>
  <li>I get my connection string from Azure portal.</li>
  <li>All other GF connection pool configs are by default.</li>
  <li>I have SSL certificate installed on Azure VM Glassfish.</li>
  <li>I have allowed both ip addresses on azure portal (successful workbench connection).</li>
  </ul>
  <p>Is there any documentation or tutorial on Azure MySQL + Glassfish Connection Pooling config?
  I can't seem to find it. Or does anyone know what I'm missing? Please. Thank you.</p>
