Tomcat - CertificateFile must be defined when using SSL with APR error

Setting Tomcat to use SSL and I was getting the "Connector attribute SSLCertificateFile must be defined when using SSL with APR" error. Had to disable APR in server.xml as follows:

  <!--
  <Listener className="org.apache.catalina.core.AprLifecycleListener" SSLEngine="on" />
  -->
