Hi jmraimundo,
You will see the following section in the server.xml:
<!-- Define a SSL HTTP/1.1 Connector on port 8443
This connector uses the JSSE configuration, when using APR, the
connector should be using the OpenSSL style configuration
described in the APR documentation -->
<!--
<Connector port="8443" protocol="HTTP/1.1" SSLEnabled="true"
maxThreads="150" scheme="https" secure="true"
clientAuth="false" sslProtocol="TLS" />
-->
As you can see - this section has the "<!--" flag and the "-->" flag at the start and end - meaning this SSL connector is commented out. You should also see another connector for non-ssl.
What you would do is uncomment the SSL connector, and then comment out the non-SSL connector.
This would force the SSL connector to be the only one available.
