How to generate self-signed cert for use with Tomcat7

Goal: To use a self-signed cert with my dev Tomcat server.

Step 1: Create a certificate with openssl following this Ubuntu certificate guide:

openssl req -new -key server.key -out server.csr

I followed the self-signed NO password guidance.

Step 2: Update Tomcat config file /etc/tomcat7/server.xml

 <Connector port="8443" protocol="HTTP/1.1" SSLEnabled="true"
            keystoreFile="/etc/ssl/private/server.key" keystorePass=""
            maxThreads="150" scheme="https" secure="true"
            protocol="org.apache.coyote.http11.Http11AprProtocol"
            clientAuth="false" sslProtocol="TLS"/>

Step 3: Restart Tomcat:

sudo service tomcat7 stop
sudo service tomcat7 start

Test through Chrome browser on another computer:

All SSL connections to server are refused, but standard http connections work. Error details in Chrome:

Google Chrome's connection attempt to [domain] was rejected. The website may be down, or your network may not be properly configured.

I have seen a plethora of instructions on how to get this to work. But I am confused at the dizzying array of methods. Not the least is some mention a keystore where others only mention cert files. Obviously my ignorance of the topic is in play here. Furthermore, I have a cert but according to many guides, I cannot import my key into a keystore as there is no facility for that.

Both ports 443 and 8443 are open on the server.

Any guidance is appreciated!
