I spend hours trying to figure this out and here are the fruits of my labor

Problem

You are unable to create a valid Tomcat Keystore using a GoDaddy crt and key file

Curl output may look like this:

curl: (60) SSL certificate problem, verify that the CA cert is OK. Details:
error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed

Getting the Script

curl -O https://raw.github.com/ssstonebraker/braker-scripts/master/working-scripts/crt_to_keystore.sh
chmod +x crt_to_keystore.sh

Using the script

./crt_to_keystore.sh <path_to_crt> <path_to_key>

It sounds like you may want to try to edit the server.xml for your Tomcat application, and where the Connector port is defined, add something like:

proxyName="mysite.example.com" proxyPort="443" scheme="https" secure="true"
