Ok.... I got it to work. Thank you

Once I added the certificate to the local JRE cacerts file, I could view the page.
The procedure to do this is outlined in the link below.

[edit] This resolves the problem but it got me thinking about what if you need to distribute the application? You can't expect the end-user to have to add the certificate manually. The certificate is a purchased, perfectly valid certificate (issued by DigiCert) and works in other browsers so it seems strange that this behavior is specific to browsers like curl and webview.
