How to import SSL certificates into JVM trust store?

I was trying to set up OpenSSO Distributed Authentication UI (DAUI) server on Sun Web Server 7 (aka Oracle iPlanet Server) to communicate with my backend OpenSSO Enterprise Server. The OpenSSO Enterprise Server is SSL-enabled for security reason.

In our development environment, we install self-signed certificate onto the Glassfish Application Server that hosts the OpenSSO Enterprise Server.

In order for DAUI to communicate securely with the OpenSSO Enterprise Server, we need to import the self-signed CA certificate into the Sun Web Server JVM.

The task can be daunting for people who do not play with SSL day-in-day-out.

Luckily, I found a very useful blog. Amazing! Wrote in 2006, still works like a charm in 2010!

Thank you, Andreas!
