Unable to find valid certification path to requested target

I have a class that will download a file from a https server. When I run it, it returns a lot of errors. It seems that I have a problem with my certificate. Is it possible to ignore the client-server authentication? If so, how?

The problem appears when your server has self signed certificate. To workaround it you can add this certificate to the list of trusted certificates of your JVM.

You can either edit JAVA_HOME/jre/lib/security/cacerts file or run you application with -Djavax.net.ssl.trustStore parameter. Verify which JDK/JRE you are using too as this is often a source of confusion.
