Hi everybody, I am trying to create a Java text-based web browser in order to access a specific Apache web server. However, I am having the folowing error: ......................................................................................................................

I have tried adding the certificate of the website into Java's /jre/lib/security/cacerts directory; yet it would still not work. Is there anyway that I could bypass this certificate checking process from the client side? I understand that this post would be close to being off topic since it is mostly java-related, but any thoughts would be much appreciated.
