Install a certificate in Oracle Weblogic 8-11

If you are using Weblogic 8 with a java keystore, install the certificate in the keystore the same way you'll do it under Tomcat, Install a Tomcat certificate.

If you are using seperate files, concatenate the server certificate and the certification chain into one file in that precise order.
