Sorry, I got confused from yesterday and continued the question on my second machine without realizing .
I have two machines. The one I started the question with is: Machine number 1. Ubuntu 14.04, Tomcat7 as my web server, I have postgreSQl 9.3 installed as my dbServer. java version 1.8.9_91 Machine number 2 RHEL 6, Tomcat6 as web server, postgreSQL 9.3 dbServer. java version 1.7.0_101 I am focusing my effort on the first machine. (Ubuntu).. Andy.
