Patientview runs on tomcat and is written in java. Currently it uses java 7 and runs on tomcat 7. Plans are in place to upgrade to java8 and tomcat 8.5 which will require running tomcat from source.
RedHat 6 doesn't support tomcat 7 so the servers have run using the EPEL release however when an issue occurred with the latest release version we were forced to run a source code version temporarily until the fixed version of tomcat came out. The server is split between two instances of tomcat. One run from source located in /opt/tomcat-importer (tomcat 7.0.52) which runs the importer tasks and handles the rabbitmq queue of messages and the other which runs the main site and api. There is an nginx front end that routes traffic to the correct local ports.
