Apache Tomcat 8 adds support for lots of Java EE 7 features like WebSockets, Servlet 3.1, JSP 2.3, Expression Language 3.0, as well as additional Tomcat-specific features. There is not much documentation around all that will be added in Apache Tomcat 8 but I found these presentation slides useful. Samples running Apache Tomcat 8 on OpenShift can be found at http://tomcat8-cix.rhcloud.com/ and http://tomcat8-cix.rhcloud.com/examples
- First create an OpenShift DIY application with your desired appname (here, using "tomcat8"):
rhc app create tomcat8 diy
- Add git remote to Tomcat 8 OpenShift quickstart and pull code from it.
cd tomcat8
git remote add upstream https://github.com/shekhargulati/openshift-tomcat8-quickstart.git
git pull -s recursive -X theirs upstream master
If you get an error saying fatal: refusing to merge unrelated histories use
git pull -s recursive -X theirs upstream master --allow-unrelated-histories
- Push the code to OpenShift.
git push
-
Check that Apache Tomcat 8 is up and running by going to http://tomcat8-{domain}.rhcloud.com. Replace {domain} with your own domain name.

Tomcat's examples will also be deployed. You can view them under http://tomcat8-{domain}.rhcloud.com/examples.
