This is a simple Red Hat OpenShift example containing a JavaEE6 servlet that illustrates some of the steps in the MongoDB Java Tutorial: http://www.mongodb.org/display/DOCS/Java+Tutorial
Create an account at http://openshift.redhat.com/
Create a jbossas-7 application (you can call your application whatever you want)
rhc app create -a testmongo -t jbossas-7
Add MongoDB to your application
rhc app cartridge add -a testmongo -c mongodb-2.0
Add this upstream repo
cd testmongo
git remote add upstream -m master git://github.com/openshift/jbossas-mongoDB-quickstart.git
git pull -s recursive -X theirs upstream master
Then push the repo upstream
git push
