If I need to deploy an enterprise Java application to the OpenShift Flex cloud, which one of the following options is the correct (or appropriate / best) approach:
Use the OpenShift Eclipse Plug-In for Java applications - as mentioned in the link
Use the Boxgrinder tool to create appliance (of the enterprise Java app) and then create the instance of the generated appliance in the Openshift cloud.
I don't think OpenShift presently lets you use your own images/instances? I'll ask around and see what the OS guys say.
