SOA Suite 12c provides the option to use the Integrated WebLogicServer in JDeveloper as the development run time environment. It comes prepackaged, installs very easily and gets a developer up and running in less than 20-30 minutes. As part of this light(er) weight SOA Suite run time, there is an MDS Repository (file based). Deployment to this run time MDS is done in the usual way. The contents of this MDS instance can be inspected in JDeveloper and resources can be transferred to the local design time MDS instance or exported to a JAR file for further distribution. All you have to do is create a connection to this run time MDS instance.
