1. A system for generating a target meta model file that can convert non-EMF (Eclipse Modeling Framework) objects to EMF-based objects in an EMF-based runtime environment, comprising: a system for inputting a source meta model that describes a data model and runtime support for the data model; a system for inputting an EMap file that maps non-EMF java classes to the source meta model; and an association mechanism that utilizes the Emap file to associate eClassifiers in the source meta model to non-EMF Java classes in the source meta model.
