I'm looking for a tool to define and execute object mapping in java.
Most of the tools I found like
Defines mapping on java classes and properties.
Now I will be facing multitude of formats and sources of data, some without explicit schema, some with, some having defined schema but not conforming to it. I feel that defining java model for each of them is not work the effort so I'm looking for tool that allows me to define mapping and work on javax.json.JsonObject (or some other json representation).
It would be best if it allows to externalize mapping, but java DSL is also acceptable.
