I have a custom java action that calls an external business rules management system (BRMS). The BRMS expects to be passed java objects (pojo). The Mendix domain elements were built to match the java classes used by the BRMS. How would I map Mendix domain elements to the java class/objects expected by the BRMS? And will they get mapped back to the domain elements?
Use the generated proxies (as mentioned in your other question) or use the IMendixObject for interacting with all object types generically (see http://apidocs.mendix.com/)
