Loading and applying model in version 6.5 and 7.1

Hi,

I am wondering if newer versions of RM supports reading and applying a trained model from java applications?

After a fake model was trained I tried to use it in the following scenarios:
a) Build a process in RapidMIner 7 GUI  and run the process from java app. Result was an error about a non existing legacy:read_model operator. When I checked in operator.xml it was not there so probably in this version it was removed.
b) Tried the above step in RapidMiner 6.5
c)  Implemented a new process in the app but did not know how to load the model. In previous versions there was a ModelLoader.class which seems now to be depracated?

Any help appreciated!

Thank you
