How come service client set the env of the factory? It does not make 
sense. And if that can be done, why not the user can get the env form 
service client and create OM without factory?

I see no point in having a factory to share the env.

C++ does not need to be the same as Java. You can get the idea on the OO 
hierarchy from Java. But we are not building an equivalant. We already 
have most of the logic in C, so much of the Java stuff is already done. 
We just need an API for the user to use the C engine, that is it.
