There is some info out there suggesting that it is possible to use CORBA on Android, concretely with Jacorb.
However, it seems that officially there is no support for such thing.
Is there any fork of JacORB that supports it? Are there any other open source Java ORBs that work on Android?
JacORB 2 could be compiled without rmi option for Android. JacORB 3 needs to be patched. See this thread for further information or post to the JacORB mailing list.
