At the time of writing, there are two versions of Jini: 1.0 and a version of 1.1. The core classes are all the same for versions 1.0 and 1.1. The only changes in version 1.1 for the programmer are that some classes from Jini 1.0 have been better specified and are in different packages, and some classes are new.
These are the main classes that have changed:
These are the main new classes:
If you get syntax or runtime errors relating to these classes, then it is possible that you are using Jini 1.0 instead of Jini 1.1.If you get "deprecated" warnings, then it is likely that you are using the Jini 1.0 classes in a Jini 1.1 environment. The old classes are supported for now, but are not approved.
