This library enables Java applications to work with property lists in various formats. Supported formats for reading and writing are OS X/iOS binary and XML property lists. ASCII property lists are also supported. The library also provides access to basic functions of NeXTSTEP/Cocoa classes like NSDictionary, NSArray, etc.

There is a newer version: 1.28
