The Jini(TM) Technology Lookup, Discovery, and Join Compatibility Kit (LDJ Kit), produced by Sun Microsystems, Inc., is a freely available code and documentation bundle that can be used to qualify certain characteristics of hardware or software based on Jini network technology (Jini technology).
The purpose of compatibility testing is to ensure that programs are good citizens in the environment of Jini technology-enabled services and/or devices (good lookup citizens). To be a good lookup citizen, a program must interoperate with other good lookup citizens and behave in a way that doesn't cause trouble for the rest of the networks, such as swamping a network with too much traffic. The rules of good citizenship are detailed in the Jini technology specifications and are, to a lesser extent, codified in the LDJ Kit.
The LDJ Kit software consists of a test framework and a set of tests that verify that a Jini technology-enabled program meets certain aspects of the core specifications. Note that a single LDJ Kit installation can test clients, services, and lookup services.
This kit may not be used to fulfill any compliance requirements for code licensed under the Sun Community Source License v3.0/Jini Technology Specific Attachment v1.0 (SCSL3/Jini TSA 1.0).
