JavaSpaces™ Principles, Patterns, and Practice

1.5. Putting It All Together

Even though our “Hello World” example is simple, it demonstrates the key features of space-based programming and ties together many of the topics we've covered in this chapter. JavaSpaces technology is simple and expressive: with very little code (and only four lines that contain JavaSpace operations) we've implemented a simple distributed application that provides concurrent access to a shared resource (in this case a shared object). Because spaces provide a high-level coordination mechanism, we didn't need to worry about multithreaded server implementation, low-level synchronization issues, or network communication protocols—usual requirements of distributed application design. Instead, our example concretely illustrates ...
