The source code for all of the examples in this book is available online. On the World Wide Web, go to http://www.oreilly.com/catalog/javadc/. You can also retrieve the files via FTP (either with your web browser or another FTP client) at ftp://ftp.ora.com/published/oreilly/java/javadc/. I've tried to segregate the code into two groups of packages: utilities and examples. The dcj.utils packages include Java classes from the book that have potential for use in real applications. The dcj.examples packages include the code that's primarily explanatory in nature, but probably not of direct practical use in most situations.
Several of the examples will compile and run under either Java™ Developer's Kit ( JDK) 1.0 or 1.1; many of them, especially those based on RMI, require features from JDK 1.1. With a few exceptions, all that's required to run the examples is the standard JDK 1.1 API. The exceptions are the CORBA examples in Chapter 3, "Distributing Objects", which require JavaIDL or another CORBA environment for Java, and a few of the encryption examples in Chapter 5, "Security", which require the classes in the Java™ Cryptography Extension ( JCE) from Sun.
