Java 1.1 provides a number of important new features that are loosely grouped under the name "Enterprise APIs." These include JDBC (Java DataBase Connectivity), RMI (Remote Method Invocation), and Java Security. With release 1.1, Java has grown too big for all of it to be documented, even in quick-reference format, in a single volume. Therefore, the JDBC, RMI, and Security packages will be documented, along with other, forthcoming Enterprise APIs, in a separate volume, Java Enterprise in a Nutshell. Note, however, that while this volume does not cover the Java Security API, it does cover applet security, signed applets, and the javakey program that is used to create digital signatures, generate key pairs, and manage a database of entities and their keys.
