Two printed books of the online documentation from JavaSoft are currently available in bookstores: The "Java Class Libraries: An Annotated Reference" has examples for every class member, while "The Java Application Programming Interface" (Vol. 1 & 2) is based on javadoc-generated documentation. 

JDK 1.1 API

The JDK 1.1 is the latest release of the Java Development Kit. It is a superset of JDK 1.0.2 that brings improvements in functionality, performance and quality to Java. 

See JDK-Related Technology for information about Java IDL, Native Threads, and other core technology that is related to the JDK.

JAVA ENTERPRISE API

Java Enterprise APIs support connectivity to enterprise databases and legacy applications. With these APIs, corporate developers are building distributed client/server applets and applications in Java that run on any OS or hardware platform in the enterprise. Java Enterprise currently encompasses four areas: JDBC^TM, Java IDL, Java RMI and JNDI^TM. 

JDBC^TM is Java Database Connectivity, a standard SQL database access interface, providing uniform access to a wide range of relational databases. 

See JDBC web pages for more information beyond what is given in the following table.

Java IDL is developed to the OMG Interface Definition Language specification, as a language-neutral way to specify an interface between an object and its client on a different platform. 

In order to provide sufficient time to standardize Java-to-CORBA connectivity through OMG, Java IDL has been be decoupled from the JDK 1.1 release and will be available on a slightly delayed schedule. Java IDL, implemented completely in Java, will work seamlessly on top of JDK 1.1 when it is available.

Java Naming and Directory Interface (JNDI) is a new addition to JavaSoft platform APIs. It provides Java applications a unified interface to multiple naming and directory services in the enterprise. As part of the Java Enterprise API set, JNDI enables seamless connectivity to heterogeneous enterprise naming and directory services. Java developers can now build powerful and portable directory-enabled applications using this industry-standard interface.

JAVABEANS^TM API

The JavaBeans^TM APIs define a portable, platform-neutral set of APIs for software components. JavaBean components will be able to plug into existing component architectures such as Microsoft's OLE/COM/Active-X architecture, OpenDoc, and Netscape's LiveConnect. End users will be able to compose together JavaBeans components using application builders. For example, a button component could trigger a bar chart to be drawn in another component, or a live data feed component could be represented as a chart in another component. 

JavaBeans is now available in JDK 1.1. Beans developers will also need to download the Beans Development Kit from the JavaBeans web pages

JAVA SECURITY API

The Java Security APIs are a framework for developers to easily and securely include security functionality in their applets and applications. This functionality includes cryptography with digital signatures, encryption, and authentication. 

An intermediate subset of the Security API is included in JDK 1.1. This subset is known as "Security and Signed Applets". 

See Java Security web pages for further information beyond what is given in the table below.

JAVA SERVER API

Java Server API is an extensible framework that enables and eases the development of a whole spectrum of Java-powered Internet and intranet servers. The APIs provide uniform and consistent access to the server and administrative system resources required for developers to quickly develop their own Java `servlets' - executable programs that users upload to run on networks or servers.

JAVA EMBEDDED API

The Java Embedded APIs specify how the Java API may be subsetted for embedded devices that are incapable of supporting the full Java Core API. It includes a minimal embedded API based on java.lang, java.util and parts of java.io. It then defines a series of extensions for particular areas such as networking and GUIs. 

This API proposal will be released for public review at a time to be determined. 

Glossary

• Library Type - Each set of API belongs to the Core, is a Standard Extension, or is a mixture: 
• Core is the minimal set of API that developers can assume is present on all delivered implementations of the Java Platform, once the final API is released by JavaSoft. (The Embedded Java Platform is the single exception, which can run on smaller, dedicated, embedded systems such as printers, copiers and cellular phones.) The Core API grows over time; the current core API is based on JDK 1.0; the next will be based on JDK 1.1. 
• Standard Extension is API outside the Core API for which JavaSoft has defined and published an API standard. The current Standard Extensions are defined in this document. Over time, as the platform develops, some of the Standard Extensions may migrate into the Core API. 
• Core / Standard Extension means some of the API in a set is Core and the rest is shipped separately as a Standard Extension. 

• API Spec Available to Public: This is the date the preliminary API specification is planned to be released to the general public for review. Specifications will be available through links on this page. The specifications may evolve after this date. 
• Early Access Implementation: This is the date the implemented libraries are planned to first be available to the general public, from links on this page. Some implementations will be available as part of a JDK, while others will be available separately, at our discretion. 
• Final Implementation: This is the date the final implementation is planned to be released to the general public, available through links on this page.
