API - Extensions by Sun Microsystems

• JFC (Java Foundation Classes)
  That is where Swing comes from. For more info see The Swing Connection.
• Java^TM Media Framework
  The Java Media Framework (JMF) 1.0 API specifies a simple, unified architecture, messaging protocol, and programming interface for media playback. This API was developed by Sun Microsystems, Inc., Silicon Graphics Inc., and Intel Corporation.
  The Java Media Framework (JMF) 2.0 API extends the 1.0 API by providing capture functionality, pluggable codecs, file saving, RTP broadcast and the ability to access and manipulate media data before it is rendered. This API is available for public review, and was developed by Sun Microsystems, Inc. and IBM.
• Java^TM Advanced Imaging
  The Java Advanced Imaging (JAI) API is the extensible, network-aware programming interface for creating advanced image processing applications and applets in the Java programming language. The Java Advanced Imaging API offers a rich set of image processing features such as tiling, deferred execution and multiprocessor scalability. Fully compatible with the Java 2D API, developers can easily extend the image processing capabilities and performance of standard Java 2D applications with the Java Advanced Imaging API.
• Java^TM Serial Port (COMM)
  The Java Serial Port can be used to write platform-independent communications applications for technologies such as voice mail, fax, and smartcards. Its current version supports RS232 serial ports and IEEE 1284 parallel ports.
• Java 3D^TM
  The Java 3DTM 1.1 API is a set of classes for writing three-dimensional graphics applications and 3D applets. It gives developers high level constructs for creating and manipulating 3D geometry and for constructing the structures used in rendering that geometry. Application developers can describe very large virtual worlds using these constructs, which provides Java 3D with enough information to render these worlds efficiently.
• JavaMail
  The JavaMail API provides a set of abstract classes that models a mail system. The API is meant to provide a platform independent and protocol independent framework to build Java-based mail and messaging applications.
• JavaHelp^TM
  JavaHelp is the Help system for the Java platform: it is a Java-based, platform independent help system that enables Java developers to incorporate online help for a variety of needs, including Java components, applications (network and stand-alone), desktops, and HTML pages.
• JavaBeans^TM Activation Framework (JAF)
  With the JavaBeans Activation Framework (JAF) developers can take advantage of standard services to determine the type of an arbitrary piece of data, encapsulate access to it, discover the operations available on it and to instantiate the appropriate JavaBeans component to perform these operations.
• Java^TM Servlet
  Java Servlet provides a uniform, industry-supported interface for extending a web server with cross-platform and cross-server components written in the Java Programming Language.
• Java^TM Cryptography (JCE)
  The Java Cryptography Extension (JCE) 1.2 provides a framework and implementations for encryption, key generation and key agreement, and Message Authentication Code (MAC) algorithms. Support for encryption includes symmetric, asymmetric, block, and stream ciphers. The software also supports secure streams and sealed objects.
• InfoBus
  InfoBus enables dynamic exchange of data between JavaBeans components by defining a small number of interfaces between cooperating Beans and specifying the protocol for use of those interfaces.
  The protocols are based on a notion of an information bus. All components which implement these interfaces can plug into the bus. As a member of the bus any component can exchange data with any other component in structured way, including arrays, tables, and database rowsets.
• Java Naming and Directory Interface^TM (JNDI)
  Provides uniform, industry-standard, seamless connectivity from the Java platform to business information assets, thus allowing developers to deliver Java applications with unified access to multiple naming and directory services across the enterprise.
• The XML Project
  Sun´s home for combining XML and Java Technology

Third Party packages...

• JGL (Java Generic Library)
  A collection API implementation including linked lists etc. The Collection API before invention of CollectionAPI in JDK1.2.
• XML4J
  XML Parser for java from IBM.
