JavaCheck
JavaCheck is a developer tool that ensures that applications and applets will be compatible with java platforms and can run on many types of devices. It does this by testing whether Java class files used by an application or applet conform to a particular Java platform API specification (such as the PersonalJava Specification).
Java Developer Connections
Register and Log In JDC and you will get JDC tech tips mail about every 10 days.
What is the Sun Developer Connection? The Sun Developer Connection (SDC) is Sun Microsystem's developer program designed specifically for Java and Solaris platform developers. The program offers technical articles, online training, early access software, newsletters, programming techniques, sample code, the Bug Parade, newsgroups, online discussion forums, searching, technical support, and more. If you're a registered JDC member, you're automatically a member of the SDC, and membership is free.
Java Foundation Classes(JFC) or Swing
Core to the Java platform, the Java Foundation Classes extend the original Abstract Windowing Toolkit (AWT) by adding a comprehensive set of graphical user interface class libraries that is completely portable and compatible with all AWT-based applications
Java HotSpot
The Java HotSpot virtual machine breaks new ground in nearly every area of virtual machine design. It provides significantly higher performance than any previous Java virtual machine. It uses a wide variety of techniques to gain performance, including on-the-fly adaptive optimization technology, which detects and accelerates performance-critical code. It provides ultra-fast thread synchronization, for maximum performance of thread-safe Java programs. It provides a garbage collector (GC) that is not only the fastest available by far, but which is also fully "accurate" (and therefore more reliable). Use of state-of-the-art algorithms dramatically reduces or eliminates user-perceivable garbage-collection pauses. Finally, at a source code level the Java HotSpot VM is written in a clean, high-level object-oriented design style that provides major improvements in maintainability and extensibility.
Java IDL ( JIDL )
Java IDL adds CORBA (Common Object Request Broker Architecture) capability to Java, providing standards-based interoperability and connectivity. Java IDL enables distributed Web-enabled Java applications to transparently invoke operations on remote network services using the industry standard OMG IDL (Object Management Group Interface Definition Language) and IIOP (Internet Inter-ORB Protocol) defined by the Object Management Group. Runtime components include a fully-compliant Java ORB for distributed computing using IIOP communication. The idltojava compiler generates portable client stubs and server skeletons that work with any CORBA-compliant ORB implementation.
Java JumpStart
The previous name is Java Developer's Companion.
The Java JumpStart CD-ROM is the essential resource for all Java application developers. It includes Sunís Java Development Kit (JDKTM), APIs, tools, online books, and documentation that every Java application developer needs to build 100% Pure Java applets, applications, and JavaBeansTM components.
The CD-ROM includes:
The Java Development Kit. Take full advantage of the Java programming language and APIs with Sunís award-winning JDK software. Includes the Java virtual machine, tools, core class libraries, and the freely redistributable Java Runtime Environment (subject to licensing terms). Build 100% Pure Java applications that are portable across all Java compatible systems.
Java Plug-in. Deploy Java applets across browsers in the enterprise using consistent, reliable, full-featured, Java Compatible runtime technology.
Java Standard Extensions. Enhance your applications with supplemental Java classes that extend the functionality of the core JDK software.
Tools and Utilities. Speed development and testing with useful tools and utilities.
Online Books. Learn about beginning through advanced Java technology topics from a selection of online versions of acclaimed Sunís Java Series Books.
Early Access Packages. Evaluate Sunís cutting-edge development kits and APIs before general release.
Sample Code. Increase your expertise of the Java programming language and its comprehensive set of APIs.
Coupons for discounts on hardcopy documentation, and more!
JavaOne
Sun's 1996, 1997, 1998 Worldwide Java Developer Conference, prepares developers to succeed in the rapidly growing Java industry by providing in-depth information on Java technologies and leaders in the Java industry.
Java Remote Method Invocation( RMI )
Remote Method Invocation (RMI) enables the programmer to create distributed Java-to-Java applications, in which the methods of remote Java objects can be invoked from other Java virtual machines, possibly on different hosts. A Java program can make a call on a remote object once it obtains a reference to the remote object, either by looking up the remote object in the bootstrap naming service provided by RMI or by receiving the reference as an argument or a return value. A client can call a remote object in a server, and that server can also be a client of other remote objects. RMI uses Object Serialization to marshal and unmarshal parameters and does not truncate types, supporting true object-oriented polymorphism.
Object Serialization extends the core Java Input/Output classes with support for objects. Object Serialization supports the encoding of objects and the objects reachable from them into a stream of bytes and it supports the complementary reconstruction of the object graph from the stream. Serialization is used for lightweight persistence and for communication via sockets or Remote Method Invocation (RMI). The default encoding of objects protects private and transient data, and supports the evolution of the classes. A class may implement its own external encoding and is then solely responsible for the external format.
JavaSpaces
JavaSpaces technology provides a cooperative marketplace for posting and retrieving groups of related objects across a network. "Buyers" and "Sellers" dynamically post their requests and/or services to a JavaSpace and receive a response from interested parties. JavaSpaces is not interested in who is posting what; it is based simply on a value-matching lookup routine for specified fields. JavaSpaces is based on Java, and implements the RMI extension. It is a simple, fast, and unified mechanism for sharing coordinating, and communicating distributed resources, services, and objects across a network.
JavaServer Toolkit
The Toolkit is attractive to such developers for several reasons. These include improving their time-to-market for server-side Java products, by providing features such as:
A network and threading framework which supports both connection and datagram based protocols;
Dynamic web-based remote administration; Identity based access controls ;
Realm based authentication.
Server side "sandboxes" for dynamically loaded extensions;
A container for Java servlet beans
Support for the Java Servlet 1.1 API.
SSL for strong cryptographic privacy and authentication (as allowed by use export regulations).
An HTTP 1.0 based web engine with keep-alive support; Web-page compilation using which HTML pages come alive; Client session management.
