78-432: WebObjects is a discontinued Java web application server and a server-based web application framework originally developed by NeXT Software, Inc. WebObject's hallmark features are its object-orientation , database connectivity, and prototyping tools. Applications created with WebObjects can be deployed as web sites, Java WebStart desktop applications, and/or standards-based web services . The deployment runtime
156-461: A layered architecture to promote caching to reduce user-perceived latency , enforce security , and encapsulate legacy systems . REST has been employed throughout the software industry to create stateless , reliable web-based applications . An application that adheres to the REST architectural constraints may be informally described as RESTful , although this term is more commonly associated with
234-673: A trademark search revealed that Oak Technology used the name Oak . Sun priced Java licenses below cost to gain market share. Although Java 1.0a became available for download in 1994, the first public release of Java, Java 1.0a2 with the HotJava browser, came on May 23, 1995, announced by Gage at the SunWorld conference. Accompanying Gage's announcement, Marc Andreessen , Executive Vice President of Netscape Communications Corporation , unexpectedly announced that Netscape browsers would include Java support. On January 9, 1996, Sun Microsystems formed
312-446: A virtual machine ), a compiler and a set of libraries ; there may also be additional servers and alternative libraries that depend on the requirements. Java platforms have been implemented for a wide variety of hardware and operating systems with a view to enable Java programs to run identically on all of them. The Java platform consists of several programs, each of which provides a portion of its overall capabilities. For example,
390-647: A challenging and error-prone task. The team also worried about the C++ language's lack of portable facilities for security, distributed programming , and threading . Finally, they wanted a platform that would port easily to all types of devices. Bill Joy had envisioned a new language combining Mesa and C. In a paper called Further , he proposed to Sun that its engineers should produce an object-oriented environment based on C++. Initially, Gosling attempted to modify and extend C++ (a proposed development that he referred to as "C++ ++ --") but soon abandoned that in favor of creating
468-428: A database, perhaps to check relationships or to seed the database with data. The user interface is generated dynamically, on-the-fly at runtime using a rules-based system—no code is generated. Consequently, one can modify an application's configuration at runtime (using an assistant program) without recompiling or relaunching the application. Developers can utilize one of three different technologies, depending upon
546-518: A license key for development or deployment. WebObjects transitioned from a stand-alone product to be a part of Mac OS X with the release of version 5.3 in June 2005. The developer tools and frameworks, which previously sold for US$ 699, were bundled with Apple's Xcode IDE . Support for other platforms, such as Windows , was then discontinued. Apple said that it would further integrate WebObjects development tools with Xcode in future releases. This included
624-407: A lot of leeway to implementors regarding the implementation details. Since Java 1.3, JRE from Oracle contains a JVM called HotSpot. It has been designed to be a high-performance JVM. To speed-up code execution, HotSpot relies on just-in-time compilation. To speed-up object allocation and garbage collection, HotSpot uses generational heap. The Java virtual machine heap is the area of memory used by
702-551: A new EOModeler Plugin for Xcode. This strategy, however, was not pursued further. In 2006, Apple announced the deprecation of Mac OS X's Cocoa-Java bridge with the release of Xcode 2.4 at the August 2006 Worldwide Developers Conference, and with it all dependent features, including the entire suite of WebObjects developer applications: EOModeler, EOModeler Plugin, WebObjects Builder, WebServices Assistant, RuleEditor and WOALauncher. Apple had decided to concentrate its engineering resources on
780-513: A new language, which he called Oak , after the tree that stood just outside his office. By the summer of 1992, the team could demonstrate portions of the new platform, including the Green OS , the Oak language, the libraries, and the hardware. Their first demonstration, on September 3, 1992, focused on building a personal digital assistant (PDA) device named Star7 that had a graphical interface and
858-610: A proposal for a set-top box platform. However, the cable industry felt that their platform gave too much control to the user, so Firstperson lost their bid to SGI . An additional deal with The 3DO Company for a set-top box also failed to materialize. Unable to generate interest within the television industry, the company was rolled back into Sun. In June and July 1994 – after three days of brainstorming with John Gage (the Director of Science for Sun), Gosling, Joy, Naughton, Wayne Rosing , and Eric Schmidt –

Any such request will in turn receive the representation of a resource, and so on. An important consequence is that the only identifier that needs to be known is
1014-466: A short delay during loading and once they have "warmed up" by being all or mostly JIT-compiled, tend to run about as fast as native programs. Since JRE version 1.2, Sun's JVM implementation has included a just-in-time compiler instead of an interpreter. Although Java programs are cross-platform or platform independent, the code of the Java Virtual Machines (JVM) that execute these programs
1092-610: A small office on Sand Hill Road in Menlo Park, California . They aimed to develop new technology for programming next-generation smart appliances, which Sun expected to offer major new opportunities. The team originally considered using C++, but rejected it for several reasons. Because they were developing an embedded system with limited resources, they decided that C++ needed too much memory and that its complexity led to developer errors. The language's lack of garbage collection meant that programmers had to manually manage system memory,

In November of that year, the Green Project was spun off to become Firstperson , a wholly owned subsidiary of Sun Microsystems, and the team relocated to Palo Alto, California . The Firstperson team had an interest in building highly interactive devices, and when Time Warner issued a request for proposal (RFP) for a set-top box , Firstperson changed their target and responded with
1248-501: A standard interface for the Java applications to perform those tasks. Finally, when some underlying platform does not support all of the features a Java application expects, the class libraries work to gracefully handle the absent components, either by emulation to provide a substitute, or at least by providing a consistent way to check for the presence of a specific feature. The word "Java", alone, usually refers to Java programming language that
1326-630: A supported version. Oracle released the last free-for-commercial-use public update for the legacy Java 8 LTS in January 2019, and will continue to support Java 8 with public updates for personal use indefinitely. Oracle extended support for Java 6 ended in December 2018. The Java platform is a suite of programs that facilitate developing and running programs written in the Java programming language. A Java platform includes an execution engine (called
1404-530: A very simple memory model where objects are allocated on the heap (while some implementations e.g. all currently supported by Oracle, may use escape analysis optimization to allocate on the stack instead) and all variables of object types are references . Memory management is handled through integrated automatic garbage collection performed by the JVM. The latest version is Java 22 released in March 2024, and
1482-546: Is a software architectural style that was created to guide the design and development of the architecture for the World Wide Web . REST defines a set of constraints for how the architecture of a distributed, Internet -scale hypermedia system, such as the Web, should behave. The REST architectural style emphasises uniform interfaces , independent deployment of components , the scalability of interactions between them, and creating
1560-480: Is a JIT (Just In Time) compiler within the Java Virtual Machine , or JVM. The JIT compiler translates the Java bytecode into native processor instructions at run-time and caches the native code in memory during execution. The use of bytecode as an intermediate language permits Java programs to run on any platform that has a virtual machine available. The use of a JIT compiler means that Java applications, after

Java is used in a wide variety of computing platforms from embedded devices and mobile phones to enterprise servers and supercomputers . Java applets , which are less common than standalone Java applications, were commonly run in secure, sandboxed environments to provide many features of native applications through being embedded in HTML pages.

The organization last held a Worldwide WebObjects Developer Conference, WOWODC, in 2013. In May 2016, Apple confirmed that WebObjects had been discontinued. As of 2016 most WebObjects architects and engineers are using the tools being developed by
1794-467: Is built on top of the core WebObjects frameworks and which extends them. For example, Project Wonder has updated development tools and provides a REST framework that was not part of the original WebObjects package. Though once included in the default installation of Mac OS X Server, WebObjects was no longer installed by default starting with Mac OS X Snow Leopard Server and shortly after, Apple ceased promoting or selling WebObjects. As of 2016, WebObjects
1872-789: Is instead maintained by an online community of volunteers. This community calls it "Project Wonder". WebObjects was created by NeXT Software, Inc. , first publicly demonstrated at the Object World conference in 1995 and released to the public in March 1996. The time and cost benefits of rapid, object-oriented development attracted major corporations to WebObjects in the early days of e-commerce , with clients including BBC News , Dell Computer , Disney , DreamWorks SKG , Fannie Mae , GE Capital , Merrill Lynch , and Motorola . Following NeXT 's merger into Apple Inc. in 1997, WebObjects' public profile languished. Many early adopters later switched to alternative technologies, including Apple which had been

It implements the Java Language Specification (JLS) and the Java Virtual Machine Specification (JVMS) and provides the Standard Edition (SE) of the Java Application Programming Interface (API). It is derivative of the community driven OpenJDK which Oracle stewards. It provides software for working with Java applications. Examples of included software are

Because the Java platform is not dependent on any specific operating system, applications cannot rely on any of the pre-existing OS libraries. Instead, the Java platform provides a comprehensive set of its own standard class libraries containing many of

One can use the included WebObjects Java SE application server or deploy on third-party Java EE application servers such as JBoss , Apache Tomcat , WebLogic Server or IBM WebSphere . WebObjects was maintained by Apple for quite a while. However, because Apple has stopped maintaining the software, it now
2184-451: Is similar in purpose to the JVM. Like the JVM, the CLR provides memory management through automatic garbage collection, and allows .NET byte code to run on multiple operating systems. .NET included a Java-like language first named J++ , then called Visual J# that was incompatible with the Java specification. It was discontinued 2007, and support for it ended in 2015. The JVM specification gives
2262-493: The .NET Framework , appearing since 2002, which incorporates many of the successful aspects of Java. .NET was built from the ground-up to support multiple programming languages, while the Java platform was initially built to support only the Java language, although many other languages have been made for JVM since. Like Java, .NET languages compile to byte code and are executed by the Common Language Runtime (CLR), which
2340-535: The Java compiler , which converts Java source code into Java bytecode (an intermediate language for the JVM), is provided as part of the Java Development Kit (JDK). The Java Runtime Environment (JRE), complementing the JVM with a just-in-time (JIT) compiler , converts intermediate bytecode into native machine code on the fly. The Java platform also includes an extensive set of libraries. The essential components in

In addition, several languages have been designed to run natively on the JVM, including Clojure , Groovy , and Scala . Java syntax borrows heavily from C and C++ , but object-oriented features are modeled after Smalltalk and Objective-C . Java eschews certain low-level constructs such as pointers and has

The Java Runtime Environment (JRE) released by Oracle is a freely available software distribution containing a stand-alone JVM (HotSpot), the Java standard library ( Java Class Library ), a configuration tool, and—until its discontinuation in JDK 9—a browser plug-in. It is the most common Java environment installed on personal computers in

It was bundled with a database manager and facilitates the use of scripting languages with the JVM (such as JavaScript using Mozilla 's Rhino engine). As of this version, Sun replaced the name "J2SE" with Java SE and dropped the ".0" from the version number. Other major changes include support for pluggable annotations ( JSR 269 ), many GUI improvements, including native UI enhancements to support
2652-523: The C++/ C programming languages. Engineer Patrick Naughton had become increasingly frustrated with the state of Sun's C++ and C application programming interfaces (APIs) and tools, as well as with the way the NeWS project was handled by the organization. Naughton informed Scott McNealy about his plan of leaving Sun and moving to NeXT ; McNealy asked him to pretend he was God and send him an e-mail explaining how to fix
2730-606: The Design of Network-based Software Architectures" at UC Irvine . To create the REST architectural style, Fielding identified the requirements that apply when creating a world-wide network-based application, such as the need for a low entry barrier to enable global adoption. He also surveyed many existing architectural styles for network-based applications, identifying which features are shared with other styles, such as caching and client–server features, and those which are unique to REST, such as
2808-408: The JVM for dynamic memory allocation . In HotSpot the heap is divided into generations : The permanent generation (or permgen ) was used for class definitions and associated metadata prior to Java 8. Permanent generation was not part of the heap. The permanent generation was removed from Java 8. Originally there was no permanent generation, and objects and classes were stored together in

(Instead, Google 's Android development tools take Java programs as input and output Dalvik bytecode, which is the native input format for the virtual machine on Android devices.) The last Critical Path Update version of JRE with an Oracle BCL Agreement was 8u201 and, the last Patch Set Update version with the same license was 8u202. The last Oracle JRE implementation, regardless of its licensing scheme,

Some of these are for existing languages, while others are for extensions to the Java language. These include: The success of Java and its write once, run anywhere concept has led to other similar efforts, notably
3042-545: The Java libraries provide the programmer a well-known set of functions to perform common tasks, such as maintaining lists of items or performing complex string parsing. Second, the class libraries provide an abstract interface to tasks that would normally depend heavily on the hardware and operating system. Tasks such as network access and file access are often heavily intertwined with the distinctive implementations of each platform. The java.net and java.io libraries implement an abstraction layer in native OS code, then provide

This version is not officially supported on the Windows XP platform, but is known to work there. Thus, due to the end of Java 7's lifecycle it is the recommended version for XP users. Previously, only an unofficial manual installation method had been described for Windows XP SP3. It refers to JDK8,

For instance, several experimental extensions had been added to the communication protocol (HTTP) to support proxies , and more extensions were being proposed, but there was a need for a formal Web architecture with which to evaluate the impact of these changes. The W3C and IETF working groups together started work on creating formal descriptions of
3510-486: The Web's three primary standards: URI , HTTP , and HTML . Roy Fielding was involved in the creation of these standards (specifically HTTP 1.0 and 1.1, and URI), and during the next six years he created the REST architectural style, testing its constraints on the Web's protocol standards and using it as a means to define architectural improvements — and to identify architectural mismatches. Fielding defined REST in his 2000 PhD dissertation "Architectural Styles and

The Java language has undergone several changes since the release of JDK ( Java Development Kit ) 1.0 on January 23, 1996, as well as numerous additions of classes and packages to the standard library . Since J2SE 1.4 the Java Community Process (JCP) has governed the evolution of the Java Language. The JCP uses Java Specification Requests (JSRs) to propose and specify additions and changes to
3900-779: The community in its efforts to extend such tools and develop new ones. In a posting to the webobjects-dev mailing list, Daryl Lee from Apple's WebObjects team publicly disclosed the company's new strategy for WebObjects. It promised to "make WebObjects the best server-side runtime environment" by: WebObjects 5.4, which shipped with Mac OS X Leopard in October 2007, removed the license key requirement for both development and deployment of WebObjects applications on all platforms. All methods for checking license limitations were then deprecated. In 2009, Apple stopped issuing new releases of WebObjects outside Apple. The community decided to continue development with Project Wonder, an open-source framework which

McNealy forwarded the message to other important people at Sun, and the Stealth Project started. The Stealth Project was soon renamed to the Green Project , with James Gosling and Mike Sheridan joining Naughton. Together with other engineers, they began work in

#17328523527924056-400: The concept of resources. Fielding was trying to both categorise the existing architecture of the current implementation and identify which aspects should be considered central to the behavioural and performance requirements of the Web. By their nature, architectural styles are independent of any specific implementation, and while REST was created as part of the development of the Web standards,
4134-684: The core classes. A Java Plug-in was released, and Sun's JVM was equipped with a JIT compiler for the first time. J2SE 1.3 (May 8, 2000) – Codename Kestrel . Notable changes included the bundling of the HotSpot JVM (the HotSpot JVM was first released in April, 1999 for the J2SE ;1.2 JVM), JavaSound , Java Naming and Directory Interface (JNDI) and Java Platform Debugger Architecture (JPDA). J2SE 1.4 (February 6, 2002) – Codename Merlin . This became

The term representational state transfer was introduced and defined in 2000 by computer scientist Roy Fielding in his doctoral dissertation. It means that
4290-463: The developer's own custom code. WebObjects' frameworks can be broken down into three core parts: WebObjects features a set of rapid development technologies that can automatically create a Web application without the need to write any Java code. Given a model file for a database, WebObjects will create an interface supporting nine common database tasks, including querying, editing and listing. Such applications are useful for prototyping or administering

Java 8 is supported on Windows Server 2008 R2 SP1, Windows Vista SP2 and Windows 7 SP1, Ubuntu 12.04 LTS and higher (and some other OSes). Java SE 9 and 10 have higher system requirements, i.e. Windows 7 or Server 2012 (and web browser minimum certified is upped to Internet Explorer 11 or other web browsers), and Oracle dropped 32-bit compatibility for all platforms, i.e. only Oracle's " 64-bit Java virtual machines (JVMs) are certified".

In 2013 Kaspersky Labs reported that the Java plug-in was the method of choice for computer criminals. Java exploits are included in many exploit packs that hackers deploy onto hacked web sites. Java applets were removed in Java 11, released on September 25, 2018. The Java platform and language began as an internal project at Sun Microsystems in December 1990, providing an alternative to

Developed under JSR 176, Tiger added several significant new language features including
4602-426: The identifier of the first resource requested, and all other identifiers will be discovered. This means that those identifiers can change without the need to inform the client beforehand and that there can be only loose coupling between client and server. The Web began to enter everyday use in 1993–1994, when websites for general use started to become available. At the time, there was only a fragmented description of
4680-584: The implementation of the Web does not obey every constraint in the REST architectural style. Mismatches can occur due to ignorance or oversight, but the existence of the REST architectural style means that they can be identified before they become standardised. For example, Fielding identified the embedding of session information in URIs as a violation of the constraints of REST which can negatively affect shared caching and server scalability. HTTP cookies also violated REST constraints because they can become out of sync with

Mobile phones including feature phones and early smartphones that ship with a JVM are most likely to include a JVM meant to run applications targeting Micro Edition of the Java platform. Meanwhile, most modern smartphones, tablet computers , and other handheld PCs that run Java apps are most likely to do so through support of the Android operating system , which includes an open source virtual machine incompatible with

WebObjects was part of Apple's strategy of using software to drive hardware sales, and in 2000 the price was lowered from $ 50,000 (for the full deployment license) to $ 699. From May 2001, WebObjects was included with Mac OS X Server , and no longer required
4914-827: The latest long-term support (LTS) version is Java 21 released in September 2023, which is one of a few LTS versions still supported, down to Java 8 LTS. As an open source platform, Java has many distributors, including Amazon , IBM , Azul Systems , and AdoptOpenJDK . Distributions include Amazon Corretto, Zulu, AdoptOpenJDK, and Liberica. Regarding Oracle, it distributes Java 8, and also makes available e.g. Java 11, both also currently supported LTS versions. Oracle (and others) "highly recommend that you uninstall older versions of Java" than Java 8, because of serious risks due to unresolved security issues. Since Java 9 (as well as versions 10, and 12–16, and 18–20) are no longer supported, Oracle advises its users to "immediately transition" to

Java SE
5148-477: The runtime engine of WebObjects, leaving the future responsibility for developer applications with the open-source community. The main open-source alternative — the Eclipse IDE with the WOLips suite of plugins — had matured to such an extent that its capabilities had, in many areas, surpassed those of Apple's own tools, which had not seen significant updates for a number of years. Apple promised to provide assistance to
5226-495: The same area. But as class unloading occurs much more rarely than objects are collected, moving class structures to a specific area allowed significant performance improvements. The Java JRE is installed on a large number of computers. End users with an out-of-date version of JRE therefore are vulnerable to many known attacks. This led to the widely shared belief that Java is inherently insecure. Since Java 1.7, Oracle's JRE for Windows includes automatic update functionality. Before
5304-465: The same reusable functions commonly found in modern operating systems. Most of the system library is also written in Java. For instance, the Swing library paints the user interface and handles the events itself, eliminating many subtle differences between how different platforms handle components. The Java class libraries serve three purposes within the Java platform. First, like other standard code libraries,

They felt that with the advent of graphical web browsers like Mosaic the Internet could evolve into the same highly interactive medium that they had envisioned for cable TV. As a prototype, Naughton wrote a small browser, WebRunner (named after the movie Blade Runner ), renamed HotJava in 1995. Sun renamed the Oak language to Java after
