JAXB
Jakarta XML Binding (JAXB; formerly Java Architecture for XML Binding) is a software framework that allows Java EE developers to map Java classes to XML representations. JAXB provides two main features: the ability to ''marshal'' Java objects into XML and the inverse, i.e. to ''unmarshal'' XML back into Java objects. In other words, JAXB allows storing and retrieving data in memory in any XML format, without the need to implement a specific set of XML loading and saving routines for the program's class structure. It is similar to xsd.exe and XmlSerializer in the .NET Framework. JAXB is particularly useful when the specification is complex and changing. In such a case, regularly changing the XML Schema definitions to keep them synchronised with the Java definitions can be time-consuming and error-prone. JAXB is one of the APIs in the Jakarta EE platform (formerly Java EE), part of the Java Web Services Development Pack (JWSDP), and one of the foundations for WSIT. It was also ...

Marshalling (computer Science)
In computer science, marshalling or marshaling ( US spelling) is the process of transforming the memory representation of an object into a data format suitable for storage or transmission, especially between different runtimes. It is typically used when data must be moved between different parts of a computer program or from one program to another. Marshalling simplifies complex communications, because it allows using '' composite objects'' instead of being restricted to '' primitive objects''. Comparison with serialization Marshalling is similar to or synonymous with serialization, although technically serialization is one step in the process of marshalling an object. * Marshalling is describing the overall intent or process to transfer some ''live'' object from a client to a server (with ''client'' and ''server'' taken as abstract, mirrored concepts mapping to any matching ends of an arbitrary communication link ie. sockets). The point with marshalling an object is to h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Java Community Process
The Java Community Process (JCP), established in 1998, is a formal mechanism that enables interested parties to develop standard technical specifications for Java technology. Becoming a member of the JCP requires solid knowledge of the Java programming language, its specifications, and best practices in software development. Membership in the JCP involves a detailed review of the candidate's profile, including an assessment by current members. Typically, professionals are invited to join the JCP based on their contributions and reputation within the Java community. Once invited, the new member undergoes an evaluation by the JCP Executive Committee, ensuring that they can effectively contribute to the Java Specification Requests (JSRs). These formal documents describe proposed specifications and technologies to be added to the Java (software platform), Java platform. New members are encouraged to engage actively and play a crucial role in supporting the Java community and its release ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
JiBX
JiBX is an open-source Java framework for XML data binding. It solves the same problem as tools such as JAXB, XMLBeans and JDOM, but uses an alternate approach. It lets developers work with data from XML documents using arbitrarily defined Plain Old Java Objects (POJOs). The JiBX framework uses a binding definition to tell it how the Java objects map to the XML and vice versa. It is designed to perform the translation between internal data structures and XML with very high efficiency, and has been claimed to be the fastest XML data binding framework for Java. JiBX differs from other Java-XML transformation tools such as JAXB, XMLBeans and JDOM in that it is not based on code generation but on "Mapped Data Binding". In other words, the Java class and the XML document being mapped are both treated as first class objects and one is not generated from the other. This approach decouples the domain model (Java) from the service interface (input and output XML documents) in a way that ...

XMLBeans
XMLBeans is a Java-to- XML binding framework which is part of the Apache Software Foundation XML project. Description XMLBeans is a tool that allows access to the full power of XML in a Java friendly way. The idea is to take advantage of the richness and features of XML and XML Schema and have these features mapped as naturally as possible to the equivalent Java language and typing constructs. XMLBeans uses XML Schema to compile Java interfaces and classes that can then be used to access and modify XML instance data. Using XMLBeans is similar to using any other Java interface/class: with methods like getFoo or setFoo, just as when working with Java. While a major use of XMLBeans is to access XML instance data with strongly typed Java classes there are also APIs that allow access to the full XML infoset (XMLBeans keeps XML Infoset fidelity) as well as to allow reflection into the XML schema itself through an XML Schema Object model. Characteristics of XMLBeans # Large XML Schema ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
EclipseLink
EclipseLink is the open source Eclipse Persistence Services Project from the Eclipse Foundation. The software provides an extensible framework that allows Java developers to interact with various data services, including databases, web services, Object XML mapping (OXM), and enterprise information systems (EIS). EclipseLink supports a number of persistence standards including: * Jakarta Persistence (JPA) *Jakarta XML Binding (JAXB) * Jakarta Connectors (JCA) * Service Data Objects (SDO) EclipseLink is based on the TopLink product from which Oracle contributed the source code to create the EclipseLink project. The original contribution was from TopLink's 11g code base, and the entire code-base/feature set was contributed, with only EJB 2 Container-Managed Persistence (CMP) and some minor Oracle Application Server specific integration removed. This differs from the TopLink Essentials GlassFish contribution, which did not include some key enterprise features. The package names ...

Web Services Description Language
The Web Services Description Language (WSDL ) is an XML-based interface description language that is used for describing the functionality offered by a web service. The acronym is also used for any specific WSDL description of a web service (also referred to as a ''WSDL file''), which provides a machine-readable description of how the service can be called, what parameters it expects, and what data structures it returns. Therefore, its purpose is roughly like a type signature in a programming language. The latest version of WSDL, which became a W3C recommendation in 2007, is WSDL 2.0. The meaning of the acronym has changed from version 1.1 where the "D" stood for "Definition". Description The WSDL describes services as collections of network Communication endpoint, endpoints, or Port (computer networking), ports. The WSDL specification provides an XML File format, format for documents for this purpose. The abstract definitions of ports and messages are separated from their conc ...

Web Services Interoperability Technology
Web Services Interoperability Technology (WSIT) is an open-source project started by Sun Microsystems to develop the next-generation of Web service technologies. It provides interoperability between Java Web Services and Microsoft's Windows Communication Foundation (WCF). It consists of Java programming language APIs that enable advanced WS-* features to be used in a way that is compatible with Microsoft's Windows Communication Foundation as used by .NET. The interoperability between different products is accomplished by implementing a number of Web Services specifications, like JAX-WS that provides interoperability between Java Web Services and Microsoft Windows Communication Foundation. WSIT is currently under development as part of Eclipse Metro. WSIT is a series of extensions to the basic SOAP protocol, and so uses JAX-WS and JAXB. It is not a new protocol such as the binary DCOM. WSIT implements the WS-I specifications, including: *Metadata **WS-MetadataExchange WS- ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Java (programming Language)
Java is a High-level programming language, high-level, General-purpose programming language, general-purpose, Memory safety, memory-safe, object-oriented programming, object-oriented programming language. It is intended to let programmers ''write once, run anywhere'' (Write once, run anywhere, WORA), meaning that compiler, compiled Java code can run on all platforms that support Java without the need to recompile. Java applications are typically compiled to Java bytecode, bytecode that can run on any Java virtual machine (JVM) regardless of the underlying computer architecture. The syntax (programming languages), syntax of Java is similar to C (programming language), C and C++, but has fewer low-level programming language, low-level facilities than either of them. The Java runtime provides dynamic capabilities (such as Reflective programming, reflection and runtime code modification) that are typically not available in traditional compiled languages.
