Apache Axis2
Apache Axis2 is a web service engine. It is a complete redesign and re-write of the widely used Apache Axis SOAP stack. Implementations of Axis2 are available in Java and C. Axis2 provides the capability to add Web services interfaces to Web applications. It can also function as a standalone application server. Why Apache Axis2 A new architecture for Axis2 was introduced during the August 2004 Axis2 Summit in Colombo, Sri Lanka. Some concepts from Axis 1.x, like handlers etc., have been preserved in the new architecture. Apache Axis2 supports SOAP 1.1 and SOAP 1.2, and it has integrated support for the REST style of Web services. The same business-logic implementation can offer both a WS-* style interface as well as a REST/POX style interface simultaneously. Axis2/Java has support for Spring Framework. Axis2/C is a high-performance Web services implementation. It has been implemented with portability and ability to be embedded or hosted in Apache Httpd, Microsoft IIS or Ax ...

Apache Axis2 Logo
The Apache () are a group of culturally related Native American tribes in the Southwestern United States, which include the Chiricahua, Jicarilla, Lipan, Mescalero, Mimbreño, Ndendahe (Bedonkohe or Mogollon and Nednhi or Carrizaleño and Janero), Salinero, Plains (Kataka or Semat or "Kiowa-Apache") and Western Apache ( Aravaipa, Pinaleño, Coyotero, Tonto). Distant cousins of the Apache are the Navajo, with whom they share the Southern Athabaskan languages. There are Apache communities in Oklahoma and Texas, and reservations in Arizona and New Mexico. Apache people have moved throughout the United States and elsewhere, including urban centers. The Apache Nations are politically autonomous, speak several different languages, and have distinct cultures. Historically, the Apache homelands have consisted of high mountains, sheltered and watered valleys, deep canyons, deserts, and the southern Great Plains, including areas in what is now Eastern Arizona, Northern Mexico (Sono ...

WS-Coordination
WS-Coordination is a Web Services specification developed by BEA Systems, IBM, and Microsoft and accepted bOASIS Web Services Transaction TCin it It describes an extensible framework for providing protocols that coordinate the actions of distributed applications. Such coordination protocols are used to support a number of applications, including those that need to reach consistent agreement on the outcome of distributed transactions. The framework defined in this specification enables an application service to create a context needed to propagate an activity to other services and to register for coordination protocols. The framework enables existing transaction processing, workflow, and other systems for coordination to hide their proprietary protocols and to operate in a heterogeneous environment. Additionally WS-Coordination describes a definition of the structure of context and the requirements for propagating context between cooperating services. However, this specificatio ...

Quality Of Service
Quality of service (QoS) is the description or measurement of the overall performance of a service, such as a telephony or computer network, or a cloud computing service, particularly the performance seen by the users of the network. To quantitatively measure quality of service, several related aspects of the network service are often considered, such as packet loss, bit rate, throughput, transmission delay, availability, jitter, etc. In the field of computer networking and other packet-switched telecommunication networks, quality of service refers to traffic prioritization and resource reservation control mechanisms rather than the achieved service quality. Quality of service is the ability to provide different priorities to different applications, users, or data flows, or to guarantee a certain level of performance to a data flow. Quality of service is particularly important for the transport of traffic with special requirements. In particular, developers have introduced Voice ...

Message-oriented Middleware
Message-oriented middleware (MOM) is software or hardware infrastructure supporting sending and receiving messages between distributed systems. MOM allows application modules to be distributed over heterogeneous platforms and reduces the complexity of developing applications that span multiple operating systems and network protocols. The middleware creates a distributed communications layer that insulates the application developer from the details of the various operating systems and network interfaces. APIs that extend across diverse platforms and networks are typically provided by MOM. This middleware layer allows software components (applications, Enterprise JavaBeans, servlets, and other components) that have been developed independently and that run on different networked platforms to interact with one another. Applications distributed on different network nodes use the application interface to communicate. In addition, by providing an administrative interface, this new, vir ...

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 similar to that of 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 endpoints, or ports. The WSDL specification provides an XML format for documents for this purpose. The abstract definitions of ports and messages are separated from their concrete use or instance, allowing the reuse of these ...

StAX
Streaming API for XML (StAX) is an application programming interface (API) to read and write XML documents, originating from the Java programming language community. Traditionally, XML APIs are either: * DOM based - the entire document is read into memory as a tree structure for random access by the calling application * event based - the application registers to receive events as entities are encountered within the source document. Both have advantages: DOM, for example, allows for random access to the document, and event driven algorithm like SAX has a small memory footprint and is typically much faster. These two access metaphors can be thought of as polar opposites. A tree based API allows unlimited, random access and manipulation, while an event based API is a 'one shot' pass through the source document. StAX was designed as a median between these two opposites. In the StAX metaphor, the programmatic entry point is a cursor that represents a point within the document. The ...

WS-Addressing
Web Services Addressing (WS-Addressing) is a specification of transport-neutral mechanism that allows web services to communicate addressing information. It essentially consists of two parts: a structure for communicating a reference to a Web service endpoint, and a set of message addressing properties which associate addressing information with a particular message. Description WS-Addressing is a standardized way of including message routing data within SOAP headers. Instead of relying on network-level transport to convey routing information, a message utilizing WS-Addressing may contain its own dispatch metadata in a standardized SOAP header. The network-level transport is only responsible for delivering that message to a dispatcher capable of reading the WS-Addressing metadata. Once that message arrives at the dispatcher specified in the URI, the job of the network-level transport is done. WS-Addressing supports the use of asynchronous interactions by specifying a common SOA ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SAML 2
Security Assertion Markup Language (SAML, pronounced ''SAM-el'', ) is an open standard for exchanging authentication and authorization data between parties, in particular, between an identity provider and a service provider. SAML is an XML-based markup language for security assertions (statements that service providers use to make access-control decisions). SAML is also: * A set of XML-based protocol messages * A set of protocol message bindings * A set of profiles (utilizing all of the above) An important use case that SAML addresses is web-browser single sign-on (SSO). Single sign-on is relatively easy to accomplish within a security domain (using cookies, for example) but extending SSO across security domains is more difficult and resulted in the proliferation of non-interoperable proprietary technologies. The SAML Web Browser SSO profile was specified and standardized to promote interoperability.J. Hughes et al. ''Profiles for the OASIS Security Assertion Markup Language ...

WS-SecureConversation
WS-SecureConversation is a Web Services specification, created by IBM and others, that works in conjunction with WS-Security, WS-Trust and WS-Policy to allow the creation and sharing of security contexts. Extending the use cases of WS-Security, the purpose of WS-SecureConversation is to establish security contexts for multiple SOAP message exchanges, reducing the overhead of key establishment. Features * Establish a new security context in following modes: ** Security context token created by a security token service (WS-Trust STS) ** Security context token created by one of the communicating parties and propagated with a message ** Security context token created through negotiation/exchanges * Renew security context * Amend Security context (add claims) * Cancel security context * Derive key: parties may use different keys per side and function (sign/encrypt), and change keys frequently to prevent cryptographic attacks * Maintain high secure context WS-SecureConversation is m ...

WS-Trust
WS-Trust is a WS-* specification and OASIS standard that provides extensions to WS-Security, specifically dealing with the issuing, renewing, and validating of security tokens, as well as with ways to establish, assess the presence of, and broker trust relationships between participants in a secure message exchange. The WS-Trust specification was authored by representatives of a number of companies, and waapproved by OASISas a standard in March 2007. Using the extensions defined in WS-Trust, applications can engage in secure communication designed to work within the Web services framework. Overview WS-Trust defines a number of new elements, concepts and artifacts in support of that goal, including: * the concept of a Security Token Service (STS) - a web service that issues security tokens as defined in the WS-Security specification. * the formats of the messages used to request security tokens and the responses to those messages. * mechanisms for key exchange WS-Trust is ...

WS-Security
Web Services Security (WS-Security, WSS) is an extension to SOAP to apply security to Web services. It is a member of the Web service specifications and was published by OASIS. The protocol specifies how integrity and confidentiality can be enforced on messages and allows the communication of various security token formats, such as Security Assertion Markup Language (SAML), Kerberos, and X.509. Its main focus is the use of XML Signature and XML Encryption to provide end-to-end security. Features WS-Security describes three main mechanisms: * How to sign SOAP messages to assure integrity. Signed messages also provide non-repudiation. * How to encrypt SOAP messages to assure confidentiality. * How to attach security tokens to ascertain the sender's identity. The specification allows a variety of signature formats, encryption algorithms and multiple trust domains, and is open to various security token models, such as: * X.509 certificates, * Kerberos tickets, * User ID/Password cr ...
