SOAP, an XML-based protocol, may be used for servers to communicate within this architecture.

Middleware is especially integral to modern information technology based on XML, SOAP, Web services, and service-oriented architecture.

An architecture based on REST can use WSDL to describe SOAP messaging over HTTP, can be implemented as an abstraction purely on top of SOAP ( e. g., WS-Transfer ), or can be created without using SOAP at all.

It is a distributed, open architecture protocol based on established standards such as the Internet Protocol Suite ( TCP / IP ), HTTP, XML, and SOAP.

In a service-oriented architecture, Simple Object Access Protocol or SOAP messages constructed with Extensible Markup Language ( XML ) messages can be used by consumer applications to cause web servers to create sessions.

Imagine your complicated Enterprise software system consisting of various pieces of software, developed over a period of tens of years-EJBs, legacy apps accessed using Java's connector architecture, SOAP services hosted on external servers, old code accessed through messaging middleware.

WSIF is an API for invoking WSDL-described services, whether they happen to be SOAP services or not ( for example, WSIF defines WSDL bindings so that EJBs, enterprise software accessible using JMS or the Java Connector architecture as well as local Java classes can all be described as first-class WSDL services and then invoked using the same, protocol-independent WSIF API ).

The SOAP specification defines the messaging framework which consists of:

It consists of a Java and a C ++ implementation of the SOAP server, and various utilities and APIs for generating and deploying Web service applications.

Furthermore, several independent " Seal-of-approval " ( SOAP ) agencies were envisioned which would rate Interpedia articles based on criteria of their own choosing ; users could then decide which agencies ' recommendations to follow.

OGSA is based on several other Web service technologies, notably WSDL and SOAP, but it aims to be largely agnostic in relation to the transport-level handling of data.

* The merging of several XML schemata like SOAP, SAML, XML ENC, XML SIG might cause dependencies on different versions of library functions like canonicalization and parsing, which are difficult to manage in an application server.

Since WSIF mirrors WSDL very closely, it also views SOAP as just one of several ways you might wish to expose your software's functionality.

The Global XML Web Services Architecture ( GXA ) was an announcement by Microsoft in 2002 of several proposals for extensions to SOAP.

CICS supports a number of industry standard and specifications including SOAP Version 1. 1 and Version 1. 2, Web services distributed transactions ( WS-Atomic Transaction ) and XML Encryption and Signing.

The WS-I Basic Profile ( official abbreviation is BP ), a specification from the Web Services Interoperability industry consortium ( WS-I ), provides interoperability guidance for core Web Services specifications such as SOAP, WSDL, and UDDI.

As a result it has a robust SOA that is more vetted than the current SOAP specifications but does not use the SOAP or WS standards.

People now frequently hold up REST as an approach to developing Web services, as an alternative to other distributed-computing specifications such as SOAP.

Three passes were required to translate source code to the " IT " language, then to compile the IT statements into SOAP assembly language, and finally to produce the object program, which could then be loaded into the machine to run the program ( using punched cards for data input, and outputting results onto punched cards ).

* SOAP ( Symbolic Optimal Assembly Program ) ( 1957 ) an assembly language for the IBM 650 computer

SOAP, originally defined as Simple Object Access Protocol, is a protocol specification for exchanging structured information in the implementation of Web Services in computer networks.

SOAP has three major characteristics: Extensibility ( security and WS-routing are among the extensions under development ), Neutrality ( SOAP can be used over any transport protocol such as HTTP, SMTP, TCP, or JMS ) and Independence ( SOAP allows for any programming model ).

As an example of how SOAP procedures can be used, a SOAP message could be sent to a web site that has web services enabled, such as a real-estate price database, with the parameters needed for a search.

SOAP was designed as an object-access protocol in 1998 by Dave Winer, Don Box, Bob Atkinson, and Mohsen Al-Ghosein for Microsoft, where Atkinson and Al-Ghosein were working at the time.

SOAP originally stood for ' Simple Object Access Protocol ' but this acronym was dropped with Version 1. 2 of the standard.

* The SOAP processing model defining the rules for processing a SOAP message

* The SOAP underlying protocol binding framework describing the rules for defining a binding to an underlying protocol that can be used for exchanging SOAP messages between SOAP nodes

It is responsible for processing the contents of the SOAP body and any SOAP header blocks targeted at it.

In some circumstances, a SOAP message might not reach an ultimate SOAP receiver, for example because of a problem at a SOAP intermediary.

An ultimate SOAP receiver cannot also be a SOAP intermediary for the same SOAP message.

* The SOAP message construct defining the structure of a SOAP message

The SOAP processing model describes a distributed processing model, its participants, the SOAP nodes, and how a SOAP receiver processes a SOAP message.

A SOAP node that transmits a SOAP message.

A SOAP node that accepts a SOAP message.

* SOAP message path

The set of SOAP nodes through which a single SOAP message passes.

The SOAP sender that originates a SOAP message at the starting point of a SOAP message path.

* Because of the verbose XML format, SOAP can be considerably slower than competing middleware technologies such as CORBA or ICE.

There are also concerns about performance due to Web services ' use of XML as a message format and SOAP / HTTP in enveloping and transporting.

* Create SOAP Message in Java

Adapters can be specific to an application ( e. g., built against the application vendor's client libraries ) or specific to a class of applications ( e. g., can interact with any application through a standard communication protocol, such as SOAP, SMTP or Action Message Format ( AMF )).

By December 2003, DIME had lost out, in competition with Message Transmission Optimization Mechanism and SOAP with Attachments ,.< ref >

WCF includes predefined bindings for most common communication protocols such as SOAP over HTTP, SOAP over TCP, and SOAP over Message Queues, etc.

The term " Message Exchange Pattern " has a specific meaning within the SOAP protocol.
