{{ProductTopic|RemObjects SDK|Architecture}} __NOTOC__ ==SOAP Message Overview== [[SOAP]] is a standardized [[XML]] based protocol for exchanging messages between client and server, and forms the foundation of [[Web Services]]. [[SOAP]] is widely used across the internet and implementations exist for virtually every conceivable platform, making [[SOAP]] messaging the ideal format for exposing your services to a wide variety of consumers, or accessing existing web services provided by others. Since [[SOAP]] is an open standard and not specific to [[RemObjects SDK]], it easily enables communication with non-[[RemObjects SDK]] systems. [[SOAP]] has disadvantages over the [[RemObjects SDK]]'s own [[BinMessage]] format in that it is based on [[XML]] and very verbose, adding a substantial overhead on the data with a message that is often larger than the actual data. The specification is also very ambiguous, resulting in potential differences and incompatibilities with the many [[SOAP]] implementations out there. [[SOAP]] also provides its own format for defining the structure of services, comparable to [[RemObjects SDK]]'s [[RODL]] files, so called [[WSDL]] (Web Service Definition Language). [[RemObjects SDK]] provides support for importing [[WSDL]] files from within [[Service Builder]] and the [[Delphi]] IDE, and allows clients to retrieve [[WSDL]] for services exposed via SOAP Message and [[HTTP]]. ==Use Cases== Due to its disadvantages over [[BinMessage]], you should generally use [[SOAP]] only to either communicate with existing Web Services that are provided by third parties, or to open your own services up to access by other third parties not using [[RemObjects SDK]]. In the latter case, you will most likely use [[Smart Services]] to expose your services as [[SOAP]] and [[BinMessage]] at the same time. ==Components== * {{class|SoapMessage}} ([[.NET]]) * {{class|TROSOAPMessage}} ([[Delphi]]) * {{class|ROSoapMessage}} ([[Xcode]]) ===Configuring the SOAP message=== See [[SOAP Message Options]] for the options on the soap message components. == See Also == * [[Messages]] ** [[BinMessage]] ** [[XML-RPC Message]] ** [[PostMessage]] * [[SOAP Mapping]] * [[SOAP Web Services]] * [http://www.w3.org/TR/soap/ W3C XML Protocol Working Group homepage] * [http://en.wikipedia.org/wiki/SOAP Simple Object Access Protocol on Wikipedia] {{RemObjects SDK}} [[category:text]] [[category:RemObjects SDK]] [[category:Architecture]]
