What is Universal Description, Discovery, and Integration (UDDI) in Web Services
Technology & Science / March 5, 2018

Universal Description, Discovery and Integration (UDDI) protocol is one of the major building blocks required for successful Web services. UDDI creates a standard interoperable platform that enables companies and applications to quickly, easily, and dynamically find and use Web services over the Internet (or Intranet). UDDI is a technology for publishing, querying, finding, and invoking Web services using a registry that provides data, metadata, and pointers to these services. Overview Universal Description Discovery and Integration (UDDI) is a standard sponsored by OASIS (Organization for the Advancement of Structured Information Standards). Often described as the yellow pages of Web services, UDDI is a specification for creating an XML-based registry that lists information about businesses and the Web services they offer. UDDI provides businesses a uniform way of listing their services and discovering services offered by other organizations. Though implementations vary, UDDI often describes services using WSDL and communicates via SOAP messaging. Registering a Web service in a UDDI registry is an optional step, and UDDI registries can be public or private (i.e. isolated behind a corporate firewall). To search for a Web service, a developer can query a UDDI registry to obtain the WSDL for the service he/she wishes to utilize….

What is Simple Object Access Protocol in Web Services
Technology & Science / February 27, 2018

Simple Object Access Protocol (SOAP) is the messaging protocol for web services. It is used to encode the information in the request and response messages. A SOAP message is operating system independent and it is a way for one program to communicate with other programs independently to the operating systems of the other programs. The SOAP messaging framework consists of four parts, the SOAP processing model, the SOAP extensibility model, the SOAP protocol binding framework, and the SOAP message construct. The processing model defines “the rules for processing a SOAP message”. Overview of┬áSimple Object Access Protocol SOAP supports different styles of information exchanged. It supports a Remote Procedure Call (RPC) style, which allows a request- response processing. And it also supports message oriented information exchange. This is good if you like to exchange business documents or other types of documents where the sender may not expect to get a response immediately. SOAP also have the following features: Protocol independence Language independence Platform and operating system independence Simple and extensible SOAP is an XML-based protocol from the W3C for exchanging data over HTTP. It provides a simple, standards-based method for sending XML messages between applications. Web services use SOAP to send…
