Web Service

1. Definition:

Web Service is a platform-independent, low-coupling, self-contained, programmable Web-based application that uses Open XML (a subset of standard common markup languages) to describe, publish, discover, orchestrate, and configure these applications for the development of distributed, interoperable applications.

2.WEB Service technology enables different applications running on different machines to Exchange data or integrate with each other without the use of additional, specialized third-party software or hardware.

Soap: Simple Object access Protocol protocol. is the communication protocol for XML WEB Service. When a user finds your WSDL description document through UDDI, he can invoke one or more of the actions in the Web service that you set up by soap. SOAP is a specification for calling methods in the form of XML documents that can support different underlying interfaces, such as HTTP (S) or SMTP.

wsdl: (Web Services Description Language) A WSDL file is an XML document that describes a set of SOAP messages and how to exchange them. In most cases, it is automatically generated and used by the software.

UDDI (Universal Description, Discovery, and integration) is a new project that focuses on Web service providers and users. Before a user can invoke a Web service, it is important to determine which business methods are included in the service, to find the called interface definition, and to prepare the software on the server side, and UDDI is a mechanism to guide the system through the description document to find the appropriate service. UDDI uses the SOAP message mechanism (standard xml/http) to publish, edit, browse, and find registration information. It uses XML format to encapsulate various types of data and send it to the registry or to the registry to return the required data.

There are 3 ways to call WebService

1). HttpGet
2). HttpPost
3). HttpSoap

The advantage of soap is that it can pass structured data, while the first two do not.

Mode one (called directly on the Web page):

www.webxml.com.cn

Mode two (via MyEclipse connection webserver):

Way three (, to live locally these types of files are copied to the project you need to use, you can invoke the method provided by WebService as you would call a local class):

Error may occur: (Package name and existence path consistent, my resolved)

Workaround (, the following package name should be wrong to write cn.com.webxml)
