Web service Standards
Web service development is based on standards that include some technology. The main is soap,wsdl (Web

services are transparent to them, even when the implementation platform of Web Services is migrated from J2EE. NET or the opposite migration process, users can have no idea about this. For a loose pot, especially for Web Services in the Internet environment, a message excha
The primary challenge for testing the effectiveness, performance, scalability, reliability, and security of Web Services is the distribution of Web services.
To enable complete Web services to achieve the desired functionality, c

Web services are often described from the perspective of its component technology. SOAP, UDDI, WSDL, XML, and HTTP each form part of the Web services system, and they all play an important role. Let's look at the contribution of XML technology to the
standard way to represent these software assets and interact with them; now the focus has shifted to the assembly of applications based on these artifacts.
While the service-oriented Architecture (SOA) for business applications is discussed here, service-oriented Architecture (SOA) can also be used for other distributed systems, such as grid computing and advanced Web services specifications (for example,

capabilities WebService is to provide collaborative capabilities for different application systems on different platforms. In order to make a company's network application achieve the highest efficiency, it should be able to achieve seamless interaction with its partners, suppliers and WebServices between customers. If interactions cannot be easily implemented between many WebServices, the efficiency of the application will be greatly reduced. However, in reality, this situation is very likely
