A summary of technical learning about Web services

Services|web 1. After the WebLogic's samples program runs, you can see how the program works and soap generation and the soap generation of the server.
2. When using Web services in workshop, you can see the code, and the relationship between the process and the process of the data after the sample is run, is still an open framework for Web services, if you want to use Web services, With the relevant development tools, these development tools seem to have been bundled with the platform, and different platforms are deployed differently:
WebLogic----Workshop
IBM webphere----Webphere integetion
Tomcat-jboss (axis)---apache (available using tools such as Ant)
Under different platforms, he generates webservices files that are not the same as other platforms. But the appearance of the Web layer is the same as the generation and support of the SOAP protocol
For the client's SOAP program (which may require RPC to implement) in: D:\bea\weblogic81\samples\server\examples\src\examples\webservices\complex\ The Statelesssession directory
And the implementation of the server's program in: D:\bea\weblogic81\samples\workshop\SamplesApp\WebServices directory
Combining the two programs becomes the entire service platform for the server backend (the specific mechanism is implemented through the server and configuration files (in weblogic81) of sample.)
3. For WSDD is used to deploy the Web Sevices program, it enables the server through the configuration of the. wsdd file, completes the call to the Web Services program, in fact the Web serivces a bit like Struts,web service program actually JavaBean, The service profile is then used to describe the access interface and access methods, which are implemented by using a servlet to accept HTTP messages, and then forwarded to different JavaBean by different types of requests, which are implemented by the underlying program according to the configuration file.
The 4.wsdl file is simply a description of the type of service interface and service for Web services through which customers can know how to access and how to communicate.. WSDL is a protocol that describes a service and provides a customer access service.
The 5.wsif technology can obtain the access interface by parsing the WSDL file, but the obtained interface needs further confirmation. You can find a service in UDDI and then define how you want to access it. The ideal way is to be able to generate client Access programs based on WSDL files.
