Summary of some technologies related to Web Services

1. After the weblogic samples program runs, you can see the program running status, soap generation, and server soap generation.
2. when using web services in a workshop, you can see the code, and after running the sample, you can see the relationship between the data process and process. For web services, it is still an open framework, if you want to use web services, you need to use relevant development tools. These development tools seem to have been bound to the platform, and the deployment methods for different platforms are different:
Weblogic ---- workshop
IBM webbench ---- webbench integetion
Tomcat-jboss (axis) --- apache (tools such as ant can be used)
The generated webservices files are different from those on other platforms. However, the appearance of the web layer is the same as the generation and support of the soap protocol.
The soap program on the client (which may require rpc) is located in the Directory D: eaweblogic81samplesserverexamplessrcexampleswebservicescomplexstatelessSession.
The implemented server program is under the Directory D: eaweblogic81samplesworkshopSamplesAppWebServices.
By combining the two programs, it becomes the entire service platform in the server background (the specific mechanism is implemented by the server and configuration file in the sample (in weblogic81 ).
3. WSDD is used to deploy the web sevices program. the wsdd file is configured to call the web services program. In fact, web serivces is a bit like struts. The web service program is actually a JavaBean, and then the access interface and access method are described through the service configuration file, at the underlying layer, Servlet is used to accept http messages, and different types of requests are forwarded to different JavaBean. This is achieved by the underlying program based on the configuration file.
4. the wsdl file only describes the service interfaces and types of web services. through it, you can know the access methods and communication methods .. Wsdl is a protocol used to describe services and provide customer access services.
5. wsif technology can obtain the access interface through parsing the wsdl file, but the obtained interface needs to be further confirmed. You can find the service through UDDI and define the access method by yourself. The best way is to generate client access programs based on the wsdl file.
