EmployeeServiceConsumer

Consumer Steps:
--------------

1.Get the wsdl file from the Provider.
2.Test the service through SOAP UI.
3.Generate the artifacts.
C:>wsimport -d src -keep -verbose wsdl location
output: artifacts.
  1.Service class.
  2.Interface name
  3.request and response classes
  4.endpoint url.

4.Write webservice client code.

  1.create service class object
  2.call the port and it returns interface
  3.prepare the webservice request.
  4.call the getOrder API.
  5.call the getPrice API.



Step to develop client in eclipse.
1.Create java project.

2. create lib folder. copy all the jars(jaxws) in to lib folder.

3.generate artifacts using wsdl.
Goto Command prompt execute fillowing commnad

  E:\WorkSpace\webservice\JaxWsConsumer>wsimport -d src -keep -verbose http://localhost:2020/JaxWsOrderServiceProvider/online?wsdl

4. Write client application  code in main method based class.
   Steps to write logic in client class.

    1.create service class object
2.call the port and it returns interface
3.prepare the webservice request.
4.call the getOrder API.
5.call the getPrice API.




Sample example for SAOP using Apache CXF and Spring Boot.

cxf spring boot dependency
    cxf-spring-boot-starter-jars
application.properties
  cxf.jars.component-scan=true
  server.context-path=/helloapp

Steps:
1.Create maven project
2.Create End point class(service)
3.Create configuation class.
4.Test the application
