Lets walk through the java code now, here we basically define the interfaces for our web services and add the implementation for the same as well

• The HelloWorld.java interface has a one method that takes in a string parameter. Notice the annotations (@WebService to define a web service and @WebParam to define a parameter)

  package com.yosanai.tutorial.ws.hellowebservice;
  
  import javax.jws.WebParam;
  import javax.jws.WebService;
  
  /**
   * @author Saravana P Shanmugam
   * 
   */
  @WebService
  public interface HelloWorld {
      String sayHi(@WebParam(name = "message") String text);
  }
  

• The FileManagement.java interface has a one method that takes in a File.java object as parameter. Notice the annotations (@WebService to define a web service and @WebParam to define a parameter)

  package com.yosanai.tutorial.ws.hellowebservice;
  
  import javax.jws.WebParam;
  import javax.jws.WebService;
  
  /**
   * @author Saravana P Shanmugam
   * 
   */
  @WebService
  public interface FileManagement {
  
      public String upload(@WebParam(name = "file") File file) throws Exception;
  }
