XFire is a lightweight Java SOAP framework that has been discontinued. However, you can use other modern SOAP frameworks like Apache CXF to achieve large file transfer functionality in Web Services.

The steps below outline how to implement large file transfer functionality in WebServie using Apache CXF.

  1. Add the dependency of Apache CXF to your project. You can either use Maven or manually import the JAR file.
  2. Create a Java interface to define your Web Service methods. For example, you could create an interface called FileTransferService and define a file upload method within it.
import javax.jws.WebMethod;
import javax.jws.WebService;
import javax.jws.soap.SOAPBinding;

@WebService
@SOAPBinding(style = SOAPBinding.Style.RPC)
public interface FileTransferService {

    @WebMethod
    String uploadFile(byte[] fileData);

}
  1. Implement the interface. Create a class named FileTransferServiceImpl that implements the FileTransferService interface and the file upload method.
@WebService(endpointInterface = "com.example.FileTransferService")
public class FileTransferServiceImpl implements FileTransferService {

    @Override
    public String uploadFile(byte[] fileData) {
        // 实现文件上传逻辑
        // ...
        return "File uploaded successfully";
    }

}
  1. Set up the server for CXF. Create a configuration file named cxf-servlet.xml to configure the server for CXF.
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:jaxws="http://cxf.apache.org/jaxws"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
           http://www.springframework.org/schema/beans/spring-beans.xsd
           http://cxf.apache.org/jaxws
           http://cxf.apache.org/schemas/jaxws.xsd">

    <jaxws:endpoint id="fileTransferService"
                    implementor="com.example.FileTransferServiceImpl"
                    address="/fileTransferService"/>

</beans>
  1. Configure the web.xml file of the web application to register the CXF servlet with the web container.
<servlet>
    <servlet-name>CXFServlet</servlet-name>
    <servlet-class>org.apache.cxf.transport.servlet.CXFServlet</servlet-class>
</servlet>

<servlet-mapping>
    <servlet-name>CXFServlet</servlet-name>
    <url-pattern>/services/*</url-pattern>
</servlet-mapping>
  1. Start the web application and test it. You can now test the file upload method by visiting http://localhost:8080/your-web-app/services/fileTransferService.

The above are the basic steps to implement large file transfers in Web Services using Apache CXF. Feel free to modify and expand based on your own needs.
