File Upload in Jersey Restful service

About:

There are many blogs which discuss on how to do file transfer in JAX-RS /Restful service all this blogs discuss using the Multipartformdata i.e. FormDataParam as the input Stream.
In this Blog, I will  be discussing on one of the way about how to create a service which will accept the File Object as input for the method which it consumes in the form XML.


Code: 

Bean Class

package model;
import java.io.InputStream;
import javax.activation.DataHandler;
import javax.xml.bind.annotation.XmlRootElement;

@XmlRootElement
public class FileData {
    public FileData() {
        super();
    }
    
    String fileName;
    byte[] fileInfo;


    public void setFileName(String fileName) {
        this.fileName = fileName;
    }

    public String getFileName() {
        return fileName;
    }


    public void setFileInfo(byte[] fileInfo) {
        this.fileInfo = fileInfo;
    }

    public byte[] getFileInfo() {
        return fileInfo;
    }

}

Service Class

package model;


import java.io.ByteArrayInputStream;
import java.io.InputStream;
import java.io.OutputStream;
import java.io.FileOutputStream;

import javax.ws.rs.Consumes;
import javax.ws.rs.POST;
import javax.ws.rs.Path;

@Path("model")
public class FileService {
    public FileService() {
        super();
    }


    @POST
    @Consumes("application/xml")
    public void uploadFile(FileData fd) {
        try {
            OutputStream os = new FileOutputStream("" + fd.getFileName());
            InputStream is = new ByteArrayInputStream(fd.getFileInfo());
             
            byte[] buffer = new byte[1024];
            int bytesRead;
            //read from is to buffer
            while ((bytesRead = is.read(buffer)) != -1) {
                os.write(buffer, 0, bytesRead);
            }
            is.close();
            //flush OutputStream to write any buffered data to file
            os.flush();
            os.close();


        } catch (Exception e) {
            System.out.println("Inside the Service"+e);
        }

    }

}

For Client :

I will explain in another blog on how to consume this in REST DataControl / URL DataControl
