import org.apache.commons.fileupload.servlet.ServletFileUpload;

@Path("/upload")

public class RESTMultipleFileUpload {

    private static final String FILE_UPLOAD_PATH = "C:\\Users\\charan\\Documents\\webservice\\";
    //private static final String CANDIDATE_NAME = "candidateName";
    private static final String SUCCESS_RESPONSE = "Successful";
    private static final String FAILED_RESPONSE = "Failed";

    @POST
    @Consumes(MediaType.MULTIPART_FORM_DATA)
    @Produces("text/plain")
    @Path("/multipleFiles")
    public String registerWebService(@Context HttpServletRequest request)
    {
        String responseStatus = SUCCESS_RESPONSE;        
        String candidateName = null;
        System.out.println("first ");
        System.out.println("Two::"+request);
        //checks whether there is a file upload request or not
        if (ServletFileUpload.isMultipartContent(request))
        {
            final FileItemFactory factory = new DiskFileItemFactory();
            final ServletFileUpload fileUpload = new ServletFileUpload(factory);
            try
            {
                System.out.println("t ");
                /*
                 * parseRequest returns a list of FileItem
                 * but in old (pre-java5) style
                 */
                final List items = fileUpload.parseRequest(request);

                if (items != null)

                    while (iter.hasNext())
                    {
                        final FileItem item = (FileItem) iter.next();
                        final String itemName = item.getName();
                        final String fieldName = item.getFieldName(); 
                        final String fieldValue = item.getString();

                        if (item.isFormField())
                        {
                            candidateName = fieldValue;

                            System.out.println("Candidate Name: " + candidateName);
                        }
                        else
                        {
                                final File savedFile = new File(FILE_UPLOAD_PATH + File.separator
                                         + itemName);
                                System.out.println("Saving the file: " + savedFile.getName());
                                item.write(savedFile);                                
                        }

                    }
                }
            }
            catch (FileUploadException fue)
            {
                responseStatus = FAILED_RESPONSE;
                fue.printStackTrace();                
            }

                e.printStackTrace();
            }
        }        

        System.out.println("Returned Response Status: " + responseStatus);

        return responseStatus;
    }
