references used :

server code & client call

server function name

/*** SERVER SIDE CODE****/

 @POST
 @Path("/upload/{attachmentName}")
 @Consumes(MediaType.APPLICATION_OCTET_STREAM)
    public void uploadAttachment(
            @PathParam("attachmentName") String attachmentName, 
            @FormParam("input") InputStream attachmentInputStream) {               
    InputStream content = request.getInputStream();

// do something better than this
OutputStream out = new FileOutputStream("content.txt");
byte[] buffer = new byte[1024];
int len;
while ((len = in.read(buffer)) != -1) {
    // whatever processing you want here
    out.write(buffer, 0, len);
}
 out.close();

 return Response.status(201).build();
}


      /**********************************************/


 /** 
   CLIENT SIDE CODE
 **/
    // .....
  client.setChunkedEncodingSize(1024);
  WebResource rootResource = client.resource("your-server-base-url");
    File file = new File("your-file-path");
   InputStream fileInStream = new FileInputStream(file);
    String contentDisposition = "attachment; filename=\"" + file.getName() + "\"";
    ClientResponse response = rootResource.path("attachment").path("upload").path("your-file-name")
          .type(MediaType.APPLICATION_OCTET_STREAM).header("Content-Disposition", contentDisposition)
         .post(ClientResponse.class, fileInStream);

You should split the file in the client and restore part of the file in the server. and after that you should merge the files together. Take a look at split /merge file on coderanch

Enjoy ! :)
