Giving permission to a ftp FILE java

Question

i have a class in android that connect with the ftp, and store an image, that works perfect the problem is when i am trying to move the image to another directory( i use a php page to moderate that image) it doesnt have permission to handle it, i want to put the permission to 0777 but only the "java code" can do it but i dont know how,

I am using FTPClient library

this is my code

 File imageFile = new File(url[0]); 



         FTPClient ftpClient = new FTPClient();   ftpClient.connect(InetAddress.getByName("myserver"));
         ftpClient.login("login", "pass");

         ftpClient.changeWorkingDirectory("directory");
         ftpClient.setFileType(FTP.BINARY_FILE_TYPE);
         BufferedInputStream buffIn=null;
         buffIn=new BufferedInputStream(new FileInputStream(imageFile));
         ftpClient.enterLocalPassiveMode();
         ftpClient.storeFile(url[1]+".jpg", buffIn);
         buffIn.close();
         ftpClient.logout();
         ftpClient.disconnect();

Answer 1

I made it by command

 ftpClient.storeFile(url[1]+".jpg", buffIn);
         boolean a = ftpClient.sendSiteCommand("chmod " + "777 " + "/absolutepath/"+url[1]+".jpg");
