Java to Read a file through HTTP and write to FTP

Below is the code which will provide the following:

• Read a file through HTTP protocol
• Write the output to FTP on another location
• Implementation of FileOutputStream & FileInputStream
• Ready to use code

Below code demonstrates reading a file from URL using java URL

String Source="http://serverip/filepath/fax.pdf";

URL url = new URL(source);

URLConnection urlC = url.openConnection();

InputStream is = url.openStream();

Date date = new Date(urlC.getLastModified());

System.out.flush();

Below is the FTP connection code. (Pl refer to my other post for the implementation of properties file to store & retrieving FTP credentials)

//FTP conenction code                        

ResourceBundle myResources = new Resource_Properties().getBundle_Ftp();     

String ftphost=myResources.getString("ftp_host");

String ftpuser=myResources.getString("ftp_username");

String ftppassword=myResources.getString("ftp_pwd");

int ftpport=Integer.parseInt(myResources.getString("ftp_port"));

int ftpportread=Integer.parseInt(myResources.getString("ftp_portread"));

FTPClient ftp = new FTPClient();

ftp.connect(ftphost,ftpport);

ftp.login(ftpuser,ftppassword);

System.out.println("successfully connected");

Below is the code which will check whether the target folder exists or not. If not exists will create a new folder. Then it will write the file to FTP

URL u = new URL("http://"+ftphost+":"+ftpportread+""+targetlocation); 

HttpURLConnection huc =  (HttpURLConnection)  u.openConnection(); 

huc.setRequestMethod("GET");

huc.connect();

int rc = huc.getResponseCode();

if(rc==404)  

{

//targetlocationloc is the target folder in which we need to write the FTP o/p

ftp.makeDirectory(targetlocationloc);

}//if 

//targetfile is the o/p file 

String pathh= targetlocation+targetfile;

FileOutputStream  fos = null;

fos = new FileOutputStream((targetfile));

int oneChar;

while((oneChar = is.read()) != -1) 

{

fos.write(oneChar);

count++;

}

is.close();

fos.close();

File fullFile  = new File(targetfile);  

FileInputStream fis=new FileInputStream(fullFile);

ftptest ft=new ftptest(fis,pathh );

fullFile.delete();
