FTP Sync Upload Tree w/ Must-Match Filename Constraints

See more FTP Examples

Demonstrates how synchronize a directory tree in the upload direction, but only upload files matching a set of wildcard filenames.

Note: This example requires Chilkat v9.5.0.76 or greater.

Java

import com.chilkatsoft.*;

public class ChilkatExample {

  static {
    try {
        System.loadLibrary("chilkat");
    } catch (UnsatisfiedLinkError e) {
      System.err.println("Native code library failed to load.\n" + e);
      System.exit(1);
    }
  }

  public static void main(String argv[])
  {
    boolean success = false;

    // This example requires the Chilkat API to have been previously unlocked.
    // See Global Unlock Sample for sample code.

    CkFtp2 ftp = new CkFtp2();

    ftp.put_Hostname("ftp.something.com");
    ftp.put_Username("my_login");
    ftp.put_Password("my_password");

    // Connect and login to the FTP server.
    success = ftp.Connect();
    if (success != true) {
        System.out.println(ftp.lastErrorText());
        return;
        }

    // Set the current remote directory to the root of
    // the tree to receive the uploaded files.
    success = ftp.ChangeRemoteDir("/subDir1");
    if (success != true) {
        System.out.println(ftp.lastErrorText());
        return;
        }

    // Possible synchronization modes are:
    // mode=0: Upload all files
    // mode=1: Upload all files that do not exist on the FTP server.
    // mode=2: Upload newer or non-existant files.
    // mode=3: Upload only newer files. If a file does not already exist on the FTP server, it is not uploaded.
    // mode=4: transfer missing files or files with size differences.
    // mode=5: same as mode 4, but also newer files. 

    // This example will upload all files, but only those files having filenames
    // that match *.gif and *.eml

    // Imagine our local directory tree has these files and directories:

    // 	accentedLatin1.txt
    // 	accentedUtf8.txt
    // 	alice.key
    // 	anter_cert.pem
    // 	chiliPepper.gif
    // 	helloWorld.pdf
    // 	abc/chiliPepper.gif
    // 	abc/ghk/
    // 	data/chiliPepper.gif
    // 	data/xyz/dkimHtmlBody.txt
    // 	data/xyz/dkimVerifyTest.eml
    // 	data/xyz/emailForCreateDsn.eml
    // 	text/frenchUtf8.txt
    // 	text/helloWorld.txt
    // 	text/PolishEmailBody.txt
    // 	text/something/

    ftp.put_SyncMustMatch("*.eml; *.gif");
    int mode = 0;
    success = ftp.SyncRemoteTree("c:/temp/subDir1",mode);
    if (success != true) {
        System.out.println(ftp.lastErrorText());
        return;
        }

    success = ftp.Disconnect();

    // Show the files downloaded.
    CkStringTable st = new CkStringTable();
    ftp.GetSyncedFiles(st);

    int numFiles = st.get_Count();
    int i = 0;
    String remoteFilename;
    while (i < numFiles) {
        System.out.println(st.stringAt(i));
        i = i+1;
        }

    // Output showing the files uploaded:

    // chiliPepper.gif
    // abc/chiliPepper.gif
    // data/chiliPepper.gif
    // data/xyz/dkimVerifyTest.eml
    // data/xyz/emailForCreateDsn.eml
