How to add Ftp transfer to my app???

Question

I need to upload htm files to my ftp server.
I'm new to java and I need to know if I need and API to add this capabilities to my app or if there is a class that can do this.
Do you know a link where I can get some ftp code samples?
Thank
Diego

J? napot, Laszlo.
I suspect the problems are much bigger than that.K?sz?n?m sz?pen, Ferenc -- the f is for Ferenc, isn't it? -- but just because we among the chosen who've done their dissertation on CLASSPATH doesn't mean we can't share out enlightenment.
Suggestions:
1. Download the right zip file: it's Commons Net, not Commons Upload.
2. Unzip it to find the file commons-net-1.1.0.jar.
3. There are many things you can do with this jar: put it on your CLASSPATH, refer to it using a command line argument etc... but perhaps the simplest way (assuming you're working on your own machine so there's no one to object to it): make it an extension: copy it into the appropriate jre/lib/ext directory . Where is this? It depends on your set up, but if you've installed the jdk, you should have a path like C:\j2sdk1.4.2etc...\jre\lib\ext and there's another copy of the jre in C:\Program Files\java\jre1.4.2etc...\lib\ext. You might as well copy the jar into both locations -- can't hurt.
4. Take a look at the docs you unzipped to find out the right inport statement and some sample code. For example, FTPClient's doc includes:
import org.apache.commons.net.ftp.*;
try {
      int reply;
      ftp.connect("ftp.foobar.com");
      System.out.println("Connected to " + server + ".");
      System.out.print(ftp.getReplyString());
      // After connection attempt, you should check the reply code to verify
      // success.
      reply = ftp.getReplyCode();
      if(!FTPReply.isPositiveCompletion(reply)) {
        ftp.disconnect();
        System.err.println("FTP server refused connection.");
        System.exit(1);
    } catch(IOException e) {
      if(ftp.isConnected()) {
        try {
          ftp.disconnect();
        } catch(IOException f) {
          // do nothing
      System.err.println("Could not connect to server.");
      e.printStackTrace();
      System.exit(1);
    }Viszontl�t�sra!
