Question

I tried working Ftp download stand alone application and it works fine. But when I included that into Quartz scheduler in web application, it stucks.

Here is what I did.

public class FtpTransfer implements StatefulJob {
public void execute(JobExecutionContext arg0) throws JobExecutionException {
    FTPClient ftp = new FTPClient();
    FileOutputStream br = null;
    try
    {
        ftp.connect("localhost");
        ftp.login("admin", "admin");
        String path = "alfresco/MYPUB/Admin/TMM/Pickup";
        ftp.setFileType(FTPClient.BINARY_FILE_TYPE);
        ftp.changeWorkingDirectory(path);
        System.out.println("After Changing Directory path");
        FTPFile[] ftpFile =  ftp.listFiles(path);
        System.out.println("After getting list of files");
        System.out.println("Length : "+ftpFile.length);
        System.out.println("----------------- Downloaded -------------");
        for(FTPFile tempFtpFiles : ftpFile) {
            br = new FileOutputStream("e:\\Downloaded\\"+tempFtpFiles.getName());
            ftp.retrieveFile(tempFtpFiles.getName(), br);
            System.out.println(tempFtpFiles.getName());
        }
        System.out.println("------------------------------------------");

    }
    catch(Exception exception) {
        System.out.println("Error : "+exception);
    } finally {
        try {
            if(br!=null){
                br.close();
            }
            ftp.disconnect();
        } catch(IOException e) {
            e.printStackTrace();
            System.out.println("Error : "+e);
        }
    }
}
}

When I start the server, It prints

After Changing Directory path
After Changing Directory path
After Changing Directory path

Every 10 secs. But It is not downloading the files from the path given. Mailnly the program didn’t crossed the line FTPFile[] ftpFile = http://ftp.listFiles(path). What did I do wrong?

Thanks for your comments. I have found the problem. After included jakarta-oro.jar in lib, its working fine.
