FTP file transfer in Java using Apache Commons Net

The following sample code works well with Java 1.5 and Apache Commons Net 1.4.1

import org.apache.commons.net.ftp.*;
...
boolean ftpTransfer(String localfile, String destinationfile)
{
	String server = "ftp.domain.com";
	String username = "ftpuser";
	String password = "ftppass";
	try
	{
		FTPClient ftp = new FTPClient();
		ftp.connect(server);
		if(!ftp.login(username, password))
		{
			ftp.logout();
			return false;
		}
		int reply = ftp.getReplyCode();
		if (!FTPReply.isPositiveCompletion(reply))
		{
			ftp.disconnect();
			return false;
		}
		InputStream in = new FileInputStream(localfile);
		ftp.setFileType(ftp.BINARY_FILE_TYPE);
		boolean Store = ftp.storeFile(destinationfile, in);
		in.close();
		ftp.logout();
		ftp.disconnect();
	}
	catch (Exception ex)
	{
		ex.printStackTrace();
		return false;
	}
	return true;
}
