java.net.BindException: Address already in use

[tarkeshwar . prasad]

Hi ,
I have integrated the FTPServer in my application. FTP server is running 
fine in my application.  The FTPClient 
(org.apache.commons.net.ftp.FTPClient) connects to FTPServer on port 
18021. I am able to retrieve a file from the FTPServer.   Whenever I try 
to retrieve more than one files from the FTPServer.  Then I am getting 
exception "BindException: Address already in use" . 
Could you please tell me How I can resolve this problem?  Please let me 
know if you have any solutions or suggestion for this. I am looking 
forward your response.

I am also sending code snippets:

FTPClient client = new FTPClient();
        System.out.println("Connecting FTP Server");
        client.connect("10.150.1.111",18021);
        //client.connect("10.150.1.111");
        System.out.println("FTP Server Connected");
 
        int reply = client.getReplyCode();
        System.out.println("[EmbeddedFtpSessionPolicy] FTP connection 
reply code is "+reply);
        if (FTPReply.isPositiveCompletion(reply)) {
                System.out.println("[EmbeddedFtpSessionPolicy] connection 
established to "+client.getRemoteAddress().getHostAddress()); 
                boolean success = client.login("admin", "admin");
                System.out.println("FTP Server success "+success);
        }
        File local1 = new File("TEST.log");
        File local = new File("ftpd.log");
        boolean  status;
        // if we comment any one of the given bellow  it will work 
properly ....
        status = client.retrieveFile("/sdp/database/ftpd.properties", new 
FileOutputStream(local));
        status = client.retrieveFile("/sdp/database/TEST.log", new 
FileOutputStream(local1));

        if (client.isConnected()) {
                System.out.println("FTP Server disconnected");
                client.logout();
                client.disconnect();
                client =null;
        }
        System.out.println("FTP Server disconnected ");
