Setting connect timeout for FtpClient

Though there is possible solution for that older version of Commons Net library, I suggest to figure out why wrong version of Commons Net is used. To do this you may include following code to the place where FTPClient is used in your webapp:

FTPClient ftpClient = ...;
if(ftpClient.getClass().getClassLoader() instanceof java.net.URLClassLoader) {
    URL[] urls = ((java.net.URLClassLoader) ftpClient.getClass().getClassLoader()).getURLs();
    // log these urls somewhere and check - these are urls from where your FTPClient may be loaded from
}

In case if FTPClient is loaded not by java.net.URLClassLoader then it may get more complicated to check the classpath, though it should not be a problem.

Hope this helps...

It must be in the way your calling the setConnectTimeout, because it does exist. setConnectTimeout is not a static call, you must call it after you allocate the FTPClient object and do the set prior to the connect.

FTPClient ftp = new FTPClient();
ftp.setConnectTimeout(5000); // 5000 Milliseconds (5 Seconds)
... 
ftp.connect(server, port); 

    FTPClient ftp = new FTPClient();

    ftp.setDefaultTimeout();
    ftp.setDataTimeout();
    ftp.setConnectTimeout();
    ftp.setSoTimeout();
    ftp.setControlKeepAliveTimeout();
    ftp.setControlKeepAliveReplyTimeout();

From Apache docs:

   /**

     * This value is only used previous to a call to
     * {@link #connect connect()}
     * and should not be confused with {@link #setSoTimeout setSoTimeout()}
     * which operates on an the currently opened socket.  _timeout_ contains
     * the new timeout value.
