Problem with edtFTPj/PRO and Java 7 (Connection reset)

Question

Hello,

I think I have found a problem with edtFTPj/PRO and Java 7. The following test-code runs well under Java 6, but crash with Java 7:

<code>
ProFTPClient ftp = null;
Logger log = Logger.getLogger(CUtility.class);
Logger.setLevel(Level.ALL);

ftp = new ProFTPClient();
ftp.setRemoteHost(strHost);
ftp.connect();

FTPMessageCollector listener = new FTPMessageCollector();
ftp.setMessageListener(listener);

log.debug("Logging in");
ftp.login(strUser, strPass);

log.debug("Setting up passive");
ftp.setConnectMode(FTPConnectMode.PASV);

log.debug("ASCII transfers");
ftp.setType(FTPTransferType.ASCII);

log.debug("change Directory");
ftp.chdir(strPath);

// get directory and print it to console
log.debug("Directory (*.*):");

String[] files = ftp.dir("*.*", false);
for (int i = 0; i < files.length; i++)
{
log.debug(files[i]);
}

log.debug("Quitting client");
ftp.quit();
</code>


The command dir() throws the following exception:

We've resolved this problem. If you are on Windows it is the Windows firewall that is blocking Java 7 when it sees certain FTP commands being sent (PASV and PORT).

Normally, the Windows firewall prompts to add a newly installed program. But in this case it doesn't seem to happen - we aren't sure why.

To resolve the problem, go to Windows Firewall Settings, and in the Exceptions tab, choose "Add Program" to add java.exe by browsing to your installation of Java 7.
