Hi ranchers,

Iam using apache commons FTPClient (In "commons-net-1.4.1.jar" ). Iam using it to read files and write a file onto a FTP server.

This class works fine in Windows environment, but its not working on linux ( red hat linux) environment. The following snippet code is for reading a file on FTP. This piece of code results to deadlock situation at bolded code.



FTPClient ftpclient = new FTPClient();
ByteArrayOutputStream baos = null;
ByteArrayInputStream bais = null;
try {
ftpclient.connect(ftpLocation.trim());
// check reply code.
if (!FTPReply.isPositiveCompletion(ftpclient.getReplyCode())) {
ftpclient.disconnect();
;
return null;
} else {
System.out.println("IN Positive Connection made; Reply code = "
+ ftpclient.getReplyCode());
}

ftpclient.login(ftpUserId.trim(), ftpPwd.trim());
ftpclient.changeWorkingDirectory(strConfigDirectory.trim());

baos = new ByteArrayOutputStream();
ftpclient.retrieveFile(strConfigFileName.trim(), baos);
bais = new ByteArrayInputStream(baos.toByteArray());

ftpclient.logout();
ftpclient.disconnect();
} catch (IOException e) {
e.getMessage();
} catch (Exception e) {
e.getMessage();
}

How do you know it's deadlocked? What else is going on that it could deadlock with?

It may not make a difference here, but I'd advise always to check the return values of methods such as login, changeWorkingDirectory and the other ones.
