Getting a StringIndexOutOfBoundsException while putting file

Question

Hi ,
I am getting a StringIndexOutOfBoundsException while trying to upload a file onto a server.

Please find below the logs of the same. The line of code that throws the error is as follows


ftp.put(fileBase2.localCopy.getAbsolutePath(), s);


2009/08/12 02:47:47:385] ERROR -->> FTPSender -> FAILED to distribute file to FTP server java.lang.StringIndexOutOfBoundsException: String index out of range: -50 at java.lang.String.substring(String.java:1444) at com.enterprisedt.net.ftp.FTPControlSocket.getPASVParts(FTPControlSocket.java:838) at com.enterprisedt.net.ftp.FTPControlSocket.createDataSocketPASV(FTPControlSocket.java:775) at com.enterprisedt.net.ftp.FTPControlSocket.createDataSocket(FTPControlSocket.java:547) at com.enterprisedt.net.ftp.FTPClient.setupDataSocket(FTPClient.java:2452) at com.enterprisedt.net.ftp.FTPClient.initPut(FTPClient.java:2503) at com.enterprisedt.net.ftp.FTPClient.putData(FTPClient.java:2576) at com.enterprisedt.net.ftp.FTPClient.putStream(FTPClient.java:2309) at com.enterprisedt.net.ftp.FTPClient.put(FTPClient.java:2194).

After sometime if i rettry the same file , it goes through successfully.

Also this behaviour is sporadic, i face this problem say once in 10-15 files .

Can someone please help me out on this.

Answer 3

You are sending NOOP and PWD commands.

The replies from these are getting mixed up with the expected reply to the PASV command, i.e. server responses are out of sequence.

Are you calling these from a different thread? You need to rethink what you are doing here ...
