FTP'ing files onto a UNIX machine using JAVA

[Ravi Pydi]

Hi,
I am trying to FTP a text file from a AIX box to a UNIX box using JAVA. I already have a code which can FTP files into a Windows environment. I am using the same code to log into the Solaris box. I am able to log into the system by using the doCommand() method (see code below) but the same code isn't working in the ftp session. I am getting "Get option: single" as a response when I execute any command after logging in. But the same doCommand() method after logging in works fine on a windows box.

The method that is trying to execute the commands on the UNIX server is as follows:

public String doCommand(String commandString)
throws IOException
{
outStream.writeBytes(commandString+"\r\n");
String response = getResponse();
System.out.println("The response from the Mailbox server is : " + response);
return response;
}

Any suggestions on this is greatly appreciated.

Thanks
