I am new to java program and debugging an existing code. This code is to FTP a file to the mainframe system. This code works perfectly if the running environment is windows but it fails in Unix (It is prompting for the password). I am here by pasting a part of the code. If anyone has input please help me.
This is the serious action taking place in the windows platform

Inside DoCommand pass er2$dr01 Inside getreply 331 Send password please. Inside DoCommand site blocksize=9320 lrecl=932 recfm=vb
This is the serious action taking place in the unix platform. I am getting a null value instead of (331 Send password Please).
