Jython FTP Error in ODI

Question

Hi All,
I am using jython code to ftp to a server. When i hard code the username and password it works fine, but when i try to read the username and password from a file, it doesnt work, i get the following error:
org.apache.bsf.BSFException: exception from Jython: Traceback (innermost last):

Below is my source code :
import snpsftp
fsrc = open('C:\ODI\DebtorInfo_Properties2.txt', 'r')
ftp = snpsftp.SnpsFTP(fsrc.readline(),fsrc.readline(),fsrc.readline())
ftp.setmode('ASCII')
ftp.mput(fsrc.readline(), 'DEBITEUR.dat',fsrc.readline())
ftp.close()
fsrc.close()
My file structure looks like this :
100.200.3.45
username
password
C:\ODI\oracledi\demo\file
/ftpfolder/share/
I tried reading the file and writing the file to verify the data is correct and it is. If i hard code the username and password, it works fine e.g.
import snpsftp
fsrc = open('C:\ODI\DebtorInfo_Properties2.txt', 'r')
ftp = snpsftp.SnpsFTP('100.200.3.45','username','password')
ftp.mput('C:\ODI\oracledi\demo\file', 'DEBITEUR.dat','/ftpfolder/share/')
ftp.close()
fsrc.close()
Any help on this matter would be much appreciated. I have been struggling with this for the past 2 days. Im new to ODI so any help would be greatful
Thanks

One of the best ways of debugging jython code is to use the print statemnent.
I suggest that you change the code to something like:
import snpsftp
fsrc = open('C:\ODI\DebtorInfo_Properties2.txt', 'r')
ftpserver=fsrc.readline()
username=fsrc.readline()
password=fsrc.readline()
print "ftpserver '%s'" % ftpserver
print "username '%s'" % username
print "password '%s'" % password
ftp = snpsftp.SnpsFTP(ftpserver,username,password)
ftp.setmode('ASCII')
ftp.mput(fsrc.readline(), 'DEBITEUR.dat',fsrc.readline())
ftp.close()
fsrc.close()
Run it in an agent, and you will the print statements in the agent log. You may need to strip() what you read from the file.
