How to pass email message body to qmail-inject in Java

[ann wang <naannwang@yahoo.com>]

Hi, 
 
I am using "Runtime.exec()" to run 
 qmail-inject
 and give it the message either from a string or file.
I have to pass the message
 body to qmail inside java, how would I do it. I am
 desperate since it won't read anything from
 message.txt, it just won't read < message.txt.
 It end up sending a blank email.
  
   Process proc =
 runtime.exec("/var/qmail/bin/qmail-inject
 naannwang@yahoo.com < message.txt");
 
 Thanks ahead!
