Subject [exec] Using Commons Exec to Input a Password to a Shell Script
Date Mon, 11 Oct 2010 20:21:00 GMT

We are trying to use Apache commons exec to execute a shell script which 
takes several inputs, one of which is a password which is not echoed to 
stdout for security purposes.  We were using the PumpStreamHandler and 
using a ByteArrayInputStream object as the InputStream parameter for the 
PumpStreamHandler constructor.  The clear text inputs are working as 
expected but we are not able to progress after the prompt for the 
password.  Do you have any suggestions on how to approach sending a 
password via commons exec?
