Subject RE: Logging messages directed to stdout

I did refer to your two week old reply for a similar question.
 
I am able to write a java program (say program2) , which redirects stdout & stdin to log
file.
 
But, I am not sure, how do I redirect the stdout of already running program (JVM)  to stdin
of my new program (JVM). Should I use pipes ?  
 
If will be helpful, if you could provide complete syntax of the command.
 
 
Please note that I donot have the option to modify the source of the already existing java
program (say program1). 
 
Thanks

Not possible: unless you get a faster machine :p

I seem to answer this question every week - it isn't hard to redirect
stdout and stderr and any programmer should able to do it.
