Thanks Viet,

I got your idea and looked over the example code. However I am looking for any 
short solution for this. Basically the example code 
(http://www.jcraft.com/jsch/examples/Exec.java.html) line no 67 has following 
line-

((ChannelExec) channel).setErrStream(System.err);


Now I have a modified class of Exec.java which uses log4j logger like this-

import org.apache.log4j.Logger;

public class Exec{
    private static final Logger logger = Logger.getLogger(Exec.class);
    public void execute(){
        //All of the JSch errors are now written to System.error stream
        ((ChannelExec) channel).setErrStream(System.err);

        //Instead of above line, how can I write these errors to logger
        logger.error(/*set error stream to this*/);
    }
}

How can I achieve this implementation?

Hi Ravi,

1) Create your own Logger class that implements com.jcraft.jsch.Logger and uses 
log4j
2) Apply your Logger using 
com.jcraft.jsch.JSch.setLogger(com.jcraft.jsch.Logger) method
Check Logger class of JSch example for reference.

Hope this helps.

Regards,
Viet

Subject: [JSch-users] How to set ChannelExec error stream from System.err to    
log4j
 


Hi,

I want to execute a command to remote linux machine. I am referring Exec.java 
(http://www.jcraft.com/jsch/examples/Exec.java.html) example code.

I just wanted to know How to set ChannelExec error stream from System.err to 
log4j, so that all of these errors, I can get captured by log4j under error 
catagory.
