   |  Hello, I have tried to identify whether or not a remote command
   |yield an error, using the set/getErrStream, but no matter what i
   |did, the only thing i can do is to print the error message.

   |I tried the following:
   |InputStream err; Channel channel = session.openChannel("exec");
   |((ChannelExec)channel).setCommand("dummy");
   |((ChannelExec)channel).setErrStream(System.err);
   |channel.connect(); err = ((ChannelExec)channel).getErrStream();
   |if(err.available() != 0) System.out.println("error");

That should be 

   InputStream err; 
   Channel channel = session.openChannel("exec");
   ((ChannelExec)channel).setCommand("dummy");
   err = ((ChannelExec)channel).getErrStream();
   channel.connect();
   if(err.available() != 0) System.out.println("error");

, but 'err.available() != 0' depends on the timining.
You shoud wait for the termination of remote exec and
then check 'err.available()'.

Thanks,
