reading stderr and stdout in tcl

[masssmith]

Hi,
I am a newbie to this forum and to tcl. I wrote a java program that writes output to stderr and stdout. I executed this program in tcl with the exec command. Now I want to read in the information from that stderr and stdout in the tcl script.
Any ideas?
Thanks a lot!

Unless you've overwritten the standard stderr and stdout, I think they are volitile streams in the shell, itself. That is, I don't think they exist for Tcl read once the java program has ended. You'd be better off directing them to a file and reading that file with Tcl.
