The interp.getResults will not give you the output from puts command.
it contains only the results of a function call/expression evaluation.
which is different from writing to stdstreams.

to capture the error information, this is what is done in the Shell,
try {
    ...cmd evaluation..
} catch (TclException e) {
    switch (e.getCompletionCode()) {
        case TCL.ERROR
            println(errstream, interp.getResult().toString())
    }
}
so yes, it is the same message.

You can capture the puts output by changing the stdstreams in java.
Take a look at extras/GuiShell/GuiShell.java: setupStreamReaders. You
can see how the streams are diverted.
