[tcljava-user] exec question

[Tam H. <th...@su...>]

How do i go about getting the return value from executing the exec command
in jacl?  I have try the following in the tclsh which work but doesn't work
in my java program..

shell:
catch {exec tclsh83 script.tcl} s
puts $s


java:
Interp interp = new Interp();
String testing = "set res [exec tclsh83 D:/Tcl83/bin/scripts/script.tcl]";
        interp.eval(testing);
        interp.eval("puts $res");
