[tcljava-user] HELP...Calling TCL scripts from a Java program

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

I'm trying to execute a Tcl script from a java program using the java
Runtime class.  However, the script does not execute because my log file is
never created.  Should i stick to this Runtime class or use something like
Tcl blend to include a class to call the script.  I'm just trying to find
the quickest solution to call the script, pass it parameters, and get
results from the script in return..Am i even calling the script the right
way?


Any suggestions would be appreciated!!


TCL SCRIPT:
set f "log.txt"
set out [open $f w]

puts $out $argv0
puts $out $argv1
puts $out $argv2

close $out


JAVA PROGRAM:
  public static void main(String args[])
    {
        try
        {
            String s;
            String[] argv = {"hey", "there", "buddy"};
            String[] cmd = new String[2];
            cmd[0] = "d:\\Tcl83\\bin\\wish83.exe";
            cmd[1] = "d:\\cygwin\\bin\\hello.tcl";

            Process myProcess = Runtime.getRuntime().exec(cmd, argv);
            myProcess.waitFor();
            System.out.println("Process exit code is: " +
myProcess.exitValue());

            DataInputStream in = new
DataInputStream(myProcess.getInputStream());
                 while ((s = in.readLine()) != null) {
                    System.out.println(s);
                }
        }
        catch (Throwable t)
        {
            System.err.println(t);
            t.printStackTrace();
            //Ensure the application exits with an error condition.
            System.exit(1);
        }
    }
