Problem running a native executable

[glhenni@xxxxxxxxxxxxx (Gary L. Hennigan)]

I'm trying to do something very simple, have my Java code execute the
command:

netscape -remote 'openFile(/tmp/file.wrl)'

It works perfectly from the command line, and I can easily invoke
netscape with:

netscape file:/tmp/file.wrl

from my Java code, but put the "-remote ..." in there and it won't
work.

Netscape reacts to it, because I can minimize it before Java invokes
it and it pops up when Java executes it, but netscape beeps and
doesn't do the "openFile()". Here's the Java code snippet I'm using:

    // Bring up a picture in Netscape
    String cmdLine = "netscape -remote 'openFile(/tmp/file1.wrl)'";

    try {
      System.out.println("Trying to run:\n" + cmdLine);
      Process nsViewer = Runtime.getRuntime().exec(cmdLine);
      InputStream nsErr = nsViewer.getInputStream();

      int c;
      while ((c=nsErr.read()) != -1) {
        System.out.println((char)c);
      }
      nsViewer.waitFor();
      System.out.println("Exit value of Netscape was: " +
                         nsViewer.exitValue());
    }
    catch (Exception exc) {
      System.err.println("Error running geometry viewer!");
      System.err.println("Error: " + exc);
    }

I never get any output from the processes InputStream (or the
ErrorStream, which I also tried) and the exitValue() always returns 0,
but it doesn't bring the file up.

I suspect something along the line is getting confused by either the
single quotes or the parens but escaping the single quotes with a "\"
yields the same behavior.

If anyone has suggestions they'd be appreciated!
