Trying to launch Acrobat or Preview to open a PDF

Hi guys,

I'm trying to launch either Adobe Acrobat or Preview.app from my Java application so I can display a PDF file to the user. I'm doing this on Mac by using Runtime.exec to invoke the open command.

I've tried various different open commands through the following code:


private static void launch(String fileName, String applicationName)
{
String cmd = "open " + fileName;
try
{
System.out.println("Executing command: " + cmd);
Runtime.getRuntime().exec(cmd);
}
catch (IOException e)
{
JOptionPane.showMessageDialog(null, "Could not open " + applicationName);
e.printStackTrace();
}
}

Whatever I set cmd to, nothing happens. The application doesn't launch, I don't get an error message or exception, it just silently fails.

Two odd things:

1) The same code opens my default web browser just fine if I pass a URL to this method in the fileName parameter

2) If I invoke the exact command that's println'ed out from Terminal, then the PDF file is opened as expected, so the filename (which is an absolute path) is valid.

Can anyone offer any clues about this? What have I missed?

Many thanks as always,

Dan
