launching browser from Java on headless sever

I have a web based app that I need to launch from time to time using Java. The app only runs in a browser window so I need to get that running. I used OS X for my development and it runs fine on my laptop running the server on localhost. But when I deploy (in an oc4j container in a Solaris environment), the browser launch always fails. I think it is a DISPLAY issue but my UNIX is so rusty that I'm not confident about that. Here is the command I'm using to launch the browser in Java:

Code:

// my first attempt, commented out here but left for reference
// String cmd = "/opt/sfw/bin/firefox "+ url;

// my latest attempt
String cmd = "DISPLAY=:5 /opt/sfw/bin/firefox "+url+" -width 1600 -height 1200";

Runtime rt = Runtime.getRuntime();
Process p = rt.exec(cmd);

current error message looks like this:

Code:
