Open a browser window from a Java program

Question

I have an application written in Java. It is designed to work offline on a Linux box. I am trying to create a new firefox window. However, firefox never opens. It always has a shell exit code of 1. I can run the same code using gnome-terminal, and it opens perfectly.

Background

So here is his initialization process:

  • Start X "Xorg: 1 -br -terminate -dpms -quiet vt7"
  • Window Launch Manager "metacity --display =: 1 --replace"
  • Configuring xrdb -merge / etc / X11 / Xresources resources
  • Become a demon and disconnect from the control terminal

As soon as the program starts, a button will appear that the user can click to display the firefox window. Here is my code for this. Remember that X is on the display: 1.

code


public boolean openBrowser()
{
  try {
    Process oProc = Runtime.getRuntime().exec( "/usr/bin/firefox --display=:1" );
    int bExit = oProc.waitFor();  // This is always 1 for some reason

    return true;

  } catch ( Exception e ) {
    oLogger.log( Level.WARNING, "Open Browser", e );
    return false;
  }
}
