opening IE window from JAva Application

[Patrick]

Im writing a java application (standalone, not applet) and Im trying to get
it (the application) to open an IE window or NEtscape and get it to load
a url from the program..
(program sends URL to broswer, and opens a new one if browser window is not
open)

Is this possible to do? if so, any help or suggestions..
thanks

The following code works on my Windows system:

public class StartBrowser extends Object
{
static public void main(String args[]){
try {
Runtime.getRuntime().exec("start
http://antwrp.gsfc.nasa.gov/apod/astropix.html");
} catch(java.io.IOException e) {}
System.exit(0);
}
}

I believe the RunTime Object will do what you want (i.e. execute an external
program); but it won't be portable.

I am actually getting an IO Exception when I try this code. Any suggestions?

The exec() method will throw an IOException if the command you give it to
execute is invalid. This could happen if your PATH doesn't contain the
directory that includes the Windows program START.EXE. That's
C:\Windows\Commands on my Windows/98 system.

Try the following code:
public class Browser {
public static void main (String argv[]) throws Exception {
Runtime.getRuntime().exec
("rundll32 url.dll,FileProtocolHandler http://www.yahoo.com/");
}
}

Thanks

I have used both "rundll32 url.dll" and "start", and have found that "start"
was working in more cases than the other one.
There are several issues with the Runtime object you have to take into account.
First of all the exec() command does not recognize built-in commands (like
dir, and possibly start also).
The only way to get around is by starting up the command.com from the exec()
method, and then sending any commands to the output stream you get from the
Runtime Object.
It is a bit dirty working with the runtime environment.

Remove the "start" from the exec() function leaving only the url as a string.
This will make to code above work. It worked for me so I hope this helps.
