I just researched this a couple of days ago. You might try this on a Windows platform.
Attached are two files. One is a Launcher class that launches a browser for
you and the other contains my notes after searching the web for this stuff.
Example Invocations:
Launcher.launchBrowser("http://www.intellij.com/eap/downloads";);
Launcher.launchBrowser("mailto:[EMAIL PROTECTED]";);
It also handles things like Telnet, too. This truly is telling windows to
launch the application associated with the protocol...
Let me know if it works for you.

Subject: [Eap-list] Off topic: popping up an external browser
Hi,
I know this is a little off the topic of this list, but since I have no
major complaints or suggstions about Idea 2.5 (other than wanting
support for javadoc comments and renaming a property variable should
also rename setters and getters), I thought I would ask this question:
How does Idea pop up the browser for help? I am not concerned with how
it determines the url. Rather I want to know what java code I can use
to launch a new browser for a given url. I have code (I think I first
saw it on JavaWorld's web site) that uses a system call with the command
cmd = "cmd.exe /c start " + url.toString();
But this does not bring up a new browser on top of the other windows
like Shift-F1 does in Idea. I would appreciate any help on this.
Thanks,
Phil
