  • Why doesn't my application launch into my browser?

Go to start of metadata

Discussion: You select 'Run as...' -> WOApplication; the project runs; you can copy the url out of the console and into the browser; but it doesn't conveniently launch straight into the browser anymore.

Solution: You probably have a space in your Eclipse project name; eg. 'My Project' remove it, or replace it suitably, eg. 'My_Project' and it will probably all start working again. (tongue)

Discussion: Presumably, the launch fails because the Eclipse project name automatically forms part of the URL for running the application as a WOApplication in Eclipse/WOLips. However, a space is not a legal character for a URL as we know, and must usually be escaped with UTF-8 encoding as '%20'.

Leopard is missing WOOpenURL

WOOpenURL only exists in WO 5.3.3 and lower versions of WO. WO 5.4.X does not use WOOpenURL file, which incidentally existed to provide cross-platform launching. In WO 5.4.X, the method com.webobjects._ideservices._WOLaunchServices#_openURL now determines the logic for auto-open-in-browser. And if you could look at the source code, not that I would of course, you would notice that it just calls /usr/bin/open instead. So if you want auto-open-in-browser to launch a different browser than your default (for example if you use FireFox for development and Safari as your default browser) you will have to write a patch for this class and insert it in classpath ahead of the built-in one.

If you are on Leopard, something else is going on.

There used to be an application called /System/Library/WebObjects/Executables/WOOpenURL that opened the standard web browser with a pointer to the running the project, eg:

That application does not exist any more in Leopard. But there is a simple workaround:

Type this in a terminal as root (or precede with sudo).

mkdir -p /System/Library/WebObjects/Executables
ln -s /usr/bin/open /System/Library/WebObjects/Executables/WOOpenURL

WebObjects 5.3.3 on Leopard

If you change the wo.wosystemroot setting to use WO 5.3 frameworks from a different location than /System/Library/Frameworks, you will need to also change the location of the above hack. e.g.


Requires this change:

mkdir -p /Users/chuck/Library/WebObjects/Executables
ln -s /usr/bin/open /Users/chuck/Library/WebObjects/Executables/WOOpenURL
