I've had strange WO behavior if I would disable my ethernet network interface. Never exactly what you are getting, but I would stop being able to access my server apps from my client apps. I don't think the behavior is 100% reproducible. So, perhaps the behavior you are getting is not per se related to being connected to the internet, but to having any network interface enabled. I speculate that when there is an IP assigned to your machine, WO apps are mapped to that IP, and if your network interface is disabled, 'localhost' can not be translated to that IP, thereby rendering your WO deployment useless. Does this make any sense?

Have you ever tried turning off your airport (or any other relevant network device), then restarting the machine, and then trying to do WO stuff?

I'm encountering something very odd, and before I debug it I'd like to see if this has happened to anyone else.

I have a Wonder Application that runs just fine as long as I am connected to the internet. If I disconnect (say, by turning my airport off), I receive the following message in my browser when I launch the application:

Application: MainBundle
Error: java.lang.IllegalStateException exception
Reason:
java.lang.IllegalStateException: An Exception occurred while generating the Exception page 'WOExceptionPage'. This is most likely due to an error in 'WOExceptionPage' itself or WebObjects encountered an uncaught exception while creating a Session object.



Below are the logs of the original Exception which occured in com.realtor.dolphin.app.Application, then the later Exception in WOExceptionPage.


Original Exception:
java.lang.IllegalArgumentException: <com.realtor.dolphin.app.Application> Class 'Session' exists (interface org.apache.axis.session.Session) but is not a subclass of WOSession.

Why is the behavior dependent on whether I am online or not? It would be nice to be able to run & debug purely locally, especially while on an airplane.

I would suspect my classpath, except that does not depend on my online status.

Any ideas?
