Hi,
I assume that you are using XCode 1.5? If so, read the release notes carefully, they'll tell you which files you have to move where in your D2W project after you start it. The MenuHeader.java is for sure one of the files that is misplaced under the target folder.

I am trying to get something going here. I couldn't get my D2W application to not blow up; so I went back to the tutorial, and it BLEW UP, ah..raised exceptions:
Error:

Is this typical? that the TUTORIALS explode? The tutorial for D2W, of course, talks about project builder, but I don't think that is an option, is it? Is that because the documentation for WebObjects has not be updated for Xcode? The tutorial is:
http://developer.apple.com/documentation/WebObjects/Developing_With_D2W/index.html#//apple_ref/doc/uid/TP30001015
I am osx 10.3.5 and WebObjects currently v 5.23 and v 1.5 xcode ide, Java 1.42. It could be just my machine....or is it everybody's?
The release notes for D2W say:
Radar #2274611
DirectToWeb raises on custom or non-existent keys.
Description:
An EOUnknownKey exception can be raised when you run a DirectToWeb application. This behavior is due to either a mistyped key in the Web Assistant or the removal or renaming of an attribute or relationship in EOModeler.
Workaround:
Using the Web Assistant's expert mode, select the task/entity pair for which you're getting an exception and hide the key that is causing the problem.
I can't even get to the web assistant.
My machine did have older software which has been upgraded (Jaguar to Panther), could that be the problem? Would re-installing everthing from scratch allow D2W to work? or is this up to Apple to fix?
Thanks to all for your attention.
