From the release notes:;


Known Issues
 • If you create a new WebObjects Java Client, Direct To Java Client or Direct To Web application with Xcode 1.5, the project will not configure the build targets correctly. You will notice that some files are not properly added to the Application Servers target, nor are they part of the proper build phases, which will cause issues when building. This bug will be fixed in a future update of WebObjects.

◦ For Direct To Web projects: When creating a new Direct To Web project, you'll notice that the <x-tad-smaller>MenuHeader.java</x-tad-smaller> and <x-tad-smaller>PageWrapper.java</x-tad-smaller> source files are not correctly added to the Application Servers target and are in the Bundle Resources build phase and not in the Sources build phase. After creating a new project, open the Application Servers target in the Groups & Files view and drag the <x-tad-smaller>MenuHeader.java</x-tad-smaller> and <x-tad-smaller>PageWrapper.java</x-tad-smaller> source files from the Bundle Resources build phase to Sources build phase.

Hi all,

I'm a newbie when it comes to WebObjects and XCode (not new to Java
dev). I've been following some tutorials to get a hang of WO. All is
well until I tried to create a Direct To Web application in the
following tutorial: http://www.beedocuments.com/databaseDesign.html
(also try http://developer.apple.com/documentation/WebObjects/Developing_With_D2W/Introduction/chapter_1_section_1.html
with same result)

It's basically, a very simple Direct To Web application. I can build
and launch it, but when I try to login I got an exception (stack trace
included at the end). It looks like a classpath problem. It's
complaining about missing MenuHeader and PageWrapper classes. Not
being familiar with XCode, I'm not sure how to fix it. Aren't those
classes supposed to be added automatically to the classpath? What am I
missing? Any help is greatly appreciated. Thanks.

My dev environment:
Mac OS X 10.3.8
XCode 1.5
WebObjects 5.2.3
OpenBase DB 8.0.4
