Response to: Direct to Web java.lang.ClassNotFoundException: Application error
Managed to fix my problem. I went through the XCode 1.5 documentation and saw that they had an issue with generating D2W projects, by not placing two java classes in their proper place. After changing that in my projects I now can get what the tutorial says i should get. Maybe now i can continue learning... Thanks for your assistance, ' Regards, F

  I would like to know in details, what you did to overcome this issue. I have the same problem with my D2W application and all the samples. I appreciate any help!

  From the release notes:
  
  For Direct To Web projects: When creating a new Direct To Web project, you'll notice that the MenuHeader.java and PageWrapper.java 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 MenuHeader.java and PageWrapper.java source files from the Bundle Resources build phase to Sources build phase.
  
  Instructions, as explained by Andres Toussaint on the Apple WebObjects list:
  
  'After you create your D2W project in xCode, open the contents of the "Targets" group (a red bullseye).
  
  Double click the "Application Server" target.
  
  Select "Build Phases". In the right hand you will see the build phases, indicated by "Sources", "Bundle resources", etc..
  
  Drag the MenuHeader.java and PageWrapper.java from the Bundle Resources to the Sources.
  
  That is all.'
  
  HTH.
