The complete instructions on creating and exporting a Beekit project into Codewarrior, can be found in the Beekit User's Guide. As mentioned earlier, there is also an 'import' action that must be carried out from Codewarrior, after Beekit has exported.
after you have generated a project with Beekit, you could export it (Beekit menu: Solution and Export Solution) from Beekit.
After this step, you could open Codewarrior and in menu File select Import Project and select the folder where Beekit generated the project and choose the file *.xml and after choose the name of the project. At this point, I think you should see your whole project loaded in codewarrior.
If this info are not so clear, you could find some information in the guides in the beekit's folders.
