Re: [xmlvm-users] Cross-compiling Java-classes into Objective-C

Hello Panayotis Sorry, but I'm too blind to see it. I can't find any solution for my problem in the documentation. The only thing that I can find is the way how to compile Java-classes into Objective-C and this is exactly the way I've done it. Perhaps my problem was not described clear enough: The process to cross-compile Java-classes into Objective-C-classes works absolutly fine. Theres no error message or something like that. But I don't know how to make a project out of the cross-compiled files on Mac-site. The result of cross-compiling the classes is a folder full of .m and .h-files. So can you tell me how I can get a complete project out of these files? And it's not an iPhone-app what I want to create, if you think so. If there's a fitting part in the documentation, so I wasn't able to find it. So can you please give me another hint? ;) Thank you and sorry to cause you inconvenience.
