It all sounds so reasonable when you say it like that.

Heh, I was just trying to answer Jeff's unspoken question, which seemed to me to be: "why do these three targets exist and what's the ESSENTIAL difference between them (beyond nuance)?" I think Art answered Jeff's other questions admirably.


The question and answer should probably go on your WO FAQ, since it seems to keep cropping up in one form or another.

Now if only we could make the GUI as clear.

I don't think that will ever happen so long as Xcode is being used as the primary IDE for C, C++, Objective C, Java and Python (not to mention, nearly any other file transformation process you care to shove into it).


I think the problem is further complicated by the fact that Cocoa is written in Objective C and Java is a poor relative in terms of Xcode features, functions and, most importantly, documentation.

Doubtless Java is not at the top of the priority list. I wonder how configurable Xcode really is? If the "application name" target could be excluded from that "add to target" dialog, that would vastly improve usability. The choice between Application Server and Web Server is pretty intuitive.


I'm beginning to wish for a WebObjects Xcode mailing list. I've not been particularly satisfied with either the Xcode mailing list, nor with the Apple Java Developer's mailing list, though the latter comes closer to my needs.

My biggest problems with these latter two lists is that they seem to generate about 2 - 5 times the traffic that the WO lists generate and they have a much lower ratio of content-in-which-I'm- particularly-interested to other-stuff (it sounded crass and arrogant when I initially wrote "signal-to-noise-ratio).

Agreed. I am on the Xcode one, but most of the traffic is not relevant to my concerns.

Hi, Jeff,

Actually, the targets in Xcode for WebObjects are fairly straightforward. Xcode is aiming for a split install in deployment where your static HTML files and images (basically, any files that can be served directly by the webserver) are put under the web server root and your code and other resources which can't be vended by the web server are put in the application directory.

A "Target" under Xcode is simply a set of files and the instructions for turning those files into some derived product (typically an executable through compilation and linking). Clearly, it makes sense for Xcode to have the two targets, "Application Server" and "Web Server" to represent the two products it intends to build.

The third target (the project target), named after your application, is an aggregate target simply comprising the other two. It's instructions are simply to depend on each of the other two, so if anything changes in one or both of the other two, it will trigger the building of the one or both other targets.

The project target itself has no content, so nothing should be added to it.

Regards,
Jerry

Thank you, thank you, thank you. I actually did try adding it to both the Application Server and the Applicationname tagets, but didn't try Application Server only. I never have quite gotten my arms around the different targets. Actually I think I have understood them in the past, but by the time I have trouble with them again (like now) I've forgotten quite what the nuances are between them.

Thanks again,
Jeff
