I'm happy to take the "pre-built" DartServer.jar for now, and maybe for the
foreseeable future. How do we proceed with this? Where can I get it? I
think I may still want to run the self/unit tests on it, nonetheless (and
your debugging tips will probably come in handy here), if possible.
Additionally, client-side construction will be the next task. I haven't
read up on that yet, but I assume that can be found somewhere in
<http://svn.na-mic.org:8000/svn/Dart/trunk/Dart.pdf>?
I'm still a little fuzzy on what exactly the client is and what it depends
upon. I suspect there's some SOAP/XML-RPC based protocol going on from
client to server, and the client can be constructed however one desires so
long as it implements said protocol? Are there multiple clients? Are they
all Java based? Are they pre-packaged? Which platforms, if so?
I suspect many if not all of these questions are address somewhere...I just
haven't found that somewhere yet. Care to point me in a good direction?
Also, I'd be inclined to say Java is a good way to go for
Dart. Development in Java (it's conterpart, .NET and related things like
Mono) goes faster, and as you noted, you can create more features in less time.
It's us poor, ignorant Java users that have problems, but we can get over
that. :) I'll be trying out your ant debugging suggestions soon...unless
I just bypass it and use your server .jar without running any of the unit
tests.
