I'm not much of a Cocoa programmer,
but I did a little sniffing, and I hope my naive outsider questions provoke
some ideas:

- Could you use Cocoa Java classes to
do all this inside Java? Maybe even moving part of it to the java side
would increase the reliability of some of the tasks that are crashing out.
 (Saw an example at http://lists.apple.com/archives/Java-dev/2004/Feb/msg01079.html)

- The apple docs mention that you just
start up a thread and it will have a new nsrunloop. What is the limitation
that is preventing you from doing that? Maybe if you started the thread
on the java side and then launched into JNI it would solve some of your
problems.
  (See http://developer.apple.com/documentation/Cocoa/Reference/Foundation/ObjC_classic/Classes/NSRunLoop.html)

You may also have some luck starting
from the opposite direction; getting things working in a standalone cocoa
app, then either moving straight to Eclipse or moving to a standalone java
app. I've had a lot of success going this route; it helps eliminate some
of the problem variables and and reduces the pain of a crash.

Hi guys,

I think I sent my last email to Mike only, so I thought I'd update the
list with my progress report from 2/6 on the Skype dialer library for
Mac OSX:

I spent a weekend hacking away at the SkDialer JNI library.  I ran
into some problems with the Skype API.

The good news:

I managed to get my libSkDialer.jnilib loaded by your Eclipse plugin,
executing my obj-c code, setting the callbacks correctly and
communicating with them, etc.  So far so good!


The bad news (20h):

The Cocoa API for Skype relies on me having a running CFRunLoop, which
I
can't run in a separate thread due to limitations of OSX (It will run a
little bit, but then crash and die horribly).  I presume that Eclipse
on
Mac OSX would be running a CFRunLoop itself, but if it is, I don't know
how to connect to it. I tried getting an instance of the current loop
using:

NSRunLoop * loop = [NSRunLoop currentRunLoop];

then adding an NSTimer to it, but the timer never fires.  If I add
an:

[[NSApplication sharedApplication] run]

Things work, the timers fire, and the application crashes and burns the
JVM.


I might be able to use an ugly hack of spawning a separate process
(using NSTask) and communicate with it via local pipes (icky) -- but I'd
rather not go this route.  I sent a note about this to the skype
developer forums and I've got the primary developer on my buddy list in
the hopes of catching him online, but so far I haven't got any good
responses.

If anyone knows how I can get at the runloop Eclipse is using, that'd be
great!
