Hi Tore,
Probably won't be able to help with the coding tasks, but I'll be
happy to help with server issues.
* The webpage http://www.bluebearstudio.com/hessianobjc/ are not
working today :( php error..
Hmm... I wonder if we should try the web service connector developed
by Michael Victorov. SOAP is heavy, but at least serialization is
predictable.
I am using axis tcpmon to debug the network traffic. It is very
useful as the hessian protocol are almost readable for a human. I
start it with " java -cp axis.jar org.apache.axis.utils.tcpmon 8090
localhost 8080". The server are listening on port 8080 and the
client are connecting to port 8090.
This is a useful suggestion. Probably would be a good idea to stick
this somewhere in the Wiki documentation.
My current status is that I am able to execute a NamedQuery and use
the result to fill up a NSTableView using an NSArrayController with
Artists from the rop-tutorial. None of the other stuff are working.
Like relations, persistent state, graph diff, committing, events.
Puh, a pretty long list.
One thing that I had to do in Cayenne is custom (de)serializers
(different on the server and on the client). Check out
org.apache.cayenne.remote.hessian.ClientSerializerFactory - it has
all the client stuff. I guess we may use a similar approach in ObjC.

Hello.
I have tried to start connecting cocoa/objc to cayenne. As I am new
to all of this, I would realy like to get some help.
First, The hessianobjc framework are easy to use, but should
probablye have a couple of improvements. Here are my hessianobjc
notes:
* The webpage http://www.bluebearstudio.com/hessianobjc/ are not

* Do not know how to do basic authentication. turned off on server
for now.
* Basic classes like Map, Double, String etc works out of the book.
* Apply a Dictionary (Map) that are used to map between java class
names and Cocoa class names.
* Other classes (that are not simple like Double and String and
not mapped) are returned as NSDictionary with a special entry named
"hessianClassName". That is very cool as the key-value stuff make
all classes usable out of the box.
* Some arrays like GenericResponse.results has 3 (ca) rows in
front with NSError objects. After that the normal result rows are
coming. Strange. Here are some examples of the NSError objects:
- NSError "Unknown tag returned from server "
Domain=BBSHessianObjCDomain Code=666 UserInfo=
{NSLocalizedDescription = "Unknown tag returned from server "; }
- NSError "Unknown tag returned from server "
Domain=BBSHessianObjCDomain Code=666 UserInfo=
{NSLocalizedDescription = "Unknown tag returned from server "; }

Pri 1 TODO:
* fixing the NSError stuff. Perhaps by just filtering those
objects out?
* refactoring. should probably prefix all classes with CAY or
something.
* commit to sandbox
* relations/faults
