Hi List,
I maintain a separate framework containing the model definition
which has worked well.
My powerpc g5 recently died so I have switched to another Mac. In
development all is well, but on deployment I now get this:
...

file:/Library/Frameworks/InraxEOModel.framework/Resources/
Inrax.eomodeld ) )>

[2009-6-25 11:42:8 GMT] <main> Waiting for requests...

The first line correctly shows the InraxEOModel.framework where the
model is lurking but then later it fails to connect. Under what
circumstances might the model framework be found ok, but the
database connection fail (when I know the database is ok)?
I don't think the fault lies with the model framework because I can
use this newly deployed framework with the previously deployed
applications and it works fine.
So something must have changed in the way the newly built
application tries to do the database connection (works in
development, not in deployment).
Is there any more logging I can do, or checks within the deployed
application files to see what is causing the failure.
I have moved to the latest stable wolips which may be one
difference, though I was already on the hotness.
Thanks,
John
