Re: install with embedded frameworks
I think I understand better now. The frameworks exist, and the WebServerResources are there for javaclient, so they're included. I added this to the copy section of the split target of my build.xml file exclude name=Frameworks/*.framework/WebServerResources/Java/**/ And it looks like that will do what I want (getting rid of the java files, but including the images). Does anyone know a reason that's a bad idea (This is a plain old web app).

Programmatically changing database configuration on startup
Hi all, we are currently trying to make our deployment work nice. A problem we currently have is, that we have different database connection configurations in the EOModel of our Application (one for deployment and one for local testing).

Re: Dr. Miguel 'Optimistic Locking' Arroz [was Re: WebObjects stress Testing tool?]
Hi Kieran,
I have a multi-threaded app and I'm starting to run into deadlock issues on EC
locking/unlocking (OSC really). After a weekend of digging and researching I
think your solution is the answer.
Question #1: Is this the final, dust-settled version?
Question #2: Do you always use a new EOObjectStore in your threads? It seems
your implementation depends upon it. If so, what's your philosophy on how many
you create and how long they live? I have tens of thousands of threads running
per instance per day (only a few at a time) and something tells me creating a
new OS for each is a bad idea.
Thanks,

No. In have a pool of OSC's dedicated to background threads. Usually 4 to 12 in

WKObjectStoreCoordinator is just a simple subclass that allows me to give the

Fwd: Programmatically changing database configuration on startup
Sorry, but i forgot to forward the answer on my past question to the whole mailing list. Here is my answer again for all other people which are investigating the same issue. Thank you for the quick help. I'm ended up with using the wonder property dbConfigNameGLOBAL.

within a couple of days. I have deadlocks on at least a daily basis so if
those disappear it will be another validation of your work... not to mention
once again earning my gratitude.
