We have the JMS change notification framework in place that we need to
replace with the Jgroups implementation.
We are not using Project Wonder.
I am trying to decipher the necessary steps to incorporate this framework
into our existing apps. There really isn¹t any docs that explain the
functionality of this so I have had to figure out things based on the code.
Here is what I think I need to do. If someone can validate this list it
would be appreciated
1. Need to incorporate ERJGroupsSynchronizer.framework into my code.
2. Looks like I need to call out ERJGroupsNotificationCenter.install() early
on in my application initialization. This appears to create a subclass of
the NSNotificationCenter. It seems that this needs to happen before the
model gets loaded.
3. Then it looks like I need to call out
ERXObjectStoreCoordinatorSynchronizer.initialize(). This looks like it needs
to happen before any models get loaded.
4. Once I get a reference to a ERXObjectStoreCoordinatorSynchronizer then I
can create a ERJGroupsSynchronizer.
It seems that there must be some other steps that Wonder does that I might
need to replicate. I saw a reference to ERXDatabase. Somewhere I would need
to hook in and create a subclass of EODatabase I would imagine.
Would it be possible to integrate Project Wonder without destroying my whole
application? We have a base class that inherits from WOApplication (actually
some thing like)
WOApplication
foundation.Application
services.Application
myapp.Application
Can I simply change my foundation.Application to extend ERXApplication? Will
that initialize the other parts of the stack properly? We don¹t have the
ability to gut our application too much at this point.
Thanks in advance for any tips
