Subject Re: ObjectContext & Factory
Date Thu, 16 Aug 2007 21:21:24 GMT
More to the point ... The two ways to instantiate DataContext  
provided by Cayenne framework that are using DataContextFactory  
behind the scenes (DataContext.createDataContext() and  
WebApplicationContextFilter) may need to be migrated to something  
that returns ObjectContext instead. But keep in mind that those are  
just utilities and you don't have to use them (and  
DataContextFactory). You can create your own context in your code,  
skipping the factory.
