If it's a servlet app, then the runtime is created in CayenneFilter and
bound to the thread for each request and you access it via
WebUtil.getCayenneRuntime(servletContext);
Or you can get a context from the injector if you have bound that to a
thread:
ObjectContext context =
CayenneRuntime.getThreadInjector().getInstance(ObjectContextFactory.class
).createContext();
If not a servlet app, then yeah, I'd just store it in a static variable or
application instance.

Thanks,

We avoid storing it as a singleton and use the same concept for non web
apps using BaseContext
<http://cayenne.apache.org/docs/3.1/api/org/apache/cayenne/BaseContext.html>BaseContext.bindThreadObjectContext(context)||
context = BaseContext.getThreadObjectContext()
So you usually just bind the context on startup and don't need to have
write your own singleton for that.
Indeed we made a DAO Template that works in both scenarios to be able to
reuse the dao library.
