This is probably something I should know, but I don't :) We have 150 users on an app that we're scaling to a couple thousand across a few servers. We _were_ using EclipseLink's topic based jms cache coordination, but we're found that it's leaking memory as of late from some strange interaction between ActiveMq and EclipseLink.
At runtime, we'd have all of the persistence.xml files on the classpath, but we really wouldn't know all of the persistence units until the app is launched. I noticed some information about PUs are available in JMX, so I was curious if we could create an EntityManager or EntityManagerFactory dynamically given a unit name. Is it possible to lookup a persistence unit in JNDI perhaps? Thank you, -- Jonathan | [email protected] Pessimists, see a jar as half empty. Optimists, in contrast, see it as half full. Engineers, of course, understand the glass is twice as big as it needs to be.
