Hey Manik, I know you were planning on working with integrating the eviction and marshalling regions this week. Here's some input based on stuff I'm doing on converting the EJB3 code to use the 2.0 API. 1) Once I call Cache.getRegion(fqn, true) I've created a Region, but I'm not sure how to set it up programatically to do eviction. Passing a config to setEvictionPolicyConfig() seems obvious. But would that be enough to get the eviction policy created? Or should I then call activate()? The javadoc implies that activate() pertains to marshalling, but does it make sense to make it apply to eviction as well -- a sort of general purpose start() method? 2) Conversely, how to remove a region when an SFSB is undeployed? There's no Cache.removeRegion(Fqn). There is a deactivate() method. I realize this stuff may not be implemented; I'm more concerned with understanding the API.
