For a stateless or entity bean, after an object is utilized for some action or business process, it is sent back to the container so that it can be reused. However, when the object is in process, the container may recreate more objects in the pool so that when this particular object is returned to the container the container may not be able to accept it because its pool size is full. Hence these objects are discarded. This metrics depicts the number of such objects. |
