e the object... } catch(Exception e) { //...handle any exceptions... } finally { // make sure the object is returned to the pool if(null != obj) { pool.returnObject(key,obj); } }

{@link KeyedObjectPool} implementations may choose to store at mostone instance per key value, or may choose to maintain a pool of instances for each key (essentially creating a {@link java.util.Map Map} of{@link ObjectPool pools}).
