"To get performance boosts out of Java applications, many
developers choose to develop their own object management solutions
to replace the default garbage collector. A common solution is
object pooling. Creating a Java object is somewhat expensive; when
you create objects once and reuse them many times, you reduce the
overhead. This makes sense, particularly in server-side
applications, as the same server code is normally executed
repeatedly. For applications that run in a single Java Virtual
Machine (JVM), such a solution is normally simple. In a
multi-tiered architecture, however, managing object instances
across multiple machines and multiple JVMs can be quite

objects in a multi-tiered J2EE architecture..."
