Performance evaluation of REK supported logistics system

We explore by design and implementation the applicability of J2EE architecture in supporting web-based services. This has been demonstrated by implementing a cargo-container, logistics system. The goal of the cargo-container system is to improve the efficiency of the logistics system by reducing the, overall time and cost. used to create documents and retrieve information. A new software infrastructure was proposed and implemented, performance evaluation was presented. In particular, we investigated the overheads associated with different components of the underlying J2EE architecture, which includes the Session Bean,Hibernate O-R mappings, and the database. We found that the latency overheads introduced by these components account for 5.65%, 1.8%, and 92.55% of the total-delay experienced inside the J2EE architecture respectively.
