When independent business components must be executed simultaneously, the parallel processing of application business logic has a direct impact on the performance of the system; however, parallel processing at the application level historically has been challenging to implement. In the case of J2EE applications that rely on the services provided by the application server containers, implementing parallel and concurrent processing is an uphill battle. Over time, the Java messaging services (JMS) API has become a de facto solution for parallel business logic processing by utilizing the asynchronous messaging features offered by the API. Although JMS provides a solid foundation for developing J2EE applications that use asynchronous messaging, it does not automatically produce the desired end result. JMS poses the following challenges: JMS provides the pieces to solve the... (more)
