IBM's Method Scheduler for J2EE, Servlets and JSP

Method Scheduler for JavaTM (MS4J) is a robust scheduler component that allows developers to execute methods on Java objects asynchronously and/or repeatedly. It is easy to learn and simple to use.

Asynchronous data flows have not been emphasized in J2EE. Servlets and Java Server Pages (JSPs) are usually multithreaded, but they remain fundamentally synchronous. The same is true for most Java data adapters; they are frequently multithreaded, yet synchronous.

At the same time, as the general complexity of a Web application increases, asynchronous facilities become a necessity. They are necessary, for example, for keeping memory caches fresh, for scheduling repetitive method invocations in general, or for increasing page response times by performing certain input/output (I/O) operations (such as database updates) asynchronously, in parallel with or after page delivery to the client.

Method Scheduler for Java is designed to partially fill these gaps. It does not require modification of the classes and methods to be invoked. This feature helps when there is a lot of code that is already written. Method Scheduler for Java also uses configurable thread pools, which can prevent system slowdowns during periods of high loads.
