The IBM(R) JRas toolkit is a set of Java(TM) packages that enables developers to incorporate message logging and trace facilities into Java applications. Although JRas is a standalone product, it has been customized for use with the Standard, Advanced, and Enterprise (Component Broker) Editions of WebSphere(TM) Application Server. The WebSphere implementation of JRas integrates with the WebSphere run-time environment and system-management utilities (for instance, Advanced Edition's Administrative Console and Component Broker's System Manager). This document discusses the WebSphere implementation of JRas and using it to write WebSphere applications that log and manage application-specific messages and trace. Use of the non-WebSphere implementation of JRas is not discussed in this document.
