Programming with the JRas framework
Use the JRas extensions to incorporate message logging and diagnostic trace into WebSphere® Application Server applications.
Before you begin

About this task
Note: This topic references one or more of the application server log files. As a
recommended alternative, you can configure the server to use the High Performance Extensible Logging
(HPEL) log and trace infrastructure instead of using SystemOut.log ,
SystemErr.log, trace.log, and
activity.log files on distributed and IBM®
i systems. You can also use HPEL in conjunction with your native z/OS® logging facilities. If you are using HPEL, you can access all of your log and trace
information using the LogViewer command-line tool from your server profile bin directory. See the
information about using HPEL to troubleshoot applications for more information on using HPEL.
Procedure
- Retrieve a reference to the JRas manager.
- Retrieve message and trace loggers by using methods on the returned manager.
- Call the appropriate methods on the returned message and trace loggers to create message and trace entries, as appropriate.
