<p>Designers and developers of applications that run with or under WebSphere Application Server - Express, such as servlets and JSP files, and their supporting classes, may find it useful to use the same facility for generating messages that WebSphere Application Server - Express itself uses, JRas.</p>
|
||
|
|
|
||
|
|
<p>This approach has advantages over simply adding System.out.println() statements to your code:</p>
|
||
|
|
|
||
|
|
<ul>
|
||
|
|
<li>Your messages appear in the WebSphere Application Server - Express standard message format with additional data, such as a date and time stamp, added automatically.</li>
|
||
|
|
<li>You can more easily correlate problems and events in your own application to problems and events associated with WebSphere Application Server - Express components.</li>
|
||
|
|
<li>You can take advantage of the WebSphere Application Server - Express log file management features.</li>
|
||
|
|
<!--<li>You can view your messages with the WebSphere Application Server - Express user-friendly Log Analyzer tool.</li>-->
|
||
|
|
</ul>
|
||
|
|
|

|
