Solved my own problem. Helps when you get access to decent document in the form of Ceci's book :) Would like to make a friendly suggestion for the basic documentation to be extended. But regardless for those out there who don't plan to buy the book.
There are 3 params you can enter for the ASYNC appender: * BufferSize - which defaults to 128 messages * LocationInfo - boolean deafults to false * Threshold - no idea what this does So insert the LocatioInfo param tag i.e. <appender name="ASYNC" class="org.apache.log4j.AsyncAppender"> <param name="BufferSize" value="256"/> <param name="LocationInfo" value="true"/> <appender-ref ref="TEMP"/> <appender-ref ref="CONSOLE"/> </appender> I added the BufferSize for fun. Pretty easy when you find the documentation. Refer to the javadoc on the AsyncAppender which shows the methods for the setLocationInfo and setBufferSize: http://jakarta.apache.org/log4j/docs/api/org/apache/log4j/AsyncAppender.html Terence ----- Original Message ----- From: "Terence Ingram" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Tuesday, June 17, 2003 10:33 AM Subject: ASYNC Appender not printing line or class information > I have searched the archives for a resolution to this problem and the only > reference is: > http://www.mail-archive.com/[EMAIL PROTECTED]/msg06540.html > which does not appear to have a resolution. > > My problem.
