Subject HTMLLayout.java Patch
Date Mon, 03 Oct 2005 21:27:53 GMT
Patch for HTMLLayout.java to allow the user of the logger to turn the 
html header/footer off if needed.

I'm using log4j to output some html but I'm doing this within an 
existing webpage.  Therefore, I don't need/want the html 
header/footer that the logger normally prints out.

Added the member var shouldWriteHtmlHeaderAndFooter and the 
appropriate if statements to make the desired effect.  Also added an 
assessor and setter for shouldWriteHtmlHeaderAndFooter.


Thanx for the awesome logging lib.
