Webobjects DST fix

Does anyone know which jar the DST fix is in?  On my local system, I  
attempted to find the correct jars by using:
locate .jar | grep WebObjects | xargs ls -l

and looking for webobjects jars that were modified recently; I found  
these:
/Library/WebObjects/lib/JavaFoundation.jar
/Library/WebObjects/lib/JavaWebObjects.jar
/System/Library/Frameworks/JavaWebObjects.framework/Resources/Java/ 
javawebobjects.jar

I've got webobjects running on a linux system; I copied over these  
jars, but my times are still not correct under the new improved  
daylight savings time.

Any suggestions?  Did I miss something obvious?
