Hi, Unfortunately, I usually have to resort to more basic techniques like jar tvf some.jar | grep somePackage for example jar tvf weblogic.jar | grep log4j
I've found many an unexpected duplicate class that way, especially for the XML APIs. ;( Yoav Shapira Millennium ChemInformatics >-----Original Message----- >From: Mitch Christensen [mailto:mitch.christensen@;informatixinc.com] >Sent: Wednesday, October 30, 2002 11:49 AM >To: Log4J Users List >Subject: RE: JRun4, WebLogic 7.0 & Log4J bufferedIO exception > >I think this may in fact be the case, but there doesn't appear to be >another >log4j*.jar anywhere on my disk. > >Does anyone have any toos/techniques for identifying where a particular >class (in this case org.apache.log4j.RollingFileAppender) loads from?
