[Opensource] xerces update option

[larry hamel]

hi,

Regarding the problem with old and new versions of Xerces, where there is an old version in tomcat 4.0.x, and a new version in expresso 5.x:

I recently hit a problem with this on a production server, and found that tomcat 4.0.x seems to be able to do fine with a wholesale replacement of Xerces in favor of the new files.  In particular, the following replacement worked:

in tomcat 4.0.x directory common/lib/

xerces.jar (remove)
xercesImpl.jar (add)
xmlParserAPIs.jar (add)

YMMV,

Larry
