Subject RE: Static class not working under multiple webapps deployment
Date Tue, 15 Oct 2002 13:28:36 GMT
where is this class located? if it is in /common/classes or shared/classes,
that is the correct result.

you will have to copy the .class file to each webapp under its
WEB-INF/classes to get the result that you desire.
