Subject Re: $CATALINA_HOME/common/lib or WEB-INF/lib
Date Thu, 28 Jun 2007 07:42:03 GMT
Mentioned webapps are strictly related. In fact they are part of one 
large system. What is the best way to add make library/libraries 
available to all application? Put it in $CATALINA_HOME/common/lib or is 
there better way to do that?
