I have EAR file with few web application that have to share libraries (jar's). For example, using WebLogic I can just put them (jar's) in APP-INF/lib directory and all webapps can use them. What about JBoss 4.0.4 or 4.0.5? Is any "special" default directory targeted to shared libraries? Or I have to reference every shared jar in every webapps manifest file?
