Please tell me use of Application.xml and weblogic.xml in a java web project. For what are they configured for ? I have developed few web projects and deployed in tomcat and never used Application.xml. BUt I have seen few projects deployed on Weblogic.xml, which have weblogic.xml and Application.xml. Is it madatory to configure those two files if we were to deploy an application in Weblogic server ? Isn't web.xml alone suffice ? Many thanks in advance!!!
