To put it short: server.xml is for server configuration. web.xml is for configuration per app. Especially web.xml is important, very important for the exam and for J2EE webcomponents dev. in general. Every app should have one. In the links page of this forum, you find some graphical representation of the elements of the web.xml. regards Axel
The web.xml file is a deployment descriptor. It defines how your web components (servlets, JSPs, HTML files, etc) are organized to form a coherent web application. All Servlet 2.3 compliant webapps must have a web.xml file. The server.xml is a configuration file for Apache Tomcat and describes how your web applications (or contexts) are deployed onto Tomcat. This is not a J2EE-specific feature. For another web server, for example, (say JRun) the equivalent file is the local.properties file. -anthony
