I'm a newer java/Java EE application programmer :
The aim of my question that i found a tutorial or a refcard talking about integration of struts 2, spring 3, hibernate 3 under a Java EE project( the database doesn't matter and the eclipse version too) wich explain the role of each configuration file( such as web.xml, application-context.xml, struts.xml) and what you have to put inside. i hope that it gives the process that porsuit a request from the User Interface to the data layer and the role of the configuration files.
