This week's book giveaways are in the Refactoring and Agile forums. We're giving away four copies each of Re-engineering Legacy Software and Docker in Action and have the authors on-line! See this thread and this one for details.
I just noticed the topic of Application Modules: "A new feature of Struts 1.1 is the concept of application modules. Application modules allow a single Struts application to be split into multiple modules, each with its own Struts configuration file, JSP pages, Actions, and so on."
I went over few struts books already, I don't recall any of them goes into detail about Application Modules. How often is it done in real world applicatoin development?
