                     is exactly the same as the defaultStack, except that it
                     includes one extra interceptor before the prepare interceptor:
                     the params interceptor.

                     This is useful for when you wish to apply parameters directly
                     to an object that you wish to load externally (such as a DAO
                     or database or service layer), but can't load that object
                     until at least the ID parameter has been loaded. By loading
                     the parameters twice, you can retrieve the object in the
                     prepare() method, allowing the second params interceptor to
                     apply the values on the object. -->

                <!-- A complete stack with all the common interceptors in place.
                     Generally, this stack should be the one you use, though it
                     may do more than you need. Also, the ordering can be
                     switched around (ex: if you wish to have your servlet-related
                     objects applied before prepare() is called, you'd need to move
                     servletConfig interceptor up.

                     This stack also excludes from the normal validation and workflow
                     the method names input, back, and cancel. These typically are
                     associated with requests that should not be validated.

This file defines all of the default bundled results and interceptors and many interceptor stacks which you can use either as-is or as a basis for your own application-specific interceptor stacks.

Notice the name of the package is “struts-default”
