| All UI tag templates are written in Freemarker (also a good option for your own views) |
| Commons logging, which the framework uses to support transparently logging to either Log4J or JDK 1.4+ |
| All UI tag templates are written in Freemarker (also a good option for your own views) |
| The default dependency injection container for the framework. |
| The Commons FileUpload package makes it easy to add robust, high-performance, file upload capability to your servlets and web applications. |
| Commons IO is a library of utilities to assist with developing IO functionality. |
| Commons Lang3 is used to simplify usage of common tasks and code shortcuts to to stay DRY |

The library files (*.jar) needs to be copied to your /WEB-INF/lib/ directory. If you need optional functionalities requiring dependencies on optional JARs, those JARs need to be copied to this directory tooIf any Struts 2 Plugins are included, then other JARs may be needed too. For example, the optional Spring Plugin requires the Spring JARs to be present.

The standard web.xml registers a FilterDispatcher to enable framework functionality for your requests. The ContextLoaderListener configures Spring as our dependency injection container. The framework uses Spring internally. (You may wish to use Spring to deploy your own objects too.)
If other packages are being used, like SiteMesh or Spring, then other filters may need to be configured too
