What is the configuration files used in Struts?
The Struts framework uses one or more configuration files to load and create required application-specific components. These configuration files allow the components to be declaratively specified, rather than having hardcoded behavior and information. This can give you the flexibility to provide your own extensions. Based on XML format, configuration files can be validated against Struts DTD.
We can configure with the help of few important configuration files like struts.xml, web.xml,strutsconfig.xml and struts.properties
