Here is a Struts 2 action that can be called to reload your Struts 2 resource properties. In the case below, my resource properties are "/classes/struts/resources.properties" and "/classes/struts/resources_pt.properties". Therefore, the resources bundle name is "struts/resources". I make changes to my resources properties file, and then I call the following action, and the resources are dynamically reloaded.
