The Struts 2 framework produces warnings if no action is found in the runtime configuration while rendering the JSP page when the application is configured to run in the struts.devMode. It helps the developer to resolve inappropriate mapping of the actions in the Struts tags. However, the action mapping not always inferred statically but at runtime. So, the tags should be able to find mappings from the attributes in the value stack. But the struts tags is only executed in the action context that won't be available when you redirect from the error page. Make sure you have correct URL that is mapped to the Struts action when redirected to it.
