http://struts.apache.org/2.1.6/docs/struts-defaultxml.html Search for 'workflow' and you will find this: <interceptor name="workflow" class="com.opensymphony.xwork2.interceptor.DefaultWorkflowInterceptor"/> This tells you the class="com.opensymphony.xwork2.interceptor.DefaultWorkflowInterceptor" so you can then read the javadocs: http://struts.apache.org/2.1.6/struts2-core/apidocs/com/opensymphony/xwork2/interceptor/DefaultWorkflowInterceptor.html In a nutshell the workflow interceptor will cause the 'input' result to be returned if there has been any errors.
