Suppose I have a JavaScript file that sends an AJAX request: $("button").click(function(){ $.ajax({url: "myTestUrl.do", success: function(result){ //do something with result }); }); and my struts-config.xml file looks like this: <?xml version="1.0" encoding="ISO-8859-1"?> <!DOCTYPE struts-config PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 1.1//EN" "http://jakarta.apache.org/struts
