[former_member600332]

Hi, Please help to resolve my error. I am using crystal report viewer on eclipse. I can able to see that data in report but when trying to use page navigation, search or any action which is present in toolbar getting below error. I am using struts2 with crystal report viewers jar in eclipse.

The viewer is unable to connect with the CrystalReportViewerServlet that handles asynchronous requests.
Please ensure that the Servlet and Servlet-Mapping have been properly declared in the application's web.xml file.

Below I have mention my web.xml contents please have a look:
