Custom 404 error page not working with Struts 2

Question

I am converting a JSP/Servlet dynamic web project to Struts 2 and the custom error pages (that previously worked with the JSP/Servlet version) have stopped working.

When

Answer 1

Instead of custom error page create a custom error action that returns a result to a custom error page.

struts.xml:

  /404.jsp
  /500.jsp
 

ErrorAction:

public class ErrorAction extends ActionSupport {

  private Integer statusCode;
  //getter and setter

  @Override
  public String execute() {
    if (stausCode != null)
    switch (statusCode){
      case 404:
        return "404";
      case 500:
        return "500";
    }
  }
}

web.xml:

    404
    /error_code.jsp



    500
    /error_code.jsp

error_code.jsp:

<% 
 Integer statusCode = (Integer) request
                       .getAttribute("javax.servlet.error.status_code");

 response.sendRedirect(pageContext.getServletContext().getContextPath()
                       +"/error?statusCode="+statusCode ); 
%>
