Exception java.lang.NoSuchMethodError

Question

I'm trying to upload pdf files in the server. And i;m using the following block of code into the controller:

 @RequestMapping(value = /submit, method = RequestMethod.POST)
 public String upload(UploadItem uploadItem, BindingResult result, HttpServletRequest request, HttpSession session) {

   //some code here

   String name = request.getServletContext().getRealPath("/pdf/" + filename);
   File dest = new File(name);
   try {
        file.transferTo(dest);
   }catch(Exception e){
        System.err.println(e);
   }

   return "redirect:/details";

I'm doing this in order to store the pdf's into the pdf file. In my localhost works fine but when i'm executing this on the server i'm taking the following exception:

exception

If i remove the lines that provide above in the controller class is working(ofcource without uploading the pdf's). Can anyone help me with this?

Answer 1

That method request.getServletContext() was introduced in servlet 3.0. Make sure your container/library support that version.

edit: tomcat 6 only have servlet 2.5, see http://tomcat.apache.org/whichversion.html

it can be autowired: ServletContext and Spring MVC

public class Xxxx{
    @Autowired
    ServletContext context;

    @RequestMapping(value = "/submit", method = RequestMethod.POST)
    public String upload(UploadItem uploadItem, BindingResult result, HttpServletRequest request, HttpSession session) {

       //some code here

       String name = context.getRealPath("/pdf/" + filename);
...
