Java.lang.NoSuchMethodError exception

I am trying to upload pdf files to a server. And i; m using the following code block in 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 am doing this to save a pdf file to a pdf file. It works fine on my local host, but when I execute this on the server, I make the following exception:

 exception org.springframework.web.util.NestedServletException: Handler processing failed; nested exception is java.lang.NoSuchMethodError: javax.servlet.http.HttpServletRequest.getServletContext()Ljavax/servlet/ServletContext; org.springframework.web.servlet.DispatcherServlet.doDispatch(DispatcherServlet.java:839) org.springframework.web.servlet.DispatcherServlet.doService(DispatcherServlet.java:719) org.springframework.web.servlet.FrameworkServlet.processRequest(FrameworkServlet.java:644) org.springframework.web.servlet.FrameworkServlet.doPost(FrameworkServlet.java:560) javax.servlet.http.HttpServlet.service(HttpServlet.java:637) javax.servlet.http.HttpServlet.service(HttpServlet.java:717) org.springframework.web.filter.CharacterEncodingFilter.doFilterInternal(CharacterEncodingFilter.java:88) org.springframework.web.filter.OncePerRequestFilter.doFilter(OncePerRequestFilter.java:76) root cause java.lang.NoSuchMethodError: javax.servlet.http.HttpServletRequest.getServletContext()Ljavax/servlet/ServletContext; frontend.controller.EsteemRatingsController.handleFormUpload(EsteemRatingsController.java:113) sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:57) sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) java.lang.reflect.Method.invoke(Method.java:601) org.springframework.web.bind.annotation.support.HandlerMethodInvoker.invokeHandlerMethod(HandlerMethodInvoker.java:176) org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter.invokeHandlerMethod(AnnotationMethodHandlerAdapter.java:436) org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter.handle(AnnotationMethodHandlerAdapter.java:424) org.springframework.web.servlet.DispatcherServlet.doDispatch(DispatcherServlet.java:790) org.springframework.web.servlet.DispatcherServlet.doService(DispatcherServlet.java:719) org.springframework.web.servlet.FrameworkServlet.processRequest(FrameworkServlet.java:644) org.springframework.web.servlet.FrameworkServlet.doPost(FrameworkServlet.java:560) javax.servlet.http.HttpServlet.service(HttpServlet.java:637) javax.servlet.http.HttpServlet.service(HttpServlet.java:717) org.springframework.web.filter.CharacterEncodingFilter.doFilterInternal(CharacterEncodingFilter.java:88) org.springframework.web.filter.OncePerRequestFilter.doFilter(OncePerRequestFilter.java:76)

If I delete the lines that are indicated above in the controller class, it works (from the source without downloading PDF files). Can anyone help me with this?

This request.getServletContext() method was introduced in servlet 3.0. Make sure your container / library supports this version.

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

it can be auto-updated: 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); ...
