The following code gives the error

String absolutePath = request.getServletContext().getRealPath(item.getName());



Apr 10, 2013 4:25:39 PM org.apache.catalina.core.StandardWrapperValve invoke

Did you perchance copy the servlet API jar into WEB-INF/lib? If so, remove it.

java.lang.NoSuchMethodError: javax.servlet.http.HttpServletRequest.getServletContext()Ljavax/servlet/ServletContext;

You can not get context from request object. Use getServletConfig to get context (or simply use getServeletContext() method)

You can, actually, since version 3.0 of the Servlet specification (->click).

I am sorry, You are right Jelle Klap. Its possible in 3.0.

Hi Syed Ali, could you check your jar file servlet 3.0 version?

Which likely means that the compile time and run time environments use different level of the Servlets API.
 
It is sorta covered in the JavaRanch Style Guide.
