internal server error while uploading a file

Question

I want to upload a file using restfull webservice.And when i am exposing this rest service , i am getting 500*(Internal Server Error)*.

resource.java class

   @Path("/resource")
   public class Demo{
   private static final String FOLDER_PATH = "C:/uploaded_license/";    
      @POST
      @Path("/upload")
      @Consumes(MediaType.MULTIPART_FORM_DATA)
      @Produces(MediaType.TEXT_PLAIN)
      public String uploadFile(@FormDataParam("file") InputStream fis,
           @FormDataParam("file") FormDataContentDisposition fdcd) {

         OutputStream outpuStream = null;
         String fileName = fdcd.getFileName();
         System.out.println("File Name: " + fdcd.getFileName());
         String filePath = FOLDER_PATH + fileName;

         try {
             int read = 0;
             byte[] bytes = new byte[1024];
             outpuStream = new FileOutputStream(new File(filePath));
             while ((read = fis.read(bytes)) != -1) {
                 outpuStream.write(bytes, 0, read);
             }
             outpuStream.flush();
             outpuStream.close();
         } catch(IOException iox){
             iox.printStackTrace();
         } finally {
             if(outpuStream != null){
                 try{outpuStream.close();} catch(Exception ex){}
             }
         }
         return "File Upload Successfully !!";
    }
  }

This is the rest service in which *FOLDER_PATH* is the path where the 
uploaded file will saved.

javax.servlet.ServletException: Servlet.init() for servlet jersey-servlet threw exception — parul, May 24 '17 at 04:39
That is not an stack trace. That is a message. Exception happens during the init. The stack trace should tell you where is exception is happening. It should be part of the response in most cases. Verify your web.xml with this:https://stackoverflow.com/questions/22994690/which-init-param-to-use-jersey-config-server-provider-packages-or-javax-ws-rs-a/23041643 — bichito, May 24 '17 at 12:01
Away from computer to verify this but check fully qualified name of the class is the same in web.xml and source file — bichito, May 24 '17 at 15:02
I think the problem is that you are using "file" twice in method parameter annotations. The stack trace points in that direction. If this works, I will post it as an answer — bichito, May 24 '17 at 23:25

I think you need to inti ApplicationContext.xml. Ex. :-

 <servlet>
    <servlet-name>myServlet</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <init-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:ApplicationContext.xml</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
</servlet>
