500-servlet球衣剩余服务的servlet.init（）抛出异常

Question

I have included jar files jersey-archive-1.18 , jersey-multipart.jar and mimepull.jar This is my class file (UploadFileService.java) inside the package com.mkyong.rest

 package com.mkyong.rest;

    import javax.ws.rs.Path;
    //import javax.ws.rs.Produces;
    import javax.ws.rs.core.MediaType;

    import java.io.File;
    import java.io.FileOutputStream;
    import java.io.IOException;
    import java.io.InputStream;
    import java.io.OutputStream;

    import javax.ws.rs.Consumes;


    import javax.ws.rs.POST;
    import javax.ws.rs.core.Response;
    import com.sun.jersey.core.header.FormDataContentDisposition;
    import com.sun.jersey.multipart.FormDataParam;


    @Path("/file")
    public class UploadFileService {

    @POST
    @Path("/upload")
    @Consumes(MediaType.MULTIPART_FORM_DATA)
    public Response uploadFile( @FormDataParam("file") InputStream uploadedInputStream,
        @FormDataParam("file") FormDataContentDisposition fileDetail) {

        System.out.println("ok");
       /* String uploadedFileLocation = "d://upload/" + fileDetail.getFileName();*/
        String uploadedFileLocation = "d://upload/" + "abc.pdf";

            writeToFile(uploadedInputStream, uploadedFileLocation);

            String output = "File uploaded to : " + uploadedFileLocation;

            return Response.status(200).entity(output).build();

            }

    private void writeToFile(InputStream uploadedInputStream,
                                    String uploadedFileLocation) {
        try {
                OutputStream out = new FileOutputStream(new File(
                uploadedFileLocation));
                int read = 0;
                byte[] bytes = new byte[1024];

                out = new FileOutputStream(new File(uploadedFileLocation));
                while ((read = uploadedInputStream.read(bytes)) != -1) 
                {
                  out.write(bytes, 0, read);
                }
                out.flush();
                out.close();
            } catch (IOException e) {

               e.printStackTrace();
            }
    }

    }

This Upload.html

<form action="rest/file/upload" method="post" enctype="multipart/form-data" style="margin-top:20px;margin-bottom:30px;width:100%;height:60px;">

    <input type="file" name="file"  class="btn btn-info btn-xm" style="float:left;margin-right:6px;margin-bottom:10px;"/>
    <p>Target Upload Path : <input type="text" name="path" /></p>
    <input type="submit" class="btn btn-warning" value="Upload" style="float:left;" id="Map" value="Map" onclick="showImg()"/>

    <img src="image/loading.gif" id="map_img" style="display: none;"/>
    <span id="countdown" class="btn btn-danger" style="float:right;"></span>

 </form>

And this is the servlet mapping in web.xml config

<display-name>RESTfulWS</display-name>   
<servlet> 
<servlet-name>Jersey REST Service</servlet-name> 
<servlet-class>com.sun.jersey.spi.container.servlet.UploadFileService</servlet-class> 
<init-param> 
<param-name>com.sun.jersey.config.property.packages</param-name> 
<param-value>com.mkyong.rest</param-value> 
</init-param> 

<load-on-startup>1</load-on-startup> 
</servlet> 
<servlet-mapping> 
<servlet-name>Jersey REST Service</servlet-name> 
<url-pattern>/rest/*</url-pattern> 
</servlet-mapping>

Can you please tell me where I am wrong, I am getting the following error:
