Java servlet rest服务的500-servlet.init（）引发异常

我已经包括了jar文件jersey-archive-1.18、jersey-multipart.jar和mimepull.jar 这是我在com.mkyong.rest包中的类文件（UploadFileService.java）

 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();
            }
    }

    }

这是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>

将以下代码添加到相应位置的.project文件中

您正在使用哪个应用程序服务器？看起来您正在使用tomcat，它是一个web容器，而不是一个完整的应用程序服务器。它不支持CDI开箱即用。是的，我使用的是ApacheTomcat服务器。实际上在这之前，我写过一个rest服务，它可以将文件从一个驱动器传输到另一个驱动器，并且工作正常。是否存在依赖关系或配置问题？可能是stacktrace中存在inject.错误。如果你把这个建立在TomEE的基础上会怎么样？我还没有在TomEE上试过。好的，我给我试试这个。
