如何退回多部分MIME類型的消息

Question

客戶端代碼....

HttpPost httpPost = new HttpPost(); 
MultipartEntity multipartEntity = new MultipartEntity(); 
FormBodyPart xmlPart = new FormBodyPart("soap-req", new StringBody(returnXml(), "text/xml", Charset.forName("UTF-8"))); 
multipartEntity.addPart(xmlPart); 

FormBodyPart attachPart = new FormBodyPart("taxinvoice", new FileBody(attachPartIS)); 
attachPart.addField("Content-ID", "<attachPart>"); 
multipartEntity.addPart(attachPart); 

httpPost.setEntity(multipartEntity); 
httpPost.addHeader("Soapaction", "\"\""); 
httpPost.addHeader("Accept", "text/xml, multipart/related, text/html, image/gif, image/jpeg, *; q=.2, */*; q=.2"); 

DefaultHttpClient httpclient = new DefaultHttpClient(); 
HttpResponse response = httpclient.execute(soapPost); 

客戶端發送多部分MIME消息服務器

我想收到clientmessage並返回多部分MIME類型的消息

我試圖下面

@Path("/Contact") 
@Consumes("multipart/related") 
public class ContactService{ 
    @POST 
    @Produces({"text/xml","application/octet-stream"}) 
    public Response returnMultiPart(InputStream in) throws Exception{ 
     ..... 

     return Response.ok(multipartEntity, MediaType.MULTIPART_FORM_DATA).build(); 
    } 
} 

錯誤消息是A message body writer for Java class org.apac....and MIME media type multipart/form-data was not found

Mapped exception to response: 500 (Internal Server Error)

PLZ幫我

我只是想在我的web服務返回multipart_MIME類型的消息給客戶端。

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

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

     String uploadedFileLocation = "d://uploaded/" + fileDetail.getFileName(); 

     // save it 
     writeToFile(uploadedInputStream, uploadedFileLocation); 

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

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

    } 

    // save uploaded file to new location 
    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(); 
     } 

    } 

}
