multipart/form-data로 j2me의 서버에 이미지를 업로드하는 방법은 무엇입니까?

Question

j2me를 처음 사용하면서 j2me.It에서 모바일 이미지를 업로드하려고하는데 서버 쪽에서 예외가 표시됩니다.

제발 해결 방법을 제안하십시오.

From J2me 코드를 사용하여 서버에 이미지를 업로드하고 있습니다.

HttpConnection conn = null; 
    OutputStream os = null; 
    // InputStream is = null; 

    try 
    { 
     System.out.println("url:" + serverurl); 
     conn = (HttpConnection)Connector.open(serverurl); 
     conn.setRequestMethod(HttpConnection.POST); 

     // String postData = ""; 

     InputStream imgIs = getClass().getResourceAsStream(FILE); 
     byte []imgData = new byte[imgIs.available()]; 
     imgIs.read(imgData); 

     conn.setRequestProperty("Content-Type", "multipart/form-data; boundary=---------------------------4664151417711"); 

     os = conn.openOutputStream(); 
     // os.write(message1.getBytes()); 
    // For First Image uploading 

    String message1 = ""; 
     message1 += "-----------------------------4664151417711" + CrLf; 
    message1 += "Content-Disposition: form-data; name=\"photo\"; 
        filename=\"" + FILE + "\"" + CrLf; 
    message1 += "Content-Type: image/jpeg" + CrLf; message1 += CrLf; 

      os.write(message1.getBytes()); 


     // SEND THE IMAGE 
     int index = 0; 
     int size = 1024; 
     do{ 
      System.out.println("write:" + index); 
      if((index+size)>imgData.length){ 
       size = imgData.length - index; 
      } 
      os.write(imgData, index, size); 
      index+=size; 
      progress(imgData.length, index); // update the progress bar. 

     }while(index<imgData.length); 

     System.out.println("DONE"); 

    } 
    catch(Exception e) 
    { 
     e.printStackTrace(); 
    }finally 
    { 
     System.out.println("Close connection"); 
     try 
     { 
      //os.close(); 
     } 
     catch(Exception e){} 
     try 
     { 
      // is.close(); 
     } 
     catch(Exception e){} 
     try 
     { 
      // conn.close();    
     } 
     catch(Exception e){} 
    } 

on serside we use the code: 
    System.out.println(".............Images..122223...Images..."); 
FileItemFactory factory = new DiskFileItemFactory(); 
ServletFileUpload upload = new ServletFileUpload(factory); 
System.out.println(".............Images...11111..test..."+upload); 
boolean isMultipart = ServletFileUpload.isMultipartContent(request); 
    System.out.println(".............Images...11111..test..."+isMultipart); 

if(isMultipart) 
{ 
     System.out.println(".............Images...11111..Images..Images...."); 
     List items = upload.parseRequest(request); 
     System.out.println(".............Images.33333....Images..Images...."); 

      Iterator iterator = items.iterator(); 
      while(iterator.hasNext()) 
      { 
       String fieldName = ""; 
        String fieldValue=""; 
        String fileName = ""; 
        FileItem fileItem=(FileItem)iterator.next(); 
        System.out.println(fileItem.isFormField()); 
    if (fileItem.isFormField()) 
    { 
     fieldName = fileItem.getFieldName(); 
     fieldValue = fileItem.getString("UTF-8").trim(); 

     if(fieldName.equals("photo")) 
     { 
      if(fieldValue!=null && fieldValue!="") 
      { 
        photo = fieldValue; 
        System.out.println(photo); 
      } 
     } 
    }   
    else 

    try 
    { 
     if(fileItem != null) 
     { 
      fileName = applicationNumber+"_"+fileItem.getName(); 
      fieldName = fileItem.getFieldName(); 
      System.out.println("applicationNumber="+fileName); 
     } 
     if(fieldName.equals("photo")) 
     {  
      String x=fileName; 
      if(x.indexOf("/")!=-1) 
      { 
       uploadStr = x.substring(0,x.lastIndexOf("/")); 
       UploadFile = x.substring(x.lastIndexOf("/")+1,x.length()); 
      } 
      long sizeInBytes = fileItem.getSize(); 
      String applicationURL = "C:/Program Files/ 
       Apache Software Foundation/Tomcat 6.0/webapps/apply_smart/applications"; 
    StringTokenizer stringTokenizer = new StringTokenizer(UploadFile,"\\"); 
       int count=stringTokenizer.countTokens(); 
       for(int i=1;i<=count;i++) 
       { 
          String token=stringTokenizer.nextToken(); 
          if(i==count) 
          { 
           audioFileName=token; 
          } 
        } 
        applicationURL = applicationURL; 
        System.out.println("Path="+applicationURL); 
        String[] filePath = fileName.split("/"); 
    uploadedFile = new File(applicationURL+"/"+filePath[filePath.length - 1]); 
        long size=uploadedFile.length(); 
        if(size>=11264) 
        { 
         } 
            try 
            { 
         fileItem.write(uploadedFile); 
         path = applicationURL.replaceAll 
    ("C:/ProgramFiles/ApacheSoftwareFoundation /Tomcat 6.0/ webapps/apply_smart/", ""); 
        path= path + "/"+ filePath[filePath.length - 1]; 
         System.out.println("path::::::"+path);     
       } 
       catch (java.lang.Exception e) 
       { 
        out.println(e); 
       } 
          } 
      }//else 
    } 
    catch(Exception exe) 
    { 
    out.println(exe); 
    break; 
    }  
        } 

예외를 해결하고 이미지를 서버에 보내는 방법을 제안 해주세요.

미리 감사드립니다. .

미안 내가 잘못이 무엇인지 확인하기 위해 코드를 통해 확인하는 시간이 없어,하지만 난 그것을 작동하지 않는, 내가 그 코드를 사용, 이전에이 solution by Jason Woods
