내가 파일을 전달하고있다 :이 내가 얻고 무엇 그러나

public BufferedImage readDicomFile(File dicomFile) { 

    ImageReader reader = (ImageReader) ImageIO.getImageReadersByFormatName("DICOM").next(); 
    BufferedImage tempImage = null; 
    try { 
     if (!dicomFile.exists()) {   
      return null; 
     } 
     ImageIO.scanForPlugins(); 
     tempImage = ImageIO.read(dicomFile);    
     DicomObject obj = new DicomInputStream(dicomFile).readDicomObject(); 
     String overlayData = obj.getString(1610625024); 
     if ((overlayData != null) && (overlayData.length() > 0)) { 
      tempImage = combineImages(tempImage, 
        OverlayUtils.extractOverlay(obj, 1610625024, reader, 
          "FFFFFF")); 
     } 
    } catch (IOException ex) { 
     ex.printStackTrace(); 
    } catch (Exception e) { 
     e.printStackTrace(); 
    } 
    return tempImage; 
} 

입니다 특정 경로를 가리키는 "c : \ temp2 \ testing.dcm"개체입니다. Dicom 파일을 읽으려고하는 줄에 올 때 위의 오류가 발생합니다.

도와 주시겠습니까?

살람 와엘는 문제에 대한

근본 원인은 자동으로

이것이 의미/디 등록 네이티브 라이브러리를 등록 처리 할 수있는 서블릿 컨테이너 (바람둥이, ..) 때 dcm4che로드 ImageIO에서 DICOM 플러그인하는 dcm4che DICOM 리더/라이터 코드를 실행할 때마다 플러그인을 다시 검사해야하는 다른 웹 애플리케이션 (서블릿)에서 플러그인을 사용하려면 플러그인을 소유 한 네이티브 라이브러리를 사용합니다.

내가 내가 "ImageIO.scanForPlugins을()"를 사용하고 일 미래

 try{ 
ImageIO.scanForPlugins() 
    //Dicom code 
     } 
    catch { 
    //exceptions 
    } 
    finally { 
       try { 
        // De-register any locally registered IIO plugins. Relies on 
        // each web app having its own context class loader. 
        final IIORegistry registry = IIORegistry.getDefaultInstance(); 
        final LocalFilter localFilter = new LocalFilter(Thread.currentThread().getContextClassLoader()); 

        // scanForPlugins uses context class loader 
        Iterator<Class<?>> categories = registry.getCategories(); 

        while (categories.hasNext()) { 
         Class<?> category = categories.next(); 
         Iterator<?> providers = registry.getServiceProviders(category, localFilter, false); 

         // Copy the providers, as de-registering while iterating 
         // over providers will lead to 
         // ConcurrentModificationExceptions. 
         List<Object> providersCopy = new ArrayList<Object>(); 
         while (providers.hasNext()) { 
          providersCopy.add(providers.next()); 
         } 

         for (Object provider : providersCopy) { 
          registry.deregisterServiceProvider(provider); 
          log.debug(String.format("Unregistered locally installed provider class: %s",provider.getClass())); 
         } 
        } 
       } catch (Exception ex) { 
        _logger.error("Exception occured while de-registering locally registered IIO plugins", ex); 
       }
