راجع هذا السطر

UploadClass.java:112

هذا هو السطر 

at UploadClass.b1_action(UploadClass.java:112)

وانا لم افهم ما الخطأ  فية  ..  حيث  b1_action انها اسم الدالة المستخدمة (methoed)

ما المكتوب في هذا السطر؟

هدذ هو كود ال Method

        String imagesFolder = "C:\\Upload_Image\\";

                      File myFile = new File(imagesFolder);

                      if ( !myFile.exists() )   {  myFile.mkdir(); }

                      String newImageFile    = imagesFolder +  this.getCurrentIMPORTS()+".png";

                      try {

                          InputStream inputStream         = getFile_IMP().getInputStream();

                          FileOutputStream outputStram    = new FileOutputStream(newImageFile);


                          byte[] buffer = new byte[8192];

                          int bytesRead = 0;

                         

                          while ((bytesRead = inputStream.read(buffer)) != -1) {

                              outputStram.write(buffer, 0, bytesRead);

                          }

                          outputStram.flush();

                          outputStram.close();

                          inputStream.close();

                          getFile_IMP().dispose();

                         

                      } catch (FileNotFoundException fnfe) {

                          // TODO: Add catch code

                          fnfe.printStackTrace();

                      } catch (IOException ioe) {

                          // TODO: Add catch code

                          ioe.printStackTrace();

                      } 
        return null;
    }

وهذا ايضا كود 

    public String getCurrentIMPORTS() {

        BindingContainer bindings = BindingContext.getCurrent().getCurrentBindingsEntry();

        AttributeBinding attr = (AttributeBinding)bindings.getControlBinding("ImoCode1"); 

        return  attr.getInputValue().toString().trim();

      }

ضع السطر فقط

ضع السطر فقط

اي سطر تقصد اسف ولاكني لم افهمك 

هذا هو كل الكود المكتب داخل زر  ال upload
