Using the Java Component, certain Code 39 characters, such as the underscore, do not scan.


We are using LinearBarcode.jar in oracle and I noticed that when barcode is generated for value example A_B, it reads as AB when scanned and the underscore '_' is ignored. Please help

Operating System: LINUX

Application: Oracle EBS

The standard Code 39 character set does not include the underscore. It is part of Extended Code 39. To encode the underscore, set your symbology to Extended Code 39. Using the Symbology chart for Java, there are two options:

image

(1) Set the type:
barcode.barType = barcode.CODE39EXT;

In your example:
barcode.barType (BarcodeObject,barcode.CODE39EXT)

(2) Set the symbology id:
barcode.setSymbologyID = (1);

In your example:
barcode.setSymbologyID (BarcodeObject,1)


Set the scanner to read Extended Code 39/Full ASCII.

After setting scanner to full ASCII, the scanner identified underscore. Thanks for your solution

In your case, you would use barcode.setSymbologyID (BarcodeObject,1);

Then you will want to make sure your scanner is set to full ASCII or else it will display the _ as %O.

Do you mean set it as barcode.setSymbologyID (BarcodeObject,1);

Because if I set as barcode.setSymbologyID = (1); , it throws some error when I compile

After I have done the above change to barcode.setSymbologyID (BarcodeObject,1); I can see the %O coming into picture when scanned.

For example if value is A_B, it is read as A%OB

Set the Symbology to 1 (which is the Code 39 Extended)

barcode.setSymbologyID = (1);

Below is my code. Can you please help in placeing the above . i ma not a java expert

==========
BEGIN
imageFile := srw.create_temporary_filename();
-- -------------------------------------------------------------------------
-- Create the barcode object
-- -------------------------------------------------------------------------
BarcodeObject := Barcode.new();
-- -------------------------------------------------------------------------
-- Set the symbology
-- -------------------------------------------------------------------------
Barcode.setSymbologyID(BarcodeObject, Barcode.CODE39EXT);

barcode.setShowText(BarcodeObject,FALSE);
barcode.setCheckCharacterInText(BarcodeObject,FALSE);
barcode.setCheckCharacter(BarcodeObject,FALSE);
barcode.setTopMarginCM(BarcodeObject,0);
--barcode.setXDimensionCM(BarcodeObject,.10);
--barcode.setBarHeightCM(BarcodeObject,.10);
-- -------------------------------------------------------------------------
-- set the data to encode
-- -------------------------------------------------------------------------
Barcode.setDataToEncode(BarcodeObject, to_char(:resource_code));
-- -------------------------------------------------------------------------
-- Create the jpeg
-- -------------------------------------------------------------------------
BarcodeEncoderObject := BarcodeEncoder.new(BarcodeObject, 'JPEG',ImageFile);

-- -------------------------------------------------------------------------
-- If, for some reason, the barcode is not created, return null
-- otherwise, return the name of the barcode image jpeg that was created
-- -------------------------------------------------------------------------

IF ORA_JAVA.IS_NULL(BarcodeEncoderObject) then
return(NULL);
ELSE
return(ImageFile);
END IF;
END;
