I wan't to generate a Barcode which is type of GS1 databar expanded. I'm searched in google and didn't found realy working results. I discover that ZXing gives the possibility to generate different barcodes. I wrote an small code and i can generate barcode for ean128.

package de..barcodee128;
import java.io.File;
import java.io.FileOutputStream;
import com.google.zxing.BarcodeFormat;
import com.google.zxing.WriterException;
import com.google.zxing.client.j2se.MatrixToImageWriter;
import com.google.zxing.common.BitMatrix;
import com.google.zxing.oned.Code128Writer;
import com.google.zxing.oned.Code39Writer;
import com.google.zxing.oned.OneDimensionalCodeWriter;
import com.google.zxing.oned.rss.expanded.decoders.AbstractExpandedDecoder;

public class barcode128 {
    public static void main(String[] args) {

           int width = 440; 
           int height = 48;


           BitMatrix bitMatrix;
        try {
            bitMatrix = new Code128Writer().encode("10400550006232515201231",BarcodeFormat.RSS_EXPANDED,width,height,null);
            MatrixToImageWriter.writeToStream(bitMatrix, "png", new FileOutputStream(new File("C:\\Users\\fecub\\Desktop\\zxing_barcode.png")));
        } catch (WriterException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (Exception e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } 

    }

}

But my question is how to modify this code that gives me to possibility to create GS1 databar expanded barcodes? any idea??

GS1 Databar Expanded is just the replacement name for what was the RSS Expanded symbology. These are read by the project, but not written, no.

(*) The RSS family of barcode symbologies were renamed to avoid clashing with the more common use of RSS as an acronym for Really Simple Syndication.
