条形码不使用iText以PDF格式显示

Question

我正在使用iText动态生成PDF文档.现在我正在尝试在此PDF中动态创建条形码.Adobe Live Cycle内置条形码功能.您只需拖动页面上的条形码文本框即可创建它.

问题:
我将条形码字段放在PDF中.然后将数字传递给JSP页面中的条形码字段.但只有数字出现.条形码行永远不会显示

数字20099002在PDF文档中可见,但条形码行无法显示.我在LiveCycle中尝试了其他几个条形码选项,但都给出了相同的结果.

    OurJavaPage.java 
    public class ExampleForm extends BaseOutput { 
    private static final Log LOG = LogFactory.getLog(ExampleForm.class); 
    public OutputStream generate() throws IOException, DocumentException { 
        ByteArrayOutputStream baos = new ByteArrayOutputStream(); 
        PdfReader reader; 
        reader = new PdfReader(BASEDIR + "MailingExample.pdf"); 

        PdfStamper stamper = new PdfStamper(reader, baos); 
        Participant participantHome = home.getParticipant(); 
        Set<Location> homeLocs = participantHome.getLocations(); 

        final AcroFields form = stamper.getAcroFields(); 

        setFormField(form, "addrNumber[0]", addrMaster.getStreetNum()); 
        setFormField(form, "dateMiddle[0]", formatDate("MM-dd-yyyy", new Date())); 

// *********** Here's the problem *****************************
        setFormField(form, "Code128ABarcode1[0]", "20099002");
// ************************************************************

        debugAcrobatForm("ExampleForm", form); 
        stamper.setFormFlattening(true); 
        stamper.close(); 

        return baos; 
    } 
}

操作系统: Linux
编程: Java,.jsp,iText
软件: Adobe Live Cycle Designer ES 8.1

问题解决了!!!

我联系了iText,他们建议我改变这一行.

来自: stamper.setFormFlattening(true);
To: stamper.setFormFlattening(false);

有效.
