Oracle 提供两种方式实现 128 码的编码
第一种方式是使用 Reports Builder 实现对 128 码编码， 在 Metalink 305090.1[1] 有
比較详尽的描写叙述，当中的 IDAUTOMATION.PLL 中包括方法 Code128A。 Code128B
及 Code128C 分别实现了 A,B,C 类 128 码的编码。详细的实现方法请參照 MetaLink
305090.1 。
另外一种方法是通过 XML Publisher 实现 128 码的编码。
三，生成xml数据源
四.依据数据源制作模板

第一种方式是使用 Reports Builder 实现对 128 码编码， 在 Metalink 305090.1[1] 有
比較详尽的描写叙述，当中的 IDAUTOMATION.PLL 中包括方法 Code128A。 Code128B
及 Code128C 分别实现了 A,B,C 类 128 码的编码。详细的实现方法请參照 MetaLink
305090.1 。
另外一种方法是通过 XML Publisher 实现 128 码的编码。
由于超过 128 的 ASCII 码对
应的特殊字符在 PL/SQL 中无法显示，可是在 128 码中使用这些字符作为 128 码的
起始终止位以及校验位。编码的过程放在 PL/SQL 端实现并生成 XML 数据结合模板
生成条码较难实现。改变思路，我们把编码过程放在 JAVA 类中。通过在结合模板
时调用生成 128 码就能够实现条码的生成和打印。
在《Oracle XML Publisher
Administration and Developer's Guide》中 Advanced Barcode Font Formatting
Implementation 中提供了这样的方法的实现。在 Metalink 782809.1[2]中提供 JAVA 版
128 码编码实现类(BarcodeUtil.java)的下载，以及測试使用对应的模板文件
(TestBarcodeUtil.rtf)
下面内容以字体IDAutomationC128M 为演示
一.WINDOWS本地字体配置
下载条形码字体，拷贝到系统字体目录里，自己主动安装
二，上传java到server
1.查看java里路径 比如：package oracle.apps.xdo.template.rtf.util.barcoder;
上传java文件BarcodeUtil.java到文件夹 $JAVA_TOP/oracle/apps/xdo/template/rtf/util/barcoder 没有新建
编译java文件
java文件例如以下

三，生成xml数据源
举比例如以下
四.依据数据源制作模板
说明：REG里面 <?register-barcode-vendor:'oracle.apps.xdo.template.rtf.util.barcoder.BarcodeUtil';'XMLPBarVendor'?> 注冊条码编码类
条码里 <?format-barcode:BARCODE;'Code128a';'XMLPBarVendor'?> 数据格式化
五.注冊数据源,模板
略
六.上传字体
在XML Publisher Administrator职责下，首先上传字体文件
七.配置字体映射
在XML Publisher Administrator职责下，定义字体转换映射集
因为我们的模板使用的是RTF格式的。因此Type须要选择FO To PDF
在XML Publisher Administrator职责下，定义字体转换映射关系
输入Font Family，这个值能够打开字体文件来查看
依据模板中使用字体的情况来选择Style和Weight
假设须要依据Locale来决定使用字体映射，则填入Language和Territory，不填代表全部语音环境下都适用
八，模板和字体映射关联
定义好字体映射之后，改动BIP模板文件的配置
查询出BIP模板定义后，点击右上角的 Edit Configuration button
查找模板
展开FO Processing部分，设置Font mapping set为上面定义好的字体映射集
最后提交请求，查看输出

In this Document
APPLIES TO:JD Edwards EnterpriseOne Tools - Version 8.97 and laterBI Publisher (formerly XML Publisher) - Version 11.1.1.5.0 to 11.1.1.5.0 [Release 11.1] Information in this document applies to any platform. PURPOSEInformation Center: BI Publisher in the JD Edwards EnterpriseOne Tools and Technology Product > Information Center: Using BI Publisher in the JD Edwards EnterpriseOne Tools and Technology Product > Note 1460779.2 This document outlines the steps to use barcode java handlers to add control characters to barcode content in reports produced by embedded BI Publisher for EnterpriseOne. SCOPEEmbedded BI Publisher for EnterpriseOne. DETAILSOverviewBarcodes are a representation of a string of data in a barcode font. In order to be readable by barcode scanners, data represented in barcode format need to be preceded and followed by their respective control characters. See external
page http://en.wikipedia.org/wiki/Code_128 for more information. LimitationBarcode encoding will not work if using a PDF type template with Embedded BI Publisher for EnterpriseOne. This is because there is no way to add the necessary call to the java script to enable the start and stop control characters in PDF templates and this can only be done in RTF templates. Without the java script, the font will show in the final output, however it will be unreadable to the barcode scanners. Steps to ImplementEnterpriseOne 8.98.3.0 and later (including 9.1):Since tools release 8.98.3.0 we include a newer BI Publisher core engine (10.1.3.4.1) which has built in support for barcode 128a,b,c. The barcode function can be invoked directly using te following command in your RTF template: <?format-barcode:FieldName;'code128b'?> Where FieldName is the name of the dynamic field you want to convert to Barcode 128b. You can use encodings 128a and 128c as well, for example: <?format-barcode:FieldName;'code128a'?> format-barcode:FieldName;'code128c'?> https://blogs.oracle.com/xmlpublisher/entry/bundled_barcodes_batman_1 for
more details. EnterpriseOne 8.98.2.4 and older:The following steps layout all pieces necessary to embed readable barcode strings in reports produced by BI Publisher for EnterpriseOne 8.98.2.4 and older.
The implementation of this solution requires knowledge of BI Publisher for EnterpriseOne and java programming language.
Note 1:
The same result can be achieved with BI Publisher Desktop (MS Word Plug-in), using its own xdocore.jar and its fonts. These are usually located in"c:\Program Files\Oracle\BI Publisher\BI Publisher Desktop\Template Builder for Word", in the jlib and fonts subfolders. If the issue is duplicated with the Desktop Plugin, then it is not an EnterpriseOne integration problem, and the cause should be sought either in the encryptor class from the barcode provider, or in the way it was integrated in the BarcodeUtil.java.
Note 2:
There are many different types of barcodes. This document is specific to handling of 128a, 128b and 128c types. It is possible to integrate other dynamic barcode types to use with BI Publisher for EnterpriseOne, however these are considered to be out of the scope of EnterpriseOne support.
