c128：EBS条形码打印

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
比较详尽的描述，其中的 IDAUTOMATION.PLL 中包含方法 Code128A， Code128B
及 Code128C 分别实现了 A,B,C 类 128 码的编码。具体的实现方法请参照 MetaLink
305090.1  。
第二种方法是通过 XML Publisher 实现 128 码的编码。因为超过 128  的 ASCII 码对
应的特殊字符在 PL/SQL 中无法显示，但是在 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 码就可以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  中提供了这种方法的实现。在 Metalink 782809.1[2]中提供 JAVA 版
128 码编码实现类(BarcodeUtil.java)的下载，以及测试使用相应的模板文件

(TestBarcodeUtil.rtf)

以下内容以字体IDAutomationC128M 为演示

一.WINDOWS本地字体配置

下载条形码字体，复制到系统字体文件夹里，自动安装

二，上传java到服务器

1.查看java里路径  例如：package oracle.apps.xdo.template.rtf.util.barcoder;

上传java文件BarcodeUtil.java到目录  $JAVA_TOP/oracle/apps/xdo/template/rtf/util/barcoder 没有新建

编译java文件

java文件如下

} } s = OnlyCorrectData; //Check for an even number of digits, add 0 if not even if( (s.length() % 2) == 1 ) { s = "0" + s; } //<<<< Calculate Modulo 103 Check Digit and generate // DataToPrint >>>>//Set WeightedTotal to the Code 128 value of // the start character weightedTotal = ((int)C128_Start) - 100;

} Printable_string = C128_Start + DataToPrint + C128_CheckDigit + C128_Stop + " "; Logger.log(Printable_string,5); return Printable_string; }} /*End BarcodeUtil class */
三，生成xml数据源

举例如下

<?xml version="1.0" encoding="UTF-8"?><RECEIPT_APPLIED><LINES><ITEM_CODE>F4990010010</ITEM_CODE><ITEM_NAME><![CDATA[财税通软件　V1.0]]></ITEM_NAME><BARCODE>912014266</BARCODE></LINES><LINES><ITEM_CODE>F4990010010</ITEM_CODE><ITEM_NAME><![CDATA[财税通软件　V1.0]]></ITEM_NAME><BARCODE>912014265</BARCODE></LINES></RECEIPT_APPLIED>
四.根据数据源制作模板

说明：REG里面   <?register-barcode-vendor:'oracle.apps.xdo.template.rtf.util.barcoder.BarcodeUtil';'XMLPBarVendor'?> 注册条码编码类

           条码里        <?format-barcode:BARCODE;'Code128a';'XMLPBarVendor'?>    数据格式化

五.注册数据源,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

由于我们的模板使用的是RTF格式的，因此Type需要选择FO To PDF

在XML Publisher Administrator职责下，定义字体转换映射关系

输入Font Family，这个值可以打开字体文件来查看

根据模板中使用字体的情况来选择Style和Weight

如果需要根据Locale来决定使用字体映射，则填入Language和Territory，不填代表所有语音环境下都适用

八，模板和字体映射关联

定义好字体映射之后，修改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按钮

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 Purpose   Scope   Details   Overview   Limitation   Steps to Implement   EnterpriseOne 8.98.3.0 and later (including 9.1):   EnterpriseOne 8.98.2.4 and older:   References APPLIES TO: JD Edwards EnterpriseOne Tools - Version 8.97 and later BI 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. PURPOSE Information 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. SCOPE Embedded BI Publisher for EnterpriseOne. DETAILS Overview Barcodes 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.  This can be archived in BI Publisher by invoking a java handler within the RTF template. The process works in two steps. First the BI Publisher engine merges the XML data with the template when submitting the report definition. Second the RTF template itself invokes the barcode java handler at runtime to add the control characters to the barcode string. Limitation Barcode 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 javascript to enable the start and stop control characters in PDF templates and this can only be done in RTF templates. Without the javascript, the font will show in the final output, however it will be unreadable to the barcode scanners. Steps to Implement EnterpriseOne 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'?> You may also want to try to use the barcode 128 font delivered with BI Publisher Desktop: 128R00.TTF. See article posted inhttps://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.    Obtain a java handler from the barcode vendor A sample of a barcode handler code is provided in the Oracle XML Publisher - Core Components Guide - Release 10.1.3.3 - Pages 8-60 to 8-64 (Document 704542.1) and included in the attachment BarcodeUtil.java This source file is provided only as a reference. The actual code should be provided by the barcode font vendor. Oracle does not support the creation or customization of the barcode java handler.    </
