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

        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 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 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.    The java handler must contain three methods to be called by BI Publisher engine: getVendorID(); isSupported(String type); encode(String data, String type);   Take note of the package location specified in the java source (usually the first line) Example: package oracle.apps.xdo.template.rtf.util.barcoder;   Check the Java Runtime Environment (JRE) in use on the enterprise server where E1 XML PUBLISHER kernel runs. Login as the user who starts E1 services and issue command java -version from a command console. Note about AS/400: the Enterprise Server Minimum Technical Requirements referenced in document 747323.1 contains information about the necessary Java Developer Kit installed on this server platform.   Copy xdocore.jar file from EnterpriseOne enterprise server located in '..\system\classes' folder to a development workstation. Extract it using a tool such WinZip. Example: c:\temp   Compile BarcodeUtil.java using the same JRE version used on the enterprise server. So for instance, if in step 4 you found java version 1.4.2_05, use JDK 1.4.2 update 5 or greater to compile the java class. Problems might appear if the class is compiled using a major Java release different than the one on the Enterprise Server (the machine that will execute the java compiled code at runtime). Example: if you are compiling it on Windows development workstation where c:\temp contains the java source file, the JDK and xdocore.jar, you can use the following commands: set path=c:\temp\jdk_1.4.2_18\bin set classpath=c:\temp\xdocore.jar javac -g BarcodeUtil.java If there are no major problems with the code, this will create a file name BarcodeUtil.class inside c:\temp Note: In situations where a version of the JDK used on the server is not available on the Windows platform, follow the procedures in steps 5 and 6 on the enterprise server itself. This is usually the case with AIX and iSeries servers which use IBM J9 JDK. This information is provided only as a reference. Problems setting java compiler environment and with the compilation of the barcode java handler provided by 3rd party vendors are not supported by Oracle. Please refer to the respective vendor for further assistance.   Copy the new BarcodeUtil.class to the uncompressed structure of xdocore.jar you extracted in step 5. Place it in the same location given by the 'package' directive specified in the java source and found in step 3.  Example: if the java source contains: package oracle.apps.xdo.template.rtf.util.barcoder; place BarcodeUtil.class in folder name 'oracle\apps\xdo\template\rtf\util\barcoder' inside the extracted xdocore.   Compress all class files (which must include the new BarcodeUtil.class you added in step 7) into a jar file and name it xdocore.jar. You can use WinZip to create xdocore.zip and then rename it to xdocore.jar. Make sure you only compress the original folder structure, not any additional upper folder level. Check this by opening the original xdocore.jarand the new xdocore.jar files with a zip utility and comparing the folder structure. Stop EnterpriseOne services on the enterprise server and backup the original xdocore.jar inside ...\system\classes. Place the backup in a folder outside the system PATH and CLASSPATH folders otherwise the system might still use the old .jar file.   Copy xdocore.jar file created in step 8 to the enterprise server placing it in ...\system\classes   Take this opportunity to check you can find the jas and jasroot log files produced by EnterpriseOne JVM based kernels - See Document 651589.1section 'jas/jasroot/jasdebug'. The location where these logs are saved is configured in file jdelog.properties found in   ...\system\classes (on AS/400 it is in ...\system). Edit it and check if the parameter FILE points to the same folder where other E1 kernel logs are saved. These logs are helpful when troubleshooting BI Publisher issues.   Review the document 652457.1 to learn how to configure the barcode font in xdo.cfg file. Then configure the server xdo.cfg and copy the barcode truetype font to the enterprise server.   Start EnterpriseOne services on the enterprise server. Install the font on the development workstation. This should be the same font you uploaded to the enterprise server in step 12. All it usually takes is to copy the truetype font to the 'fonts' folder inside C:\WINDOWS.   Create a new template containing the following: Directive to register the barcode handler (note the java path must match the location of the class file in xdocore.jar as explained in item 7): For example: <?register-barcode-vendor:'oracle.apps.xdo.template.rtf.util.barcoder.BarcodeUtil';'XMLPBarVendor'?> Invoke the handler using the 'format-barcode' directive: For example: <?format-barcode:xml_field_name;'code128b';'XMLPBarVendor'?> See section titled Register the Barcode Encoding Class in the Oracle XML Publisher Core Components guide page 2-118 and 2-119 for more information see document 704542.1 See attached file TestBarcodeUtil.rtf for a sample template.   On the template, change the font of the data field to be encoded to be displayed using the barcode font you installed in step 14.   Create a BI Publisher object using program P95600, upload the template you created in step 15, then create a report definition and associate it to the BI Publisher object. Submit it to the server and check the status of the output; it should be 'D' for done. If you get a status 'FX' this means that an error occurred when merging data and template. If that happened, check the jas log you setup in step 11 and look for errors. Normally java exceptions in the log will tell where the error occurred.    To verify that the java handler class is being called correctly, change the font on the data field to a humanly readable font, say Arial and run the report definition again. In the final output you should see the encoded value of the data formatted by the barcode handler.  If the output is the same as the data in the XML field then the BarcodeUtil handler is not being called correctly. Below is a screenshot showing the output obtained using the steps above on EnterpriseOne 9.0 with tools release 8.98.2.4: 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.  If you have questions about using 2D barcode fonts you may like to consider the following links:  https://blogs.oracle.com/xmlpublisher/entry/bundled_barcodes_batman_1  https://blogs.oracle.com/xmlpublisher/entry/2d_barcodes_cracked https://blogs.oracle.com/xmlpublisher/entry/2d_barcode_addendum http://www.idautomation.com/oracle/xml_publisher_barcode.html.

Oracle Reports Barcode Tutorial & FAQ

This IDAutomation tutorial should be used when implementing barcode generation in Oracle Reports with the IDAutomation PL/SQL Barcode Library and IDAutomation barcode fonts. The barcode library is a PLL file that formats data from fields in the report to create
an accurate barcode when combined with IDAutomation barcode fonts.

The library contains functions for Code 128, Code 39, GS1, Codabar, UCC/EAN 128, Interleaved 2 of 5, UPC and EAN barcodes.

IDAutomation also provides Java barcode generation for Oracle Reports, which is easier to implement
in for versions 9i, 10g and above, as well as in UNIX and Linux environments. Other solutions are also provided in the Oracle
Reports Barcode Integration Guide.

Note: Use of this pll, requires a Developer License or above. This font encoder is supplied with Purchase of Developer's License or above of any Barcode Font Package.

Oracle Barcode Font Implementation Tutorial

Step 1: Install the Barcode Fonts

IDAutomation offers many different barcode fonts for a variety of purposes. If unsure which to use, consider theUniversal
Barcode Font with the Code 128 function. The IDAutomation.pll is a Feature
Level 3 font encoder and cannot format data for the GS1-128 barcode standard. The IDAutomation_Universal.pll (compatible with Oracle 9i and above) can encode data for GS1-128 barcodes. To install these barcode fonts on Windows for Oracle Reports, run theInstall.exe file
included in the font package or follow the font installation procedures. Because of the complexities and variety
of UNIX and Linux system distributions, IDAutomation does not provide installation assistance for these systems. However, IDAutomation does provide two sets of installation instructions that may help as a guide:

1. Installing Fonts on Unix for Oracle Reports
2. Font Installation on Unix and Other Systems

If possible, consider using Java Barcoding for Oracle Reports for Unix and Linux environments.

Step 2: Install the Oracle Reports Barcode PLL Library

The Oracle Reports Barcode PLL Library is compatible with all versions of Oracle Reports that support attached libraries. The IDAutomation.pll was developed and tested against Reports 6i, and the IDAutomation_Universal.pll is
compatible with 10g and above. If used in the database itself, the version of the database would be any version that supports PL/SQL. PL/SQL source code is also provided for advanced Oracle developers in the IDAutomation.pkg file.

1. Open Oracle Reports Builder.
2. Open the report rdf file that will contain the barcodes.
3. Select the attached libraries option.
4. Press the create button (Green Plus symbol) on the left toolbar.
5. In the dialog box, select the File System radio button, click on the Browse button.
6. Included in the Developer Tool's folder of the licensed font package will be the Oracle Barcode Library Tool, which contains the IDAutomation.pll and IDAutomation_Universal.pll files.
   After decompressing, save these files to an appropriate directory.
7. Select the IDAutomation.pll or the IDAutomation_Universal.pll file
   and choose the Attach button. If not sure which to use, consider the IDAutomation_Universal.pll file
   with the IDAutomation Universal Barcode Font.
8. A dialog box will appear asking to remove the path. If Yes is selected, the PL/SQL library will need to be reattached to the report every time the report is opened. If No is selected, it will always look for the path in the same location.
   Leaving the library in the same directory as the report is encouraged.
9. The barcode functions in the library are now ready to be used in the report. After the library is attached, the Object Navigator should look similar to the screen shot below, which shows the attached IDAutomation_Universal.pll.
   
    

Step 3: Set Up the Function Call with the Barcode Font

1. IDAutomation's barcode library contains many font functions for linear barcodes. Add a Formula
   Column to the report by using the Data Model option of the Report Layout, clicking the Formula Column button on the toolbar, and sizing the column in the layout area.
   
   
2. The newly added Formula Column properties need to be adjusted to call the PL/SQL function from theIDAutomation.pll library. Access the property page for the Formula Column by selecting the Formula
   Column and pressing the F4 key. The following window will appear:
   
   
3. Adjust the following properties:
   1. Name: Choose a descriptive name for the Formula Column because the columns will need to be referenced when designing the layout of the actual report.
   2. Datatype: This must be selected as Character from the drop-down menu.
   3. Width: Ensure the width of the field is large enough to hold all encoded characters.
4. Click on the PL/SQL Formula button within the Property Inspector to call the appropriate barcode function. The following screen should appear:
   
   
5. Insert the appropriate function call where the cursor is positioned within the report to add the appropriate start and stop characters, encode the data if necessary and add the check sum character, when required.
   
   
6. In the above example, a constant value (Code128Test) was passed into this function. If necessary, the appropriate character field may be substituted from the database.
7. Click Close in the above window and ensure the report has been saved.
8. To add this Formula Column to the report, switch to Paper Layout mode for the report and add a Field object to the report by clicking the appropriate item in the toolbar and dragging into position on the report.
   
   
9. Once the Field has been added to the report, link it to the Formula Column that was created earlier. To link theField to the Formula Column, select the field and hit the F4 button
   to bring up the Property Inspector for the Field. The Property Inspector should look similar to the following:
   
   
10. Adjust the following properties:
    1. Name: Choose a descriptive name for the field (optional).
    2. Source: Select the name of Formula Column that was created earlier (required). 
11. Modify the font of the field to the appropriate barcode font according to the Oracle Reports Barcode Font Functions chart below.

Function Property Descriptions

• DataToEncode: A string value that represents the data being encoded.
• N_Dimension: Determines the width of the wide bars which is a multiple of the X dimension. Valid values are 2, 2.5 and 3. The default is 2. The X dimension
  is determined by the font point size.
• IncludeCheckDigit: A Boolean value that determines whether a check digit should be automatically calculated and included for the DataToEncode.
• ApplyTilde: If set to True, characters following the tilde may be used to perform
  additional calculations or encode ASCII characters directly.
