目的：通过java concurrent调用XML Publisher API处理XML Data Definition和rtf 模板生成PDF报表。

环境：Oracle EBS R12.0.4

技术：Oracle, Java, XML Publisher

步骤：

1.创建XML数据定义文件（EmpDataTemplate.xml）并上传至服务器的/home/applprod/test4bip/目录：

<?xml version="1.0" encoding="UTF-8" ?> <dataTemplate name="EmpData" description="Employee Details" Version="1.0"> <parameters> <parameter name="p_DeptNo" dataType="character" /> </parameters> <dataQuery> <sqlStatement name="Q1"> <!--[CDATA[ SELECT d.DEPTNO DEPTNO ,d.DNAME DNAME ,d.LOC LOC ,e.EMPNO EMPNO ,e.ENAME ENAME ,e.JOB JOB ,e.MGR MGR ,e.HIREDATE HIREDATE ,e.SAL SAL ,nvl(e.COMM, 0) COMM FROM scott.dept d ,scott.emp e WHERE d.deptno = e.deptno AND d.deptno = nvl( :p_DeptNo, d.deptno) ]]--> </sqlStatement> </dataQuery> <dataStructure> <group name="G_DEPT" source="Q1"> <element name="DEPT_NUMBER" value="DEPTNO" /> <element name="DEPT_NAME" value="DNAME" /> <element name="LOCATION" value="LOC" /> <element name="EMPLOYEE_NUMBER" value="EMPNO" /> <element name="NAME" value="ENAME" /> <element name="JOB" value="JOB" /> <element name="MANAGER" value="MGR" /> <element name="HIREDATE" value="HIREDATE" /> <element name="SALARY" value="SAL" /> <element name="COMMISSION" value="COMM" /> </group> </dataStructure> </dataTemplate>

2.创建rtf模板（EmpDataTemplate.rtf）并上传至服务器的/home/applprod/test4bip/目录：

3.创建java concurrent程序（EmpDataTemplate.java）。如果不能编译通过，需到服务器上的$JAVA_TOP目录下载相关类文件（可使用zip命令打包下载： zip -r ~/conclib ./oracle/apps/fnd/cp/*）：

package oracle.apps.fnd.cp;import java.sql.Connection;import oracle.apps.fnd.cp.request.CpContext;import oracle.apps.fnd.cp.request.JavaConcurrentProgram;import oracle.apps.xdo.dataengine.DataProcessor;import oracle.apps.fnd.util.ParameterList;import oracle.apps.fnd.cp.request.ReqCompletion;import oracle.apps.fnd.cp.request.OutFile;import oracle.apps.fnd.cp.request.LogFile;import oracle.apps.fnd.util.NameValueType;import oracle.apps.xdo.template.RTFProcessor;import oracle.apps.xdo.template.FOProcessor;import com.sun.java.util.collections.Hashtable;import java.io.File;public class EmpDataTemplate implements JavaConcurrentProgram { String deptNo; public void runProgram(CpContext cpContext) { { ParameterList params = cpContext.getParameterList(); ReqCompletion compl = cpContext.getReqCompletion(); OutFile outFile = cpContext.getOutFile(); LogFile logFile = cpContext.getLogFile(); logFile.writeln(">>1 start ..", LogFile.STATEMENT); while (params.hasMoreElements()) { NameValueType val = params.nextParameter(); if (val.getName().equals("P_DEPTNO")) deptNo = val.getValue(); } logFile.writeln(">>2 P_DEPTNO = " + deptNo, LogFile.STATEMENT); Connection jdbcConnection = cpContext.getJDBCConnection(); try { //Initialization – instantiate the DataProcessor class// DataProcessor dataProcessor = new DataProcessor(); //Set Data Template to be executed dataProcessor.setDataTemplate("/home/applprod/test4bip/EmpDataTemplate.xml"); logFile.writeln(">>3 dataProcessor.setDataTemplate", LogFile.STATEMENT); // Assign parameter Hashtable parameters = new Hashtable(); parameters.put("p_DeptNo", deptNo); dataProcessor.setParameters(parameters); logFile.writeln(">>4 dataProcessor.setParameters", LogFile.STATEMENT); // Set the jdbc connection dataProcessor.setConnection(jdbcConnection); logFile.writeln(">>5 dataProcessor.setConnection", LogFile.STATEMENT); // Specify the output directory and file for the data file dataProcessor.setOutput("/home/applprod/test4bip/EmpDetails.xml"); logFile.writeln(">>6 dataProcessor.setOutput", LogFile.STATEMENT); // Process the data template dataProcessor.processData(); logFile.writeln(">>6.1 dataProcessor.processData", LogFile.STATEMENT); // Convert rtf to xsl RTFProcessor rtfProcessor = new RTFProcessor("/home/applprod/test4bip/EmpDataTemplate.rtf"); logFile.writeln(">>7 new RTFProcessor()", LogFile.STATEMENT); rtfProcessor.setOutput("/home/applprod/test4bip/EmpDataTemplate.xsl"); rtfProcessor.process(); logFile.writeln(">>8 rtfProcessor.process()", LogFile.STATEMENT); // Geneate PDF FOProcessor foProcessor = new FOProcessor(); foProcessor.setData("/home/applprod/test4bip/EmpDetails.xml"); logFile.writeln(">>9 foProcessor.setData()", LogFile.STATEMENT); foProcessor.setTemplate("/home/applprod/test4bip/EmpDataTemplate.xsl"); logFile.writeln(">>10 foProcessor.setTemplate()", LogFile.STATEMENT); foProcessor.setOutput("/home/applprod/test4bip/EmpDetails001.pdf"); logFile.writeln(">>11 foProcessor.setOutput()", LogFile.STATEMENT); foProcessor.setOutputFormat(FOProcessor.FORMAT_PDF); foProcessor.generate(); logFile.writeln(">>12 foProcessor.generate() 001", LogFile.STATEMENT); compl.setCompletion(ReqCompletion.NORMAL, "Concurrent Normal Completed!"); } catch (Exception e) { compl.setCompletion(ReqCompletion.ERROR, e.toString()); } } }}

4.编译.java，将.class上传至服务器的$JAVA_TOP/oracle/apps/fnd/cp目录。

5.定义Executable：

6.定义Program，挂请求，测试。
