使用java concurrent調用xmlp api生成pdf

目的：通過java concurrent調用XML Publisher API處理XML Data Definition和rtf 模板生成PDF報表。

環境：Oracle EBS R12.0.4

技術：Oracle, Java, XML Publisher

 

步驟：

 

1.創建XML數據定義文件（EmpDataTemplate.xml）並上傳至服務器的/home/applprod/test4bip/目錄：

[xhtml] view plaincopy

1. <?xml version="1.0" encoding="UTF-8" ?>   
2.  <dataTemplate name="EmpData" description="Employee Details" Version="1.0">  
3.     <parameters>  
4.         <parameter name="p_DeptNo" dataType="character" />   
5.     </parameters>  
6.  <dataQuery>  
7.     <sqlStatement name="Q1">  
8.     <!--[CDATA[   
9.     SELECT d.DEPTNO DEPTNO  
10.           ,d.DNAME DNAME  
11.           ,d.LOC LOC  
12.           ,e.EMPNO EMPNO  
13.           ,e.ENAME ENAME  
14.           ,e.JOB JOB  
15.           ,e.MGR MGR  
16.           ,e.HIREDATE HIREDATE  
17.           ,e.SAL SAL  
18.           ,nvl(e.COMM, 0) COMM  
19.       FROM scott.dept d  
20.           ,scott.emp  e  
21.      WHERE d.deptno = e.deptno  
22.        AND d.deptno = nvl( :p_DeptNo, d.deptno)  
23.     ]]-->   
24.     </sqlStatement>  
25.   </dataQuery>  
26.   <dataStructure>  
27.     <group name="G_DEPT" source="Q1">  
28.         <element name="DEPT_NUMBER"      value="DEPTNO" />   
29.         <element name="DEPT_NAME"        value="DNAME" />   
30.         <element name="LOCATION"     value="LOC" />   
31.         <element name="EMPLOYEE_NUMBER" value="EMPNO" />   
32.         <element name="NAME"         value="ENAME" />   
33.         <element name="JOB"              value="JOB" />   
34.         <element name="MANAGER"          value="MGR" />   
35.         <element name="HIREDATE"     value="HIREDATE" />   
36.         <element name="SALARY"           value="SAL" />   
37.         <element name="COMMISSION"       value="COMM" />   
38.     </group>  
39.   </dataStructure>  
40.  </dataTemplate>  

 

2.創建rtf模板（EmpDataTemplate.rtf）並上傳至服務器的/home/applprod/test4bip/目錄：

 

3.創建java concurrent程序（EmpDataTemplate.java）。如果不能編譯通過，需到服務器上的$JAVA_TOP目錄下載相關類文件（可使用zip命令打包下載： zip -r ~/conclib ./oracle/apps/fnd/cp/*）：

[java] view plaincopy

1. package oracle.apps.fnd.cp;  
2.   
3. import java.sql.Connection;  
4. import oracle.apps.fnd.cp.request.CpContext;  
5. import oracle.apps.fnd.cp.request.JavaConcurrentProgram;  
6. import oracle.apps.xdo.dataengine.DataProcessor;  
7. import oracle.apps.fnd.util.ParameterList;  
8. import oracle.apps.fnd.cp.request.ReqCompletion;  
9. import oracle.apps.fnd.cp.request.OutFile;  
10. import oracle.apps.fnd.cp.request.LogFile;  
11. import oracle.apps.fnd.util.NameValueType;  
12. import oracle.apps.xdo.template.RTFProcessor;  
13. import oracle.apps.xdo.template.FOProcessor;  
14. import com.sun.java.util.collections.Hashtable;  
15. import java.io.File;  
16.   
17. public class EmpDataTemplate implements JavaConcurrentProgram {  
18.   
19.     String deptNo;  
20.   
21.     public void runProgram(CpContext cpContext) {  
22.         {  
23.   
24.             ParameterList params = cpContext.getParameterList();  
25.             ReqCompletion compl = cpContext.getReqCompletion();  
26.             OutFile outFile = cpContext.getOutFile();  
27.             LogFile logFile = cpContext.getLogFile();  
28.             logFile.writeln(">>1 start ..", LogFile.STATEMENT);  
29.   
30.             while (params.hasMoreElements()) {  
31.                 NameValueType val = params.nextParameter();  
32.                 if (val.getName().equals("P_DEPTNO"))  
33.                     deptNo = val.getValue();  
34.   
35.             }  
36.   
37.             logFile.writeln(">>2 P_DEPTNO = " + deptNo, LogFile.STATEMENT);  
38.   
39.             Connection jdbcConnection = cpContext.getJDBCConnection();  
40.   
41.             try {  
42.   
43.                 //Initialization – instantiate the DataProcessor class//  
44.                 DataProcessor dataProcessor = new DataProcessor();  
45.   
46.                 //Set Data Template to be executed  
47.                 dataProcessor.setDataTemplate("/home/applprod/test4bip/EmpDataTemplate.xml");  
48.                 logFile.writeln(">>3 dataProcessor.setDataTemplate",  
49.                                 LogFile.STATEMENT);  
50.                   
51.                 // Assign parameter  
52.                 Hashtable parameters = new Hashtable();  
53.                 parameters.put("p_DeptNo", deptNo);  
54.                 dataProcessor.setParameters(parameters);  
55.                 logFile.writeln(">>4 dataProcessor.setParameters",  
56.                                 LogFile.STATEMENT);  
57.   
58.                 // Set the jdbc connection  
59.                 dataProcessor.setConnection(jdbcConnection);  
60.                 logFile.writeln(">>5 dataProcessor.setConnection",  
61.                                 LogFile.STATEMENT);  
62.   
63.                 // Specify the output directory and file for the data file  
64.                 dataProcessor.setOutput("/home/applprod/test4bip/EmpDetails.xml");  
65.                 logFile.writeln(">>6 dataProcessor.setOutput",  
66.                                 LogFile.STATEMENT);  
67.   
68.                 // Process the data template  
69.                 dataProcessor.processData();  
70.                 logFile.writeln(">>6.1 dataProcessor.processData",  
71.                                 LogFile.STATEMENT);  
72.   
73.                 // Convert rtf to xsl  
74.                 RTFProcessor rtfProcessor =  
75.                     new RTFProcessor("/home/applprod/test4bip/EmpDataTemplate.rtf");  
76.                 logFile.writeln(">>7 new RTFProcessor()", LogFile.STATEMENT);  
77.   
78.                 rtfProcessor.setOutput("/home/applprod/test4bip/EmpDataTemplate.xsl");  
79.                 rtfProcessor.process();  
80.   
81.                 logFile.writeln(">>8 rtfProcessor.process()",  
82.                                 LogFile.STATEMENT);  
83.   
84.                 // Geneate PDF  
85.                 FOProcessor foProcessor = new FOProcessor();  
86.                 foProcessor.setData("/home/applprod/test4bip/EmpDetails.xml");  
87.                 logFile.writeln(">>9 foProcessor.setData()",  
88.                                 LogFile.STATEMENT);  
89.   
90.                 foProcessor.setTemplate("/home/applprod/test4bip/EmpDataTemplate.xsl");  
91.                 logFile.writeln(">>10 foProcessor.setTemplate()",  
92.                                 LogFile.STATEMENT);  
93.   
94.                 foProcessor.setOutput("/home/applprod/test4bip/EmpDetails001.pdf");  
95.                 logFile.writeln(">>11 foProcessor.setOutput()",  
96.                                 LogFile.STATEMENT);  
97.                 foProcessor.setOutputFormat(FOProcessor.FORMAT_PDF);  
98.                 foProcessor.generate();  
99.                 logFile.writeln(">>12 foProcessor.generate() 001",  
100.                                 LogFile.STATEMENT);  
101.   
102.                 compl.setCompletion(ReqCompletion.NORMAL,  
103.                                     "Concurrent Normal Completed!");  
104.   
105.             } catch (Exception e) {  
106.                 compl.setCompletion(ReqCompletion.ERROR, e.toString());  
107.             }  
108.         }  
109.   
110.   
111.     }  
112. }  

 

4.編譯EmpDataTemplate.java，將EmpDataTemplate.class上傳至服務器的$JAVA_TOP/oracle/apps/fnd/cp目錄。

 

 

 

 

 

 

 

5.定義Executable：

Executable	Short Name	Application	Execution Method	Execution File Name	Execution File Path
XXFND_JAVAXMLP	XXFND_JAVAXMLP	Application Object Library	Java Concurrent Program	EmpDataTemplate	oracle.apps.fnd.cp

 

6.定義Program，掛請求，測試。
