Using the Data Engine Java API

Question

I try to use the Data Engine Java API to generate an XML document from database data.
So as mentioned in the documentation Business Intelligence Publisher User's Guide Release 10.1.3.2 (page 4-26 to 4-27)
a) I created a java class (using Jdev Version 11.1.1.0.0)
package oracle.apps.XMLPublisher.client;
import com.sun.java.util.collections.Hashtable;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Statement;
import oracle.apps.xdo.XDOException;
import oracle.apps.xdo.dataengine.DataProcessor;
public class XMLFileGenerator {
public XMLFileGenerator() {
public static void dataEngine() throws ClassNotFoundException, Exception {
XMLFileGenerator xMLFileGenerator = new XMLFileGenerator();
try {
//Initialization instantiate the DataProcessor class//
DataProcessor dataProcessor;
dataProcessor = new DataProcessor();
//Set Data Template to be executed
dataProcessor.setDataTemplate("PERFRBS.xml");
Hashtable parameters;
parameters = new Hashtable();
parameters.put("P_LEGAL_ENTITY_ID", "3259");
parameters.put("P_TRU_ID", "3262");
parameters.put("P_YEAR", "2009");
dataProcessor.setParameters(parameters);
// Now set the jdbc connection to the database that you
// wish to execute the template against.
// This sample assumes you have already created
// the connection object 'jdbcConnection'
Class.forName("oracle.jdbc.OracleDriver");
String url =
"jdbc:oracle:thin:@ap6005sdb.us.oracle.com:1526:hremeadv";
Connection jdbcConnection;
jdbcConnection= DriverManager.getConnection(url, "apps", "*****");
dataProcessor.setConnection(jdbcConnection);
System.out.println("Here1");
// Specify the output directory and file for the data file
dataProcessor.setOutput("BilanSocial.xml");
System.out.println("Here2");
dataProcessor.processData();
System.out.println("Here3");
} catch (SQLException e) {
System.out.println("SQLException " + e.getMessage());
} catch (XDOException e) {
System.out.println("XDOException" + e.getMessage());
public static void main(String[] argv) throws ClassNotFoundException,
Exception {
XMLFileGenerator xmlPublisher = new XMLFileGenerator();
XMLFileGenerator.dataEngine();
b) to generate my xml file based on the following data template
<?xml version="1.0" encoding="ISO-8859-1" ?>
<dataTemplate name="PERFRBS" defaultPackage="" version="1.0">
<parameters>
<parameter name="P_LEGAL_ENTITY_ID" dataType = "number"></parameter>
<parameter name="P_TRU_ID" dataType = "number"></parameter>
<parameter name="P_YEAR" dataType = "number"></parameter>
</parameters>
<lexicals>
</lexicals>
<dataQuery>
<sqlStatement name="Q_INDICATORS">
<![CDATA[ SELECT pai.action_information3   YEAR,
                pai.action_information17  INDICATOR_VALUE
          FROM   pay_action_information pai 
         WHERE  pai.action_information_category     = 'HR_FR_BS'
            AND    pai.action_context_type             = 'PA'
            AND    pai.action_information1             = :P_LEGAL_ENTITY_ID
            AND    pai.action_information2             = :P_TRU_ID
            AND    pai.action_information3            = :P_YEAR       
]]>
</sqlStatement>
</dataQuery>
<dataStructure>
<group name="G_YEARS" dataType="varchar2" source="Q_INDICATORS">
<element name="YEAR" dataType="varchar2" value="YEAR"/>
<element name="INDICATOR_VALUE" dataType="number" value="INDICATOR_VALUE"/>
</group>
</dataStructure>
</dataTemplate>
---> But when I run it , it fails when calling the data processor with the following error
D:\Jdeveloper11g\jdk\bin\javaw.exe -client -classpath "D:\Jdeveloper11g\jdevhome\XMLPublisher\src\Client\classes;D:\BI publisher\XMLP562_WIN\XMLP562_WIN\manual\lib\versioninfo.jar;D:\BI publisher\XMLP562_WIN\XMLP562_WIN\manual\lib\xdocore.jar;D:\BI publisher\XMLP562_WIN\XMLP562_WIN\manual\lib\collections.jar;D:\BI publisher\XMLP562_WIN\XMLP562_WIN\manual\lib\xmlparserv2-904.jar;D:\BI publisher\XMLP562_WIN\XMLP562_WIN\manual\lib\i18nAPI_v3.jar;D:\Jdeveloper11g\jdbc\lib\ojdbc14dms.jar;D:\Jdeveloper11g\jlib\orai18n.jar;D:\Jdeveloper11g\diagnostics\lib\ojdl.jar;D:\Jdeveloper11g\jlib\dms.jar" -Dhttp.proxyHost=emeacache.uk.oracle.com -Dhttp.proxyPort=80 -Dhttp.nonProxyHosts= -Dhttps.proxyHost=emeacache.uk.oracle.com -Dhttps.proxyPort=80 -Dhttps.nonProxyHosts= oracle.apps.XMLPublisher.client.XMLFileGenerator

Thanks by advance for your help

Make sure you have the Oracle JDBC library setup in project parties and it's setup to export. The api's are fine. Have you looked at the BIPublisherIDE I wrote. All this code is already written for you. There is a manual on the site as well
