Pass date parameters to dataprocessor in Java

Question

Hello I have created java class to execute data templates, but I have problem when I pass date parameters as it was from application dataprocessor fails without any error message and does not return any data (except output xml file header). How to pass date parameters correctly?
import java.sql.*;
import oracle.apps.xdo.dataengine.DataProcessor;
import com.sun.java.util.collections.Hashtable;
class oraConn
public static void main (String args []) throws SQLException
System.out.println("Start");
try {
DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());
java.util.Properties ora_property = new java.util.Properties();
Connection conn =
DriverManager.getConnection("jdbc:oracle:thin:user/pass@host:port:sid");
try {
DataProcessor dataProcessor = new DataProcessor();
dataProcessor.setDataTemplate("/home/user/definition.xml");
Hashtable parameters = new Hashtable();
parameters.put("c_period_start_date","2009/01/01 00:00:00");
parameters.put("c_period_end_date","2009/12/31 00:00:00");
parameters.put("c_employed_before_date","");
parameters.put("c_org_hierarchy","63");
dataProcessor.setParameters(parameters);
dataProcessor.setConnection(conn);
dataProcessor.setOutput("/home/user/Out.xml");
dataProcessor.processData();
} catch (Exception e)
{System.out.println ("Data procesor Fail.");}
} catch (SQLException ex) {
System.out.println ("\n*** SQLException caught ***\n");
while (ex != null) {
System.out.println ("SQLState: " + ex.getSQLState ());
System.out.println ("Message: " + ex.getMessage ());
System.out.println ("Vendor: " + ex.getErrorCode ());
ex.printStackTrace();
ex = ex.getNextException ();
System.out.println ("");
}}}}

Found out solution to my problem. I needed to import date not as string but as Date type.
