Exception when using rptdesign file in struts2 project

Prakash.M

Hi all,
Am using birt-4.2 and using the following code to use rptdesign file in standalone java project.

**********************
import java.util.logging.Level;

import org.eclipse.birt.core.framework.Platform;
import org.eclipse.birt.report.engine.api.EngineConfig;
import org.eclipse.birt.report.engine.api.HTMLRenderOption;
import org.eclipse.birt.report.engine.api.IReportEngine;
import org.eclipse.birt.report.engine.api.IReportEngineFactory;
import org.eclipse.birt.report.engine.api.IReportRunnable;
import org.eclipse.birt.report.engine.api.IRunAndRenderTask;
import org.eclipse.birt.report.engine.api.PDFRenderOption;

import com.opensymphony.xwork2.ActionSupport;

public class ExecuteReport extends ActionSupport {
public String execute() {
try {
EngineConfig config = new EngineConfig();
//config.setBIRTHome("F:/birt-runtime-3_7_2/ReportEngine");
config.setLogConfig("c:/temp", Level.FINE);
Platform.startup(config);
IReportEngineFactory factory = (IReportEngineFactory) Platform
.createFactoryObject(IReportEngineFactory.EXTENSION_REPORT_ENGINE_FACTORY);
IReportEngine engine = factory.createReportEngine(config);
IReportRunnable design = null;
// Open the report design
design = engine.openReportDesign("C:/name.rptdesign");
IRunAndRenderTask task = engine.createRunAndRenderTask(design);
PDFRenderOption options1 = new PDFRenderOption();
options1.setOutputFileName("C:/test.pdf");
options1.setOutputFormat("pdf");
task.setRenderOption(options1);
HTMLRenderOption option = new HTMLRenderOption();
option.setOutputFileName("C:/name.html");
option.setOutputFormat("html");
task.setRenderOption(option);
task.run();
task.close();
engine.destroy();
Platform.shutdown();// shutdown the platform

}catch(Exception e){
System.out.println(e);

}
return "success";
}
}
*****************************
I ve mapped the above class for the action name. so when am trying to run the project using tomcat6 its showing the following exception.
