Hi jikang,<br />
<br />
Do you mean how to convert a report design (rptdesign) into a report document (rptdocument is an occurance of an executed report)? If so, there are examples at <a class='bbc_url' href='http://www.birt-exchange.org/devshare/deploying-birt-reports/568-execute-birt-reports-from-java-class/#description'>Execute BIRT Reports from Java class - Designs & Code - BIRT Exchange</a><br />
<br />
Otherwise, there is no way to go backwards from completed report document, back into a design.

The following code snippet will extract the report design from a rptdocument file and save.

package birt.executor;

import java.io.IOException;

import org.eclipse.birt.core.exception.BirtException;
import org.eclipse.birt.core.framework.Platform;
import org.eclipse.birt.report.engine.api.EngineConfig;
import org.eclipse.birt.report.engine.api.EngineException;
import org.eclipse.birt.report.engine.api.IReportDocument;
import org.eclipse.birt.report.engine.api.ReportEngine;

public class RestoreReportDesign {

/**
* @param args
*/
public static void main(String[] args) {
try {
String birtHome = "C:/Libraries/birt-runtime-2_3_2/ReportEngine";

EngineConfig engineConfig = new EngineConfig();
engineConfig.setBIRTHome(birtHome);

Platform.startup(engineConfig);

ReportEngine re = new ReportEngine(engineConfig);

IReportDocument doc = re.openReportDocument("Completed.rptdocument");

doc.getReportDesign().saveAs("extractedReportDesign.rptdesign");

doc.close();
Platform.shutdown();
} catch (EngineException e) {
e.printStackTrace();
} catch (BirtException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}

}

}

thanks John... I didn't even know this was possible... Thanks for posting the code snippet.
