Hi,
I was able to execute my report from eclipse. But when i tried to
execute it from a standalone java program(it is written in JBuilder), i
got the following error.
Exception in thread "main" java.lang.NullPointerException
at
org.eclipse.birt.report.engine.api.ReportEngine.openReportDe sign(ReportEngine.java:111)
at subsreqrequest.RRTest.main(RRTest.java:27)
Can't load the report engine
Here is my program
package subsreqrequest;
import org.eclipse.birt.report.engine.api.*;
import org.eclipse.birt.core.framework.Platform;
import org.eclipse.birt.core.exception.*;
import org.eclipse.birt.report.engine.api.EngineConfig;
import org.eclipse.birt.report.engine.api.EngineException;
import org.eclipse.birt.report.engine.api.HTMLRenderOption;
import org.eclipse.birt.report.engine.api.IReportEngine;
import org.eclipse.birt.report.engine.api.IReportRunnable;
import org.eclipse.birt.report.engine.api.IRunAndRenderTask;
public class RRTest {
public RRTest() {
}
public static void main(String[] args) {
RRTest rrtest = new RRTest();
try {
EngineConfig config = new EngineConfig();
config.setEngineHome("C:/birt-runtime-2_1_1/ReportEngine");
System.out.println("EngineHome: " + config.getBIRTHome());
IReportEngine engine = new ReportEngine(config);
IReportRunnable design = engine.openReportDesign(
"C:/sampreport/Subs.rptdesign");
design.getReportName();
IRunAndRenderTask task = engine.createRunAndRenderTask(design);
java.util.Calendar cal = java.util.Calendar.getInstance();
cal.set(2007, 10, 10);
task.setParameterValue("BeginDate", cal.getTime());
cal.set(2007, 11, 05);
task.setParameterValue("EndDate", cal.getTime());
task.setParameterValue("SubscriptionResult", new Integer(2));
task.setParameterValue("DorUserType", new Integer(0));
task.setParameterValue("TaxType", new Integer(2));
IRenderOption setting = new HTMLRenderOption();
setting.setOutputFileName("C:/temp/test.html");
task.setRenderOption(setting);
System.out.println("task: " + task.getRenderOption());
task.run();
task.close();
engine.shutdown();
System.out.println("Finished");
}
catch (EngineException ex) {
ex.printStackTrace();
}
}
}
I have included all the required libraries in corresponding
places.
Please some body help me..........

It looks like the engine is not starting up. Try code similar to this:
