Good day,
Im just starting to use BIRT after using Eclipse technolegies like RAP its getting use to this system. Up 2 now it all worked as I expected. I have been using Intergrating and Extending BIRT book as a guide. And it worked like a charm.
Now only one thing seems to be failing when I try my tests.
I created a repport with some variables:
<parameters>
<scalar-parameter name="REPORT_ID" id="419" extends="SMARTAPPS.NL.REPORT_ID"/>
<scalar-parameter name="DATABASE_NAME" id="420" extends="SMARTAPPS.NL.DATABASE_NAME"/>
<scalar-parameter name="REPORT_NAME" id="421" extends="SMARTAPPS.NL.REPORT_NAME"/>
<scalar-parameter name="ADVISEUR_ID" id="422" extends="SMARTAPPS.NLT.ADVISEUR_ID"/>
<scalar-parameter name="DATUM_START" id="423" extends="SMARTAPPS.NL.DATUM_START"/>
<scalar-parameter name="DATUM_EIND" id="424" extends="SMARTAPPS.NL.DATUM_EIND"/>
</parameters>
Now I wanted to test how the handlers work so I created a simpel Handler:
import java.util.Date;
import org.eclipse.birt.report.engine.api.script.IReportContext;
import org.eclipse.birt.report.engine.api.script.element.IReportDesign;
import org.eclipse.birt.report.engine.api.script.eventadapter.ReportEventAdapter;
import org.eclipse.birt.report.model.api.ReportDesignHandle;
import org.eclipse.birt.report.model.api.activity.SemanticException;
/**
* @author Martijn Cremer
* Test of a Report Event handler (for smartapps Algemeen)
*/
public class ReportEventHandler extends ReportEventAdapter {
@Override
public void beforeFactory(IReportDesign report, IReportContext reportContext) {
@SuppressWarnings("deprecation")
final Date date = new Date(2001, 01, 01);
if ((Date) reportContext.getPageVariable("DATUM_START") == date) {
final ReportDesignHandle rdh = (ReportDesignHandle) reportContext.getReportRunnable().getDesignHandle();
try {
rdh.findElement("VOORBLAD_REPPORT_ID").drop();
} catch (final SemanticException e) {
e.printStackTrace();
}
}
}
}
Now when I run it in Eclipse BIRT and BIRT Designer Professional i get the following error when I run my report:

What am I doing wrong?
I put the Java project containing the handler in the same workbench. As all the documentation i found and read told me. I'm probably missing somting very simple.
