Render TOC in Java code in my application [message #1014486]

Mon, 25 February 2013 17:46

I find out the following tasks during debug:

1. BirtViewerReportService.transformTOCNode(TOCNode)
2. BirtGetTOCActionHandler.prepareResponse()
create org.eclipse.birt.report.soapengine.api.Update object
GetUpdatedObjectsResponse.setUpdate(Update)

I don't want to use SOAP api to render TOC. instead I want to use Java api to render it. How do I do it?

Thanks,

James,

Can you try something like:

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.EngineException;
import org.eclipse.birt.report.engine.api.IReportDocument;
import org.eclipse.birt.report.engine.api.IReportEngine;
import org.eclipse.birt.report.engine.api.IReportEngineFactory;
import org.eclipse.birt.report.engine.api.TOCNode;

public class Toc {

public void runReport() throws EngineException
{

IReportEngine engine=null;
EngineConfig config = null;

try{

config = new EngineConfig( );
config.setLogConfig(null, Level.FINE);
Platform.startup( config );
IReportEngineFactory factory = (IReportEngineFactory) Platform.createFactoryObject( IReportEngineFactory.EXTENSION_REPORT_ENGINE_FACTORY );
engine = factory.createReportEngine( config );
}catch( Exception ex){
ex.printStackTrace();
}

IReportDocument document = null;
//Open the report design
document = engine.openReportDocument("output/resample/customers.rptdocument");

// Get the root of the table of contents.
TOCNode td = document.findTOC( null );
java.util.List children = td.getChildren( );
long pNumber;
// Loop through the top level table of contents entries.
if ( children != null && children.size( ) > 0 ) {
for ( int i = 0; i < children.size( ); i++ ) {
// Find the required table of contents entry.
TOCNode child = ( TOCNode ) children.get( i );
//if ( child.getDisplayString( ).equals( "103" ) ) {
// Get the number of the page that contains the data.
pNumber = document.getPageNumber( child.getBookmark( ) );
System.out.println( child.getDisplayString( ) + "Page to print is " + pNumber );
//}
}
}

document.close();
engine.destroy();
Platform.shutdown();
System.out.println("Finished");
}

/**
* @param args
*/
public static void main(String[] args) {
try
{

Toc ex = new Toc( );
ex.runReport();

}
catch ( Exception e )
{
e.printStackTrace();
}
}

}
