Hello,
I'm trying to generate a Gantt chart with BIRT DE 3.7.1, I started with this tutorial:
www.birt-exchange.org/org/devshare/designing-birt-reports/1420-java-example-of-createing-a-report-with-a-gantt-chart/
and I've made some changes: I've established a connection to a MySQL Database and I'm trying to generate my own Gantt char.
The problem is when I run my report I get no errors but I get a white page instead of may chart
Here is my code:

I am not sure this is the issue but you should not be setting a birt home:
config.setBIRTHome("C:/K/ReportEngine");
Remove that line. Also try changing your buildDataSet to the following:
void buildDataSet( ) throws SemanticException
{
OdaDataSetHandle dsHandle = elementFactory.newOdaDataSet( dataSetName,
"org.eclipse.birt.report.data.oda.jdbc.JdbcSelectDataSet" );
dsHandle.setDataSource( "Data Source" );
//String qry = "Select PRODUCTCODE, QUANTITYORDERED from orderdetails
where ordernumber = 10104";
String qry = "Select NomTache, Debut, Fin from gantt";
dsHandle.setQueryText( qry );
OdaResultSetColumn column = StructureFactory.createOdaResultSetColumn( );
column.setNativeName( "NomTache" );
column.setColumnName( "NomTache" );
OdaResultSetColumnHandle columnHandle = (OdaResultSetColumnHandle) dsHandle
.getPropertyHandle( OdaDataSetHandle.RESULT_SET_PROP ).addItem(
column );
OdaResultSetColumn column2 = StructureFactory.createOdaResultSetColumn( );
column2.setNativeName( "Debut" );
column2.setColumnName( "Debut" );
OdaResultSetColumnHandle columnHandle2 = (OdaResultSetColumnHandle) dsHandle
.getPropertyHandle( OdaDataSetHandle.RESULT_SET_PROP ).addItem(
column2 );
OdaResultSetColumn column3 = StructureFactory.createOdaResultSetColumn( );
column3.setNativeName( "Fin" );
column3.setColumnName( "Fin" );
OdaResultSetColumnHandle columnHandle3 = (OdaResultSetColumnHandle) dsHandle
.getPropertyHandle( OdaDataSetHandle.RESULT_SET_PROP ).addItem(
column3 );
reportDesignHandle.getDataSets( ).add( dsHandle );
}
Finally after you run it, if the error persists, switch to the xml view
and look on the left margin for the red circle that indicates an error.

Can you try this report:
http://www.birt-exchange.org/org/devshare/designing-birt-reports/1471-de-api-gantt-report-from-sample-db/
Remove the OdaResultSetColumn fields:
OdaResultSetColumn column = StructureFactory.createOdaResultSetColumn( );
column.setNativeName( "NomTache" );
column.setColumnName( "NomTache" );
OdaResultSetColumnHandle columnHandle = (OdaResultSetColumnHandle) dsHandle
.getPropertyHandle( OdaDataSetHandle.RESULT_SET_PROP ).addItem(
column );
When your report is created open it in the designer and try to preview
the data set. Does it work? If you can create the same report in the
designer and get it working post that design and the design that your
api code creates.
