Hi all,
When I try to run this code (below), it gives an error. I could not find
the reason. Could you please help me.
Onder.
Error;
org.eclipse.birt.report.model.metadata.ExtensionLoader
logExtenstionException
[java] SEVERE: Message:The extension point
[org.eclipse.birt.report.model.reportItemModel] is not found. Error
code:EXTENSION_POINT_NOT_FOUND
My code (which I have taken from eclipse site - dedemo.java)
// Create a session handle. This is used to manage all open designs.
// Your app need create the session only once.
SessionHandle session = DesignEngine.newSession( null );
// Create a new report design.
ReportDesignHandle design = session.createDesign( );
// The element factory creates instances of the various BIRT elements.
ElementFactory factory = design.getElementFactory( );
// Create a simple master page that describes how the report will
// appear when printed.
//
// Note: The report will fail to load in the BIRT designer
// unless you create a master page.
DesignElementHandle element = factory.newSimpleMasterPage( "Page Master"
); //$NON-NLS-1$
design.getMasterPages( ).add( element );
// Create a grid and add it to the "body" slot of the report
// design.
GridHandle grid = factory.newGridItem( null, 2 /* cols */, 1 /* row */ );
design.getBody( ).add( grid );
// Note: Set the table width to 100% to prevent the label
// from appearing too narrow in the layout view.
grid.setWidth( "100%" ); //$NON-NLS-1$
// Get the first row.
RowHandle row = (RowHandle) grid.getRows( ).get( 0 );
// Create an image and add it to the first cell.
ImageHandle image = factory.newImage( null );
CellHandle cell = (CellHandle) row.getCells( ).get( 0 );
cell.getContent( ).add( image );
image.setURI( "http://www.eclipse.org/birt/tutorial/multichip-4.jpg" );
//$NON-NLS-1$
// Create a label and add it to the second cell.
LabelHandle label = factory.newLabel( null );
cell = (CellHandle) row.getCells( ).get( 1 );
cell.getContent( ).add( label );
label.setText( "Hello, world!" ); //$NON-NLS-1$
// Save the design and close it.
design.saveAs( "sample.rptdesign" ); //$NON-NLS-1$
design.close( );
// We're done!
I think it is about a .jar (which jar ?)
Regards,
Onder.

Onder,
BIRT_HOME should be set to 1.
There is no relation between 1 and 2.
Just set BIRT_HOME to C:\birtruntime\birt-runtime-2_0_1\Report Engine.
You do not have to set any other variable.
Here is an example. In this example I set BIRT_HOME by just creating an
EngineConfig class. It is probably better to have as an Environ variable
though.
