创建和修改BIRT报表是通过使用Model的接口 (org.eclipse.birt.report.model)来完成。下面是一个简单的实例：创建一个report design，添加一个label。

IDesignEngine designEngine = new DesignEngine( new DesignConfig( ) );
SessionHandle sessionHandle = designEngine.newSessionHandle( ULocale.ENGLISH );
ReportDesignHandle reportDesignHandle = sessionHandle.createDesign( );

ElementFactory elementFactory = new ElementFactory( reportDesignHandle.getModule( ) );

LabelHandle labelHandle = elementFactory.newLabel( "label" );
labelHandle.setText( "hello world" );
reportDesignHandle.getBody( ).add( labelHandle );

ModuleHandle moduleHandle = reportDesignHandle.getModuleHandle( );
moduleHandle.saveAs( path + file );
reportDesignHandle.close( );
