Birt的创建步骤
1.创建designEngine
DesignConfig config = null;
try{
config = new DesignConfig( );
IDesignEngineFactory factory = (IDesignEngineFactory) Platform
.createFactoryObject( IDesignEngineFactory.EXTENSION_DESIGN_ENGINE_FACTORY );

IDesignEngine engine = factory.createDesignEngine( config );
}catch( Exception ex){
ex.printStackTrace();
}

2.创建ElementFactory SessionHandle session = null;
ReportDesignHandle designHandle;
ElementFactory efactory = null;
try {
session = engine.newSessionHandle(ULocale.CHINESE);// .ENGLISH ) ;
designHandle = session.createDesign();
efactory = designHandle.getElementFactory();
} catch (Exception e) {
e.printStackTrace();
}

之后也可创建：dataSource,dataSet

3.创建一个master PageDesignElementHandle simpleMasterPage = efactory.newSimpleMasterPage( "Master Page" );
designHandle.getMasterPages( ).add( simpleMasterPage );
designHandle.saveAs(filePath);

4.关闭 report
designHandle.saveAs(filepath);
designHandle.close( );
