如何将FOP 1.0升级到FOP 2.4-缺少org.apache.fop.apps.Driver，org.apache.fop.messaging.MessageHandler

Question

如何转换此方法/不建议使用的命名空间

import org.apache.fop.apps.Driver;
import org.apache.fop.messaging.MessageHandler;

public static void _renderPDF(ByteArrayOutputStream out, InputSource foDocument, Logger logger)
            throws IOException, FOPException {
        Driver driver = new Driver();
        driver.setLogger(logger);
        driver.setRenderer(Driver.RENDER_PDF);
        driver.setInputSource(foDocument);
        driver.setOutputStream(out);
        driver.run();
    }```
