IText生成doc文档需要三个包：iTextAsian.jar，iText-rtf-2.1.4.jar，iText-2.1.4.jar

亲测无误，代码如下：

import com.lowagie.text.*;import com.lowagie.text.Rectangle;import com.lowagie.text.rtf.RtfWriter2;import java.io.FileOutputStream;/** * 纸张方向横向测试 * User: HYY * Date: 13-8-1 * Time: 下午9:54 * To change this template use File | Settings | File Templates. */public class RotatePageTest {      public static void main(String[] args) throws Exception {        //设置纸张的大小对象        Rectangle rectangle = new Rectangle(PageSize.A4);        // 创建word文档,并旋转，使其横向        Document document = new Document(rectangle.rotate());        RtfWriter2.getInstance(document, new FileOutputStream("C:/無幽之路IText教程.doc"));        document.open();        document.close();    }}
