Flex实现在线显示Word文档,FlexPaper_JAVA_编程开发_程序员俱乐部

思想:生成Word->pdf->swf->flexpaper显示.oh ,my god!
用开源Itext.jar生成Word文档;
通过开源jacob.jar实现Word转换成PDF;
通过软件Pdf2Swf转换PDF成Swf文件;
通过开源FlexPaper.swf组件显示Swf文件.
(有点繁琐,但是我没找到解决的办法,貌似有个OpenOffice,但是收费...)

class="java">
// 第一步：创建一个document对象。
Document document = new Document(PageSize.A4);
// 第二步：将文件输出流指向一个文件。
RtfWriter2.getInstance(document, new FileOutputStream("C:\\mmmmm.doc"));
// 第三步：打开文档。
document.open();
//字体
Font font =  new Font(Font.NORMAL, 14,Font.BOLD, new Color(0, 0, 0));
// 第四步：在文档中增加一个段落。
Paragraph paragraph = new Paragraph("xxxxxxxxxxxxx", font);
paragraph .setAlignment(Element.ALIGN_CENTER);
document.add(paragraph );
// 第五步：关闭文档。
document.close();
