为什么用ITEXT生成含汉字的pdf总是不成功，已下载itextasian.jar，并设置了CLASSPATH

E:\>javac pp.java

E:\>java pp

//writer.setPageEvent(new pdf());
找不到pdf类，所以将此句引掉。
然后执行，能够正确地生成aa.pdf。
我的环境运行环境是：jdk1.5.0。是不是jdk版本问题？

呵呵！！因为你要加载windows里面的汉字包
如：

　BaseFont bfChinese = BaseFont.createFont("../webapps/CMCS3.1/business/overDraft/SIMYOU.TTF", BaseFont.IDENTITY_H,BaseFont.NOT_EMBEDDED);
com.lowagie.text.Font FontChinese = new com.lowagie.text.Font(bfChinese, 12, com.lowagie.text.Font.NORMAL);

SIMYOU.TTF这个文件在windows的系统目录中可以找到的，

请问,如果是要读取日文的pdf,怎么实现呢?用pdfbox怎么实现呢?或者用itext(亚洲)怎么实现呢?

[yingti_anxia]

我也遇到了这个问题，pdf中不知道该怎么样插入中文汉字？yyttrr2006你解决这个问题了么？给我讲讲吧，QQ:724380361

打开BaseFont类你会发现
public static final String RESOURCE_PATH = "com/itextpdf/text/pdf/fonts/";
但是在iTextAsian.jar里你会发现 iTextAsian的包名是 "com.itextpdf.text.pdf.fonts"程序在加载的过程中会根据 RESOURCE_PATH的路径去寻找下面的peoperties文件,它的font和encoding文件都是从String RESOURCE_PATH = "com/itextpdf/text/pdf/fonts/"; 这里加载的,而老itextasian.jar的包名是com.lowagie.text.pdf.fonts, 应该是包名重新命名了, 而没有及时更新itextasian.jar, 改了一下itextasian.jar包路径, 重新运行程序, OK, 搞定.
更改iTextAsian.jar包名的方法如下
1)使用winrar解压缩程序将原来的iTextAsian.jar解压，目录结构如下
iTextAsian
--com
--lowagie
--text
--pdf
--fonts
--...(字体属性文件)
2)将加压后com目录下的包名lowagie更改为itextpdf
3)在命令行转至iTextAsian目录，重新打包为iTextAsian.jar文件
命令如下：
jar cvf iTextAsian.jar .
