一般都是用jacob的,这里不能发地址,自己搜一下,要下1.9的版本
1、我们解开下载的jacob_1.9.zip,在文件夹中找到jacob.dll和jacob.jar两个文件
2、将压缩包解压后,Jacob.jar添加到Libraries中;
3、将Jacob.dll放至“WINDOWS\SYSTEM32”下面。
需要注意的是:
【使用IDE启动Web服务器时,系统读取不到Jacob.dll,例如用MyEclipse启动Tomcat,就需要将dll文件copy到MyEclipse安装目录的“jre\bin”下面。
一般系统没有加载到Jacob.dll文件时,报错信息为:“java.lang.UnsatisfiedLinkError: no jacob in java.library.path”】
使用Jacob转换Word,Excel为HTML

}调用JAVA代码:
Java代码
public class Test1 {
public static void main(String[] args) {
// TODO Auto-generated method stub
TransformFiletoHtml trans = new TransformFiletoHtml();
trans.wordToHtml("D:\\sinye.doc", "D:\\sinye.html");
}
}
public class Test1 {
public static void main(String[] args) {
// TODO Auto-generated method stub
TransformFiletoHtml trans = new TransformFiletoHtml();
trans.wordToHtml("D:\\sinye.doc", "D:\\sinye.html");
}
} 只写了一个测试word转html的,excel转html的同理,在TransformFiletoHtml类中,写了两个方法,一个是删除文件夹的方法(delFolder()),一个是删除文件夹下所有文件的方法(delAllFile())。追问我是想要开始读取Excel的数据,然后在写入到html中

直接parse html 到jxl.追问能说清楚点吗??、
谢谢了。。。
追答xml reader parse html tag 所对应的element/txt type
