jacob插件导出文字、表格、图片到Word
一、介绍
Jacob 是Java-COM Bridge的缩写，它在Java与微软的COM组件之间构建一座桥梁。使用Jacob自带的DLL动态链接库，并通过JNI的方式实现了在Java平台上对COM程序的调用。
二、安装和配置
Jacob是一个开源软件，它的官方站点是：http://danadler.com/jacob/ 大家可以到上面下载源代码研究，也可以直接下载编译后的二进制文件。
下载包jacob_x.x.zip，解压后有几个文件：jacob.jar、jacob.dll等
把jacob.dll拷贝到%JAVA_HOME%\jre\bin目录下，%JAVA_HOME%就是JDK的安装目录或是C:\Windows\System32下面
接着直接在java IDE中引用jacob.jar就可以使用了
三、jacob.jar的结构
jacob包括两个部分：
com.jacob.activeX: ActiveXComponent类
com.jacob.com: 其它类和元素
四、Jacob类
Jacob的结构很简单，包含以下几个类：
ActiveXComponent Class：封装了Dispatch对象，用于创建一个封装了COM组件对象的Java Object
Dispatch Class：用于指向封装后的MS数据结构。常用的方法有call，subcall，get，invoke…后面会介绍使用方法。
Variant Class：用于映射COM的Variant数据类型。提供Java和COM的数据交换。
ComException Class：异常类
五、Jacob方法
用于访问COM/DLL对象的方法，读取、修改COM/DLL对象的属性。
call method：属于Dispatch类。用于访问COM/DLL对象的方法。方法进行了重载，方便不同场合调用。返回一个Variant类型的值。
callSub method：使用方法和call一样，不过它不返回值。
get method：读取COM对象的属性值，返回一个Variant类型值。
put method：设置COM对象的属性值。
invoke method：call的另一种用法，更复杂一些。
invokesub method：subcall的另一种用法
getProperty method：属于ActiveXComponent类，读取属性值，返回一个Variant类型值。
setProperty method：属于ActiveXComponent类，设置属性值。
