com.jacob.activeX: ActiveXComponent类
com.jacob.com: 其它类和元素

ActiveXComponent：封装了Dispatch对象，用于创建一个封装了COM组件对象的Java Object
Dispatch：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：用于映射COM的Variant数据类型。提供Java和COM的数据交换。
ComException：异常类

call：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：使用方法和call一样，不过它不返回值。
get：读取COM对象的属性值，返回一个Variant类型值。
put：设置COM对象的属性值。
invoke：call的另一种用法，更复杂一些。
invokesub：subcall的另一种用法
getProperty：属于ActiveXComponent类，读取属性值，返回一个Variant类型值。
setProperty：属于ActiveXComponent类，设置属性值。
setProperty：属于ActiveXComponent类，设置属性值
