关于jacob中出现的问题（上传文件）
1) 把jacob.dll放入 Java\jdk1.5.0_06\jre\bin目录下.
2) 把jacob.jar放入 Java\jdk1.5.0_06\jre\lib\ext 目录下.
3) 运行*.java即可编译通过.
注明：
1)配置后不需要再进行什么环境变量path,classpath的设置.
2)jdk版本高于1.4.2就不会影响程序，低于其以下没测试.
常见错误解释：
------------
1、找不到jacob.dll，配置路径问题（确认jacob.dll配置正确）
Exception in thread "……" java.lang.UnsatisfiedLinkError: no jacob in java.library.path
at java.lang.ClassLoader.loadLibrary(ClassLoader.java:1682)
at java.lang.Runtime.loadLibrary0(Runtime.java:822)

2、找不到资源文件，资源文件路径问题（查看程序中资源文件路径的设置，并检查资源文件的存放路径）
Exception in thread "……" com.jacob.com.ComFailException: Invoke of: Open

3、jacob.dll或jacob.jar对应版本错误
com.jacob.com.ComFailException: A COM exception has been encountered:

jacob 就是 JAVA-COM Bridge的缩写，它是在java与微软的com组件之间的桥梁，通过使用jacob自带的dll动态链接库通过JNI的方式实现了在sun java平台上的程序对com调用。
