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)
            at java.lang.System.loadLibrary(System.java:992)
            at com.jacob.com.Dispatch.<clinit>(Dispatch.java:36)
            ……
            at java.awt.EventDispatchThread.run(EventDispatchThread.java:110)
    
    ------------
    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
    Source: Microsoft Word
    Description: RCHITECTURE=x86
            at com.jacob.com.Dispatch.invokev(Native Method)

            at com.jacob.com.Dispatch.call(Dispatch.java:606)
            at WordControl.openDocument(Test06_08_01.java:3027)

            at java.awt.EventDispatchThread.run(EventDispatchThread.java:110)
    
    ------------
    3、jacob.dll或jacob.jar对应版本错误
    com.jacob.com.ComFailException: A COM exception has been encountered:
    At Invoke of: Documents
    Description: An unknown COM error has occured.
    at com.jacob.com.Dispatch.invokev(Native Method)

    com.jacob.com.ComFailException: A COM exception has been encountered:
    At Invoke of: Quit
    Description: An unknown COM error has occured.

    Exception in thread "main"

    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。
