Jacob - ocx

Jacob 调用OCX 方式：jacob-1.18

为了避免出现问题，环境如下：

1、JDK1.7 32bit  .eclipse的jre版本要和jdk一致，window->preferences->java->compiler勾选jdk 1.7  build path  配置成jdk1.7版本.

2、在项目目录下新建lib目录，将jacob.jar文件拷贝到该目录下，点build path->configbuild path ->libraries。

备注：1.jacob.jar不要放到jdk的目录下，可能有冲突

2.jacob.dll经测试放在..\jdk1.6.0_22\jre\bin下被成功引用，其他目录建议不放，防止出现奇葩问题，

如果需要知道你的ocx控件注册后的CLSID,可以在注册表中搜索得出:
假设我的控件名称是abc.ocx,
打开注册表:运行regedit
Ctrl+F打开查找对话框,查找abc.ocx,会展开一个目录类似:{A71B53F3-562C-451E-9F92-DCF5B8852B6E}
这个目录名即是CLSID.
