java opc

使用utgard ,网址：http://openscada.org/projects/utgard/，
utgard 下载地址：http://download.openscada.org/utgard/I/1.2.0/
需要依赖包：j-Interop, 地址： http://j-interop.sourceforge.net/
下载地址：https://jaist.dl.sourceforge.net/project/j-interop/j-interop/j-Interop%203.0/j-Interop_3_0_0.tar.gz

依赖包slf4j：slf4j-api-1.7.7.jar log4j-1.2.17.jar

运行需要7个jar ,分别是:j-Interop三个, slf4j两个,utgrad两个。
