使用utgard调用OPC时出现如下异常：

解决方法如图

maven依赖：

测试代码：

public static void main(String[] args)throws Exception{
    ConnectionInformation ci = new ConnectionInformation();
    ci.setHost("192.168.0.210");
    ci.setDomain("");
    ci.setUser("admin");
    ci.setPassword("123456");
    ci.setClsid("2461FC68-1D4E-11D1-A34D-00A024CDD5E5");
    ci.setClsid("2461FC68-1D4E-11D1-A34D-00A024CDD5E5");
    Server server = new Server(ci,Executors.newSingleThreadScheduledExecutor());
    server.connect();

    //或以下获取OPCEnum方法

        ServerList serverList = new ServerList("192.168.0.210","Administrator","123456","");
        Collection<ClassDetails> classDetails = serverList
                .listServersWithDetails(new Category[] {
                        Categories.OPCDAServer10, Categories.OPCDAServer20,
                        Categories.OPCDAServer30 }, new Category[] {});
        for (ClassDetails cds : classDetails) {
            System.out.println(cds.getProgId() + "=" + cds.getDescription());
        }
    }
