I created a client to communicate with RTD server, my knowledge is small in C# I have greater in JAVA, but I didn't find anything likely to be used in JAVA, I'm using this example of a C# client

using System.Linq;

using System.Threading;
using System.Runtime.InteropServices;
using System.Runtime.CompilerServices;

        static void Main(string[] args)
        {
            Console.WriteLine("Hello World!");

            chamaMetodo("RTDTrading.RTDServer");
        }

        private static void chamaMetodo(string v)
        {
                       
            RtdClient rtd = new RtdClient(v);
            Console.WriteLine("rtd:"+rtd);
            
            object[] param = new Object[2];
            param[0] = "DOLFUT_F_0";
            param[1] = "HOR";
            Object ret = rtd.GetValue(param);
            Console.WriteLine("ret:"+ret);

But I'm getting this error, in the method call:rtdServer.ConnectData(topicId, args, true);

Unhandled exception. System.Runtime.InteropServices.COMException (0x8000FFFF): Falha catastrófica (0x8000FFFF (E_UNEXPECTED))

Is anyone aware of the error?
