java - jni4net - System.Runtime.Remoting.RemotingException

Question

我正在尝试使用 Java/.NET 桥接器与服务器通信。这座桥是用jni4net build 的并且似乎有效(到目前为止)。

  public static void main(String[] args) {
    File sibDll = new File("SibKernel.Client.j4n.dll");

    Bridge.setVerbose(true);
    Bridge.setClrVersion("v20");    

    try {
      Bridge.init();

      Bridge.LoadAndRegisterAssemblyFrom(sibDll);

    } catch (IOException e) {
      e.printStackTrace();
    }

    if (SibKernelHelper.isConfigured() == false) {
      SibKernelHelper.Configure();
    }

    IMasterBoardManager mstrBoardMngr = SibKernelHelper.GetMasterBoardManager();
  }

我真的不知道问题出在哪里。有没有人遇到过这样的问题？

这是完整的异常堆栈跟踪:

Answer 1

您似乎正在尝试实例化某些继承或依赖于 jni4net 的类型，但问题发生在您的 .NET 远程处理的另一端。 可能您将 Java 对象的实例作为远程调用的参数传递。
