Question

我有一个非常简单的CORBA代码。它有一个简单的例程可以将消息写入文件。如果我手动启动服务器，代码运行正常。输出文件将按预期创建。如果我添加服务器到IMR并让IMR负责启动，代码不会写出out文件。有人能告诉我发生了什么以及如何解决它吗？

void
Hello_impl::say_hello() throw (CORBA::SystemException)
{
   cout << "Hello World" << endl;
   char* msg = strdup ("Hello from this world to the next");

   ofstream out;
   out.open ("./mydata2.txt", std::ios::out);
   out << msg;
   out.close();
}

这是服务器代码。

run (CORBA::ORB_ptr orb)
{
   CORBA::Object_var poaObj =
      orb->resolve_initial_references("RootPOA");

   PortableServer::POA_var rootPoa =
      PortableServer::POA::_narrow(poaObj);

   PortableServer::POAManager_var manager =
      rootPoa->the_POAManager();

   CORBA::PolicyList policyList(2);
   policyList.length(2);

   policyList[0] = rootPoa->create_lifespan_policy(
      PortableServer::PERSISTENT);

   policyList[1] = rootPoa->create_id_assignment_policy(
      PortableServer::USER_ID);

   PortableServer::POA_var helloPOA =
      rootPoa->create_POA ("hello", manager, policyList);

   CORBA::PolicyList policyList;

   PortableServer::POA_var helloPOA =
      rootPoa->create_POA ("hello", manager, policyList);

   Hello_impl* helloImpl = new Hello_impl(helloPOA);
   PortableServer::ServantBase_var servant = helloImpl;

   PortableServer::ObjectId_var oid =
      PortableServer::string_to_ObjectId("hello");

   helloPOA->activate_object_with_id (oid, servant);
   Hello_var hello = helloImpl->_this();

   CORBA::String_var s = orb->object_to_string(hello);
   const char* refFile = "/tmp/Hello.ref";
   ofstream out (refFile);
   out << s << endl;
   out.close();
}

在IMR下运行服务器时未创建输出文件
