How to bind the java client stub and the C++ server's skeleton?

Question

hi, i'm currently working on a project which a java client invoke a C++ object.
i've wrote the idl and compile it using idl2cpp and a object is created.
then i try to compile my java client using vbjc Client. it was done without errors.
but when i try to run the client (after i run the smart agent and the C++ server) using vbj Client, it promts error which fail to load the class Client.java
and i've try to run my java client using jre (java Client), the program throws exception --> org.omg.CORBA.BAD_PARAM: minor code: 0 completed: No
so, wat's wrong with my codes actually??
it's urgent and i really need you all's help...
thanks a lot...

below is my code:
TimeObject.cpp (C++ server)
#include "TimeImpl.h"
// USE_STD_NS is a define setup by VisiBroker to use the std namespace
USE_STD_NS
int main(int argc, char* const* argv)
try {
// Initialize the ORB.
CORBA::ORB_ptr orb = CORBA::ORB_init(argc, argv);
/* // Initialize the BOA
CORBA::BOA_ptr boa = orb->BOA_init(argc, argv);
// Create the Time object
POA_Time::TimeSetting timesetting = new TimeSettingImpl("My TimeSetting");
// Export the newly created object
boa->obj_is_ready(timesetting);
// Ready to service requests
boa->impl_is_ready(); */
// get a reference to the root POA
CORBA::Object_var obj = orb->resolve_initial_references("RootPOA");
PortableServer::POA_var rootPOA = PortableServer::POA::_narrow(obj);
CORBA::PolicyList policies;
policies.length(1);
policies[(CORBA::ULong)0] = rootPOA->create_lifespan_policy(
PortableServer::PERSISTENT);
// get the POA Manager
PortableServer::POAManager_var poa_manager = rootPOA->the_POAManager();
// Create myPOA with the right policies
PortableServer::POA_var myPOA = rootPOA->create_POA("sntp_poa",
poa_manager,
policies);
// Create the servant
TimeSettingImpl timeServant;
// Decide on the ID for the servant
PortableServer::ObjectId_var managerId =
PortableServer::string_to_ObjectId("TimeManager");
// Activate the servant with the ID on myPOA
myPOA->activate_object_with_id(managerId, &timeServant);
// Activate the POA Manager
poa_manager->activate();
CORBA::Object_var reference = myPOA->servant_to_reference(&timeServant);
cout << reference << " is ready" << endl;
// Wait for incoming requests
orb->run();
catch(const CORBA::Exception& e) {
cerr << e << endl;
return 1;
return 0;
