ORA-32162: Read/Write SQL method not registered-for OTT

Question

I am trying this--
env = Environment::createEnvironment (Environment::OBJECT);
RegisterClasses(env);
conn = env->createConnection (user, passwd, db);
RegisterClasses is my mapping function; But still I am getting this error at--
stmt->registerOutParam( 2,OCCIPOBJECT);
I am trying to make a stored procedure call here...
Can anyone tell me what is that I am missing?

Hi,
I am using OTT generated objects to pass them to my PL/SQL procedures as OUT parameters. When I call the registerOutParam() function, I get this error ORA-32162: Read/Write SQL method not registered.
I am calling my mapping function after creating environment and before creating my stateless connection pool. But still I am getting this exception at runtime while calling registerOutParam().
Environment* env;
env = Environment::createEnvironment(Environment::OBJECT);
MessageTOMapping(env); // Calling the mapping function here.
// Creating the stateless connection pool.
StatelessConnectionPool* scp;
scp = env->createStatelessConnectionPool("naveen",
"naveen",
"//10.105.153.11:1521/pls",
10,
5,
2,
StatelessConnectionPool::HOMOGENEOUS);
// Fetch a connection from the stateless connection pool
conn = scp->getConnection();
// After this, I create my Statement and call the registerOutParam() which
// causes ORA-32162 exception.
Please note that I do not get this error when I don't use any connection-pooling mechanism. That is, if I create an environment in OBJECT mode, call the mapping function with its pointer and create a normal Connection object (without any pooling etc), my application runs perfectly fine. E.g. if I replace the above piece of code with the code below, my application runs fine.
Environment* env;
env = Environment::createEnvironment(Environment::OBJECT);
MessageTOMapping(env); // Calling the mapping function here.
conn = env->createConnection("naveen", "naveen", "//10.105.153.11:1521/pls");
// After this, I create my Statement and call the registerOutParam() which
// does not give problem now and my application runs pefectly fine.
Can anyone let me know what I am doing wrong while using the stateless connection pooling mechanism? I definitely need to use Stateless Connection Pooling and must not get connections directly from env->createConnection().
Any help will be greatly appreciated.
Thanks and Regards,
Naveen
