I am attempting to connect to ActiveMQ Artemis using AMQP 1.0 protocol using
Apache Qpid-Proton library; I'm using its C++ binding.
After I connect to Artemis my client gets disconnected throwing the
exception
> amqp:internal-error: Unrecoverable error: NullPointerException
on running the `on_connection_open` method.
In the Artemis console I had observed that after successfully executing
`on_container_start` method; in the `Connection` tab a new connection entry
is inserted with all proper values. Executing `on_connection_open` method
return exception.
//is a static method
bool MessageQueue::initalize_message_queue(void)
{
try {
proton::container(mq).run();
return true;
}
catch (const std::exception& ex) {
#ifdef _DEBUG
spdlog::error("Exception in
MessageQueue::initalize_message_queue.
Exception : {}", ex.what());
#endif // _DEBUG
LOG_ERROR << ex.what();
return false;
}
}
void MessageQueue::on_container_start(proton::container& container)
{
try {
proton::connection_options connection_option;
if (not this->user_name.empty())
connection_option.user(this->user_name);
if (not this->password.empty())
connection_option.password(this->password);
connection_option.sasl_enabled(false);
container.connect(this->broker_uri, connection_option);
}
catch (const std::exception& ex) {
#ifdef _DEBUG
spdlog::error("Exception in MessageQueue::on_container_start.
Exception : {}", ex.what());
#endif // _DEBUG
LOG_ERROR << ex.what();
}
}
void MessageQueue::on_connection_open(proton::connection& conn)
{
try {
conn.open_receiver(this->endpoint);
conn.open_sender(this->endpoint);
}
catch (const std::exception& ex) {
#ifdef _DEBUG
spdlog::error("Exception in MessageQueue::on_connection_open.
Exception : {}", ex.what());
#endif // _DEBUG
LOG_ERROR << ex.what();
}
}
// **I am receiving error here**
void MessageQueue::on_connection_error(proton::connection &connection)
{
#ifdef _DEBUG
spdlog::error("Caught Error in MessageQueue::on_connection_error. Error
: {}", connection.error().what());
#endif // _DEBUG
LOG_ERROR << connection.error().what();
}
Error Output :
Caught Error in MessageQueue::on_connection_error. Error :
amqp:internal-error: Unrecoverable error: NullPointerException
As per my knowledge NullPointerException belong to languages operating on
JVM or any such runtime engine. It is not something native to C++.
