jms producer send() method

[Rizwan Mohammad]

Hi, When we send jms message from JMS producer (client) to IBM MQ (JMS provider) , do we need any kind of acknowledgement from MQ Broker saying that it has received the message. Or if send() is successful, can I assume or is it guarantee that it has reached the provider. Is it mentioned somewhere in JMS specification? Anyway, I dont mind whether consumers consumed it or not. My interest is knowing only in sending message to provider. With successful send() method invocation, is it guranteed? Please advice
