How to connect to a MQ server on the fly in 6.1

In our project there is need for us to connect to IBM MQ on the fly to, deliver documents to MQ.
The MQ credentials like Queue Name, user id password word would be supplied to the service.
I am unable to locate the putService for using it at the runtime.
At present, we are creating adapters through the interfacing and calling the adapters. However we wish to create the adapter on the fly and pass the credentials to the service.
In 4.6 There is a service under MQSeries package which has the necessary putQ utility service but in 6.1 I am unable to locate one.
Please let me know if anyone has designed a similar service before.
