How to pass the queue name dynamically to MQ Adapter

Requirement: To pass the queue name dynamically to MQ Adapter from a variable

Use-case: I have a process that is required to enqueue the data in one of the two MQs at runtime based on certain condition using single MQ Adapter. So if the condition is true the data is to be enqueued in queue A else in queue B. However, the payload schema remains the same in both the queues. (using SOA Suite

Solution: Use the property appearing in the Properties tab of Invoke Activity. Assign the value of the property to the variable name which contains the MQ name.
Passing Queue Name from a variable

Setting the value to this variable will allow you to set the queue name dynamically in the process or from outside the process.

Advantage: MQ Adapter can be loosely coupled and kept in a separate composite which can be called by any caller composite. Also a single MQ Adapter can be used for en-queuing to multiple queues.
