Completing a to-do task for converting a function selector

Configure a JavaCompute node named SelectFunction.

1. In IBM Integration Toolkit, open the subflow that contains the JavaCompute node function selector.
2. If necessary, reorder the nodes. Right-click the canvas, select Layout, and choose a layout.
3. Double-click the JavaCompute node ( called SelectFunction) to edit it.
   The node contains code similar to the following snippet:

   
        // TODO: The Export_MQ Export selects from the available interface operations 
        // using the following function selector:
        // com.ibm.websphere.sca.mq.selector.impl.Constant
        // 
        // Manually convert the function selector here to select one of the 
        // available operations:
        // callHello, callGoodbye, callAuRevoir 			
        String selectedFunction = "callHello";
        
        // Finally, set the selected operation into the labelName element 
        DestinationData.createElementAsFirstChild(MbElement.TYPE_NAME_VALUE, "labelName", selectedFunction);
   

   The available functions are taken from the mediation module, and your code might differ from this example. The string selectedFunction is hard-coded to the first function in the list of functions from the mediation flow.
4. Write code that replicates the actions of the function selector in the mediation module, to select one of the available operations.
   For example, you might look in the message for a particular transport header.
