When you create a message flow, you include input nodes that receive messages and, optionally, output nodes that send out new or updated messages. If the processing that must be performed on the message requires it, you can include other nodes after the input node that are customized in Java to complete the actions that your applications need.
Some of the built-in nodes allow you to customize the processing that they provide. In a JavaCompute node, you can provide Java code that controls precisely the behavior of the node. This set of topics discusses how you can use Java to customize the JavaCompute node.
Use the Debug perspective to debug a message flow that contains a JavaCompute node. When control passes to a JavaCompute node during debugging, the perspective opens the Java debugger, allowing you to step through the Java class code for the node.
