When you use the JavaCompute node, you customize it to determine the exact processing that it provides.
To tailor the behavior of each node, create a Java™ class file that provides the processing that you want. You manage Java files through the Java perspective.
The Java user-defined node API includes some extra methods that simplify tasks that involve message routing and transformation. These tasks include accessing named elements in a message tree, setting their values, and creating elements, without the need to navigate the tree explicitly.
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, and you can step through the Java class code for the node.
