Developing Java™ projects using a .java file
You develop Java projects using the Java perspective workbench.
You can add any valid Java code to a JavaCompute node, making full use of the Java user-defined node API to process an incoming message. You can use the Java editing facilities of the Eclipse platform to develop your Java code.
If you have selected a user-defined message node, you have access to various resources that include the .java file; this file includes Java source code for Property Editors and Compilers.
You can also call Java methods directly from the Mapping node.
