Javajet Sample to Get List of Routines in a Talend Custom Component

This .javajet program uses the static class RoutinesUtil to retrieve a list of System Routines loaded in Talend Open Studio.

The class RoutinesUtil is not available at runtime, so this example loops within the code generation context.  The org.talend.core classes aren't found when the component runs, but are available when the Java code is generated.

This is taken from a Begin Javajet.  During the codegen phase, the getCurrentSystemRoutines() method is called and generates a System.out.println() statement for each System Routine.
