You can define the behavior of a node of type node suing the Action element. This Action is executed when the process arrives to the node.

The Action to be executed can be defined in two ways:

• Using a BeanShell script.
• Using an action handler, this is a Java class which implements the ActionHandler interface.

Below we are going to create a sample process with a node node which make use of an implementation of the ActionHandler interface.

In this image you can see the process definition graph:

This process begins in a start node and go to a node node where the action to be performed is defined by the class MyAction which implements the ActionHandler interface.

public class MyAction implements ActionHandler {
  @Override
  public void execute(ExecutionContext executionContext) throws Exception {
    System.out.println("Executing programmed action...");

    // Go to next node
    executionContext.getProcessInstance().signal();
  }
}
