We modify the Makefile for this component:

title	jHelloComponent/src/Makefile

...
JARFILES = HelloComponentImpl
HelloComponentImpl_DIRS = acsws
...

We fill the component code as follows:

language	java
title	jHelloComponent/src/acsws/workshop/HelloComponentImpl/HelloComponentImpl.java
linenumbers	true

//Suggested: import alma.<Module>.<Interface>Impl; //But anything, really
package acsws.workshop.HelloComponentImpl;
 
//Base component implementation, including container services and component lifecycle infrastructure
import alma.acs.component.ComponentImplBase;
 
//Skeleton interface for server implementation
import acsws.workshop.HelloComponentOperations;


//ClassName usually is <Interface>Impl, but can be anything
public class HelloComponentImpl extends ComponentImplBase implements HelloComponentOperations {
    public HelloComponent() {
    }
    public void printHello() {
        System.out.println("Just printing 'Hello World!'");
    }
}
