Hi Ivy Team, I'm managing to create a custom tag in JSF. But it seems not work. Do I need to do something more ?

This is my custom class

@FacesComponent(createTag = true, tagName = "helloComponent", namespace = "http://example.com/tags")
public class HelloComponent extends UIComponentBase {
  public String getFamily() {
      return "Greeting";
  public void encodeBegin(FacesContext context) throws IOException {
      String message = (String) getAttributes().get("message");
      ResponseWriter writer = context.getResponseWriter();
      writer.startElement("p", this);
      writer.write("Messageeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee: " + message);


This is my xhtml view : alt text

hi @tdtin Did you create jar lib and put to WEB-INF/libs folder? https://answers.axonivy.com/questions/3488/support-for-facescomponent-within-an-axon-ivy-project-without-putting-jars-into-ivy-web-inf-lib ?

Hi @IvyTeam Is there any way that we can see ivy get trouble when loading lib from that folder? May be the lib have something wrong. Thanks

Hi @Alex Suter, I couldn't find Java FacesComponent Demo in Html dialog demos, can you provide any hint ?

Well i am not aware if there any troubleshooting methods at the moment. But I don't recommend to go that way, when you still have to put things in ivy/web/lib. Releasing will be hard.

To use the component 2 things are required:

  1. the component must be accessible by the tomcat webapp-classloader: so the compiled class must either:
    • be copied as .class into webapps/ivy/WEB-INF/classes
    • be copied as .jar into webapps/ivy/WEB-INF/libs
  2. furthermore the component must be registered in the webapps/ivy/WEB-INF/faces-config.xml. You will see that our own IvyComponent is also registered there:

    <component> <component-type>IvyComponent</component-type> <component-class>ch.ivyteam.ivy.dialog.execution.jsf.component.IvyCompositeComponent</component-class> </component>

And yes the approach has some limitations:

  • components must be part of your deployment process. So you should have an automated deployment chain with scripts that also deploy and register this component during project deployments.
  • designer requires a full restart before changes in faces-config.xml or changes in compile jar/classes are in effect.
