I managed to save it in database, however I dont know how to get the name of button that is clicked. here is my code:

public class CommonComposer extends GenericForwardComposer{

private static final long serialVersionUID = 6848767592732520915L;
private ActivityService activityService;
private User admin;

public void doAfterCompose(Component comp) throws Exception {
    // TODO Auto-generated method stub

        activityService = (ActivityService) SpringUtil.getBean("activityService");
        admin = ContextHelper.getUser();

protected void navigateTo(String url, Map<String,Object> args, Component currentComponent){
    Component parent = currentComponent.getParent();
    Executions.createComponents(url, parent, args);

    try {
        if(!SecurityContextHolder.getContext().getAuthentication().getPrincipal().equals("anonymousUser")) {

            admin = ContextHelper.getUser();
            Activity activity = new Activity();
            activity.setDescription("User clicked url: "+url);
            activity.setCreatedDate(new Date());
            activity.setLastUpdateDate(new Date());

    } catch (NullPointerException e) {

In GenericForwardComposer, you can add an event listener on a button's id, e.g. mybutton;

public void onClick$mybutton(Event event) {

I assume the name of a button you mean is the button's id.

Hi thank you for answering my question. However my GenericForwardComposer file is read only, is there another way to add this event listerner? and how if i want to get the label of the button?

Another idea: if you need a global place to "monitor" events you can implement the ExecutionMonitor interface (especially the eventStart or eventComplete method) and configure it as a listener in your zk.xml.


and some exemplary imlementation

package my.package.example;

import org.zkoss.zk.ui.Desktop;
import org.zkoss.zk.ui.Execution;
import org.zkoss.zk.ui.event.Event;
import org.zkoss.zk.ui.event.Events;
import org.zkoss.zk.ui.util.ExecutionMonitor;
import org.zkoss.zul.Button;

public class MyExecutionMonitor implements ExecutionMonitor {
    public void executionActivate(Execution exec, Desktop desktop) {}
    public void executionWait(Execution exec, Desktop desktop) {}
    public void executionDeactivate(Execution exec, Desktop desktop) {}
    public void executionAbort(Execution exec, Desktop desktop, Throwable t) {}
    public void desktopDestroy(Desktop desktop) {}
    public void eventStart(Event event) {
        String eventName = event.getName();
        if(Events.ON_CLICK.equals(eventName)) {
            if(event.getTarget() instanceof Button) {
                Button clickedButton = (Button) event.getTarget();
                String message = String.format("%s on %s with with label %s", 
                        eventName, clickedButton, clickedButton.getLabel());
    public void eventComplete(Event event) {}
    public void eventSuspend(Event event) {}    
    public void eventResume(Event event) {}
