Add this custom Vaadin servlet to show a different favicon (other than the Vaadin default) in your UI application –
[java]
import com.vaadin.server.*;
import com.vaadin.spring.server.SpringVaadinServlet;
import org.springframework.stereotype.Component;
import javax.servlet.ServletException;
@Component(“vaadinServlet”)
public class CustomServlet extends SpringVaadinServlet {
@Override
protected void servletInitialized() throws ServletException {
super.servletInitialized();
getService().addSessionInitListener((SessionInitListener) event -> event.getSession().addBootstrapListener(new BootstrapListener() {
@Override
public void modifyBootstrapFragment(
BootstrapFragmentResponse response) {
// TODO Auto-generated method stub
}
@Override
public void modifyBootstrapPage(BootstrapPageResponse response) {
response.getDocument().head().
getElementsByAttributeValue(“rel”, “shortcut icon”).attr(“href”, “./images/favicon.png”);
response.getDocument().head()
.getElementsByAttributeValue(“rel”, “icon”)
.attr(“href”, “./images/favicon.png”);
}}
));
}
}
[/java]
