In my Vaadin Flow 24 application, I have a view:
@Route(value = "embedded/jobables/recent")
@AnonymousAllowed
public class RecentJobablesEmbeddedView extends VerticalLayout implements HasUrlParameter<String> {
...
}
which is also component(extended from VerticalLayout).
I'd like to export this component to be able to embed it into non-Vaadin HTML page.
I created the following exporter class:
public class RecentJobablesEmbeddedExporter extends WebComponentExporter<RecentJobablesEmbeddedView> {
protected RecentJobablesEmbeddedExporter(String tag) {
super("recent-jobables-embedded-view");
}
@Override
protected void configureInstance(WebComponent<RecentJobablesEmbeddedView> webComponent, RecentJobablesEmbeddedView recentJobablesEmbeddedView) {
}
}
Right now I'm unable to access:
http://localhost:8080/vaadin/web-component/recent-jobables-embedded-view.js
Vaadin flow application returns 404 Page Not Found.
What am I doing wrong and how to fix it?
The WebComponentExporter implementation must have a public default constructor. In your sample code, it is protected and it takes an argument.
If you check the server logs, you should see a message like
Class RecentJobablesEmbeddedExporter has no public no-argument constructor, and won't be instantiated as a 'WebComponentExporter' by default
