Developing Extensions

Hello everyone!

I wondered about how to develop extensions for my application. Is there an example about how to use JPF together with vaadin or is there an easier approach? The best solution would be to enable and disable the plugins on the fly.

Thanks in advance,
Heinz

Hello again,

maybe I should be more concrete: Let's think about an Basic Application:

package com.example.demo;

import com.vaadin.Application;
import com.vaadin.ui.*;

public class DemoApplication extends Application {
	private static final long serialVersionUID = 1L;

	@Override
	public void init() {
		Window mainWindow = new Window("Demo Application");
		Label label = new Label("Hello Vaadin user");
		mainWindow.addComponent(label);
		setMainWindow(mainWindow);
	}
}

Now I want to load all *.jar-Files in a folder (e.g. WebContent/WEB-INF/plugins) and call a method of a class, that implements a special interface.

How could I do this?

Thanks in advance!

See here for some pointers and code.

Thanks, Mathias!

I will try this!
