countdown clock

Hi ,

I am facing in the implementation of the countdown clock add-on.

Showing that:

[size=7]

Widgetset does not contain implementation for org.vaadin.kim.countdownclock.CountdownClock. Check its @ClientWidget mapping, widgetsets GWT module description file and re-compile your widgetset. In case you have downloaded a vaadin add-on package, you might want to refer to add-on instructions. Unrendered UIDL:
-Unrendered UIDL
-org.vaadin.kim.countdownclock.CountdownClock(NO CLIENT IMPLEMENTATION FOUND) id=PID35
-countdown time=9983 format=This page will self-destruct in %s.%ts seconds.

Since I am new to vaadin development.Can I exactly know What problem I am facing ?

Most likely you haven’t compiled your widgetset after adding the jar to your application; please see instructions

Are you using Eclipse? Maven? Anyway, the key here is compiling your widgetset; the link I posted has step-by-step instructions of how you can do just that.

If you are using Eclipse without maven, you can use the Vaadin eclipse plugin to do this for you; easy as pie :slight_smile: Just select your Vaadin proiject, and press ‘compile widgetset’ (the Vaadin-like icon in the toolbar)
