Steps i followed are:

  1. Adding in DBarDemoWidgetset.gwt.gwt.xml
    2)Launch the code server with “org.vaadin.alump.distributionbar.demo.widgetset.DBarDemoWidgetset”
    3)Launch application on tomcat
    4)Open application http://localhost:8080/DistributionBarDemo/?superdevmode

Please let me know if i am missing anything.
I tried to run the demo application of addon ‘distribution-bar’ i,e (dbbar-demo)

Below is the link of source code of the addon https://github.com/alump/VaadinDistributionBar

Any hints on this is greatly appreciated :slight_smile:
