Hi everybody,
I’m developing a chart project. I downloaded the invient chart source codes and compiled the widget sets with GWT compiler.
My project is a maven project. I don’t have WebContent directory. Where will I put compiled widgetsets to my project? Please help meeeee…
Thankss…
I have mine in src/main/webapp/VAADIN.
Hi,
regarding the error message stated in the topic title - I would advise you to double check that you have added the
<inherits name="com.invient.vaadin.charts.widgetset.InvientChartsWidgetset"/>
in your widgetset descriptor.

Thanks to everybody.
I solved this issue finally 
Please let me explain how did I do.
Download the source code from this link: https://vaadin.com/directory#addon/invient-charts and then export files to any folder.
Download GWT compiler files “gwt-2.5.0.zip” (Just search from google) and export it any folder.
Install these plugins to eclipse: GWT Designer Core, GWT Designer Editor, GWT Designer GPE
Create a new project from this way: File - New Project - Google - Web Application Project (My project name is MyInvientCharts)
Import this folder “InvientCharts-master/src/com/invient/vaadin/charts” to project’s “src” folder.
Now create a folder “gwt” and then import gwt-2.5.0/*.jar files
Right click to MyInvientCharts project - Properties - Java Build Path - Add Class Folder - Choose gwt folder in your project. Click OK.
SELECT this file: MyInvientCharts/src/com/invient/vaadin/charts/widgetset/InvientChartsWidgetset.gwt.xml
Be sure this file contains this line:
Now click to “Compile Vaadin widgets (Ctrl + 6)” button from toolbar. And then wait a minute while eclipse compiles the widgetset.
(KEY OPERATION) Compiled widgetset files are placed to WebContent/VAADIN/widgetsets/com.invient.vaadin.charts.widgetset.InvientChartsWidgetset and copy this to your real project’s src/main/webapp/VAADIN/widgetsets/ folder.
Create a class which extends NavigableApplicationServlet and put these methods:

Put your javascipt files to src/main/webapp/VAADIN/themes/myRealProjectTheme/js/
now you can run your project with this command:
mvn clean package jetty:run
I hope explain my solution If you have a question about this issue please add comment. I try to help you…
