Vaadin Chart Add-on Widget set is not compiling

Nanda3 · February 25, 2013, 1:33pm

I am trying to implement vaadin chart add-on in my vaadin project. But the GWT widget set is not compiling. Instead, its throwing an error.
I have downloaded the latest vaadin-charts-1.0.0 jar file. Please tell me whats the problem.
I am writing both the error message and my code below. Please go through it.

This is the error I am getting when i compile the client side widget set:

Hi,

It looks to me that you are trying to use Vaadin Charts with Vaadin 6. At least currently Vaadin Charts only supports Vaadin 7.

cheers,
matti

Nanda3 · February 26, 2013, 11:43am

Thank you for the suggestions Matti.
I have downloaded Vaadin 7 and Modified my code according the Vaadin 7 flow (i.e Like replacing Application with UI class).
But still its not working for me. I am getting HTTP Status 500 error.
I am giving my code and the console-error down here. Also Im attaching a screen shot of the Eclipse IDE that I am working with. Please go through it and give me some suggestions.
Thank you,

Hi,

The class not found error for missing IOUtils would sound like you don’t have correct dependencies set in your project. You’ll need commos-io and gson library because of Charts. Easy method to get proper control for your dependencies is to use a sane
project management system
. Else you’ll need to manually add those libraries to your projects class path (WEB-INF/lib). Check out the README in the package for more details.

cheers,
matti

Nanda3 · March 1, 2013, 1:31pm

Thanks for the suggestions.
I have done everything as instructed, but still its not working.
This time its compiling properly.
I have added all the libraries like common-io, gson etc. I tried setting the dependency in ivy.xml also.
When I run the application the browser displays -
" Widgetset does not contain implementation for com.vaadin.addon.charts.Chart. Check its component connector’s @Connect 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."

The console text is like this :

Hi…I have finally got the answer…
Its was a simple mistake :*), I didnt compile the add-on widget properly.
I thought the widget set gets compiled automatically, but no…we need to do it manually.
Special thanks to Matti for helping me earlier.

Regards,
Kishor

Hi All,

Could you please share the steps you need to follow to compile the widget?
I am getting the following errors while trying to compile the widget set. I am using trial version of vaadin charts.

Is vaadin charts 4.0.0 compatible with Vaadin 7.5.6?

com.vaadin
vaadin-charts
4.0.0

How to resolve - Errors in ‘com/vaadin/addon/charts/shared/ChartConnector.java’
Line 163: Cannot refer to the non-final local variable seriesIndex defined in an enclosing scope.

This happens when trying to compile the widgetset.

Many Thanks,
Hema

Issue is resolved.

vaadin charts 3.x is compatible with vaadin 7.x
And charts 4.x with vaadin 8.x

changed the dependency in pom.xml to the below and issue is resolved.

com.vaadin.addon
vaadin-charts
3.2.0
