Hi,
I’m having problems implementing the VisualizationsForVaadin addon.
I’ve added the addon JAR via Maven to my project, but it comes back with ‘class file has wrong version 50.0, should be 49.0’. I’ve tried re-compiling the addon, but had no luck. I’m using Java 1.5. Did anyone get this working in a 1.5 compiled application?
Thanks,
Jerry
I have managed to re-compile the addon with JDK1.5 and am no longer getting the above error message. However, the widgets don’t work.
I’m now getting the following error when loading the application:
I’m using the following versions (defined in Maven):
Vaadin 6.4.0
VisualizationsForVaadin 0.0.5
GWT Visualization 1.1.0
GWT User 2.0.4
When I try to package me application I get the following output:

Is there anything missing or can anyone see anything wrong with that output? I’ve looked into the VAADIN/widgetsets folder in the WAR file and I can see the “com.dme.gisadmin.widgetset.GISAdminAppWidgetset” folder there with a number of files inside.
Is there anything I might have missed? As far as I can tell the widgetset has been compiled and is available, so I’m not sure why I’m getting that message when I try to load the PieChart.

Any help would be great. 
Thanks,

I have managed to get it working by making sure that source files are also included in the JAR, not just classes.
Does anyone know whether it’s possible to add charts as components to a main window? I can only get this to work if I add a chart to it’s own subwindow.
Dear Jerry, could you elaborate a little further?
I am also trying to get VisualizationsForVaadin working but for now all i get is an empty ‘gwt’ folder in the target directory.
Which sources are you including, could you copy-paste the pom code snippet?
Thanks!
Hi Ivana,
I have created a Java project from the VisualizationsForVaadin.jar in Netbeans (just a simple Java project), and rebuilt it using Java 1.5. In build options there is a filter to ignore .java file which I have removed, and so when you build the project you end up with .class files as well as .java files in the JAR.
I have added that JAR to my local Maven repository, and referenced it in my pom.xml file of my web application. Please see my initial post with the dependencies included in my pom.xml.
When you run the ‘vaadin:update-widgetset’ target it should update your .gwt.xml file with a reference to the VaadinvisualizationApplicationWidgetset
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE module PUBLIC
"-//Google Inc.//DTD Google Web Toolkit 1.7.0//EN"
"http://google-web-toolkit.googlecode.com/svn/tags/1.7.0/distro-source/core/src/gwt-module.dtd">
<module>
<inherits name="com.vaadin.terminal.gwt.DefaultWidgetSet" />
<inherits name="org.vaadin.vaadinvisualizations.widgetset.VaadinvisualizationApplicationWidgetset" />
</module>
Then you can run the ‘package’ target and that should compile your widgetsets and add them to webapp/VAADIN/widgetset.
The only problem I have found with this addon is that when you load your app it doesn’t display. You need to resize the browser window to make sure the visualization is drawn.
