Hi

I am trying for last few days to try the invient chart but am unsuccessful. And strange thing is that when I am surfing all previous communications in forum, no one seems to have the same problem I am facing. The class loader is not loading my ApplicationSevlet class. I am using Tomcat 7. I am getting the following problem

SEVERE: Servlet /InvientCharts threw load() exception
java.lang.ClassNotFoundException: com.invient.vaadin.InvientChartsDemoAppServlet
at org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1678)

and my build path is empty, ie it is not getting compiled into class files

I am running other vaadin programs in the same eclipse environment without problem, ie applicationServlet is running, but its extension fails,Can some one help me with the reason ?

Thanks

P.S.

I am able to remove the class loader problem, but now I am getting following error

INFO: Requested resource [VAADIN/widgetsets/com.example.invenientcharts.widgetset.InvenientchartsApplicationWidgetset/com.example.invenientcharts.widgetset.InvenientchartsApplicationWidgetset.nocache.js]
not found from filesystem or through class loader. Add widgetset and/or theme JAR to your classpath or add files to WebContent/VAADIN folder.

But when I checked, the widgetset has been compiled & the VAADIN/widgetsets/com.example.invenientcharts.widgetset.InvenientchartsApplicationWidgetset/com.example.invenientcharts.widgetset.InvenientchartsApplicationWidgetset.nocache.js exists in proper place.

As suggested by book of Vaadin, I recompiled widget set after deleting the old one, I have refreshed the project a number of times, clened tomcat working directory, clened the project & rebuilt it, but the same error persists.

I will be very thanful if any one suggests what I could do to remove the error
