Maven and Tomcat

Hi,

I am building web application and I am using Vaadin charts. For test I insert data hardcode, but now I am using data from sql server. I am building web app on Apache Maven and deploying my app on Apache Tomcat. While I did not use sql server I did not have any problems. Now I get error “The origin server did not find a current representation for the target resource or is not willing to disclose that one exists.”.
