org.h2.Driver version for embedded mode - h2

Question

My requirement is H2 database should get started while deploying my war file in embedded mode. For that I created class(DbSetup) in my java project. I mentioned the same class in web.xml . Then I implemented contextInitialized(ServletContextEvent sce) method. In that method I am making connection to h2 db to which I made connection while deploying war. While getting war file, I am getting exception like " No suitable class found for jdbc:h2:~/test1. Could you please how to approach this problem? I am binding h2-1.4.192.jar with my war. I also copied the same jar to class path.
web.xml :
