From the screenshot that you have attached , its quite clear that you are facing a ClassNotFoundException. Make sure that the class mybean/dbcon exists where is it supposed to be. Also you mentioned that you have copied your directory to the D:\apache-tomcat-6.0.37\webapps\ROOT\crs , why inside the ROOT ? it should be outside the ROOT folder.
