java.lang.ClassNotFoundException: com.microsoft.sqlserver.jdbc.SQLServerDriver
I got the above exception when i trying to deploying my Application
Since you're running a web app, you need to have the MS SQL Server driver--or the driver for any DB--stored in two places. Inside the app that becomes your WAR and then you need a second copy that is stored in the App Server's LIB directory. So, if you're running on Tomcat then you would put it /opt/tomcat/lib or C:\DEV\tomcat7\lib.
