SAP HANA DB connectivity through Spring JDBC Template

Hi,

I am able to connect SAP Hana database through JDBC successfully in standalone Java application and I am using ngdbc.jar, but when I try to do the same thing using Spring JdbcTemplate in my web-based project, I am getting following error. I am using BasicDataSource class of commons-dbcp2 i.e.

<bean id="dataSourceHana"

class="org.apache.commons.dbcp2.BasicDataSource" destroy-method="close">

</bean>

Also ngdbc.jar is on my application's classpath.

Also if try to use simple jdbc in Java web project , still I am getting the same ClassNotFoundException, it looks that in web-project somehow this com.sap.db.jdbc.Driver is not loaded.

Please anyone can guide me if there is anything that I am missing?

Error Stack trace:-

Cannot load JDBC driver class 'com.sap.db.jdbc.Driver'

java.lang.ClassNotFoundException: com.sap.db.jdbc.Driver
