Thanks for the reply Jaikiran. While using annotation I get the following exception during deployment,

My servlet code is as follows,





***public
**
 **class** StartupServlet **extends** HttpServlet{ 
*





@Resource(mappedName="java:jboss/datasources/weblogic.jdbc.jts.demopool")

**private** DataSource ds;
....
}

I am new to annotations and not sure what is wrong over here.

Thanks,
Abiya
