So what is at this line

InsuranceHome.java:67

That is where the NPE is being thrown, so what is the instance that it is trying to call a method on. That instance var is null.

Hi Mano,

A NameNotFound exception is usually thrown when the name you have used to register your MySql datasource is not found in your app server directory service. Which app server are you using?
