[akash-coded]

This is because of incorrect package naming. You have kept your SalaryAccount class in com.spring.driver.bean package. But in the configuration metadata XML file, you have provided the path as com.spring.Driver.beans.

The following bean definitions are the rectified ones:

      <bean id="SalaryAccount" class="com.spring.driver.bean.SalaryAccount" scope="prototype">
      	<constructor-arg index="0" value="201"></constructor-arg>
      	<constructor-arg index="1" value="rohit"></constructor-arg>
      	<constructor-arg index="2" value="20000"></constructor-arg>
      </bean>
      
      <bean id="SavingsAccount" class="com.spring.driver.bean.SavingsAccount" scope="prototype">
      	<constructor-arg index="0" value="101"></constructor-arg>
      	<constructor-arg index="1" value="sankalp"></constructor-arg>
      	<constructor-arg index="2" value="500000"></constructor-arg>
      </bean>
