<bean id ="employee" class="com.nihilent.Employee"   autowire="constructor" >  
 <constructor-arg index="0" value="22" />  
 <constructor-arg index="1" value="kaustubh" />   

That does not match any of the constructors you have defined for you employee object.

You need to either provide no arguments, an Address bean, or a String, int, Address
