Getting nullpointer exception when Annotation are used for Spring 3

[pol]

I have specified to scan all Entity and DAO classes in applicationContext.xml

<context:component-scan base-package="net.bapco" />

I strongly suggest a read of the reference guide (especially on what component-scan does and doesn't do) and rereading my post.

You haven't specified packages to scan on the LocalSessionFactoryBean

In short component-scan doesn't do anything for @Entities that is the responsiblitiy of the SessionFactory (and as such it needs to be configured).

Thanks for pointing that out. I have added the following

<bean id="SessionFactory"
		class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
		<property name="dataSource" ref="DataSource" />
		 <property name="annotatedClasses">	
		  <list>
           <value>net.test.model.Employees</value>
           </list>	
           </property>

and that problem got resolved. Now next issue is

SEVERE: org.hibernate.exception.GenericJDBCException: Missing IN or OUT parameter at index:: 1

I have resolved all my errors. Thanks a lot for your help and kindness. Very much appreciated.

I have one doubt though. If component-scan doesn't do anything for @Entities, then do we need to define all Entity classes in applicationContext.xml? Is this the best practice or are there better approaches to this?

Thanks again.
