spring injection issues with spring data

I am getting the following error Error creating bean with name
'genericRepository': FactoryBean threw exception on object creation;
nested exception is java.lang.IllegalArgumentException: Not an managed
type: class java.lang.Object
I am new to generics, if there are any generics issue please let me know
as well
my Contact.java is in com.merc.template.managelistofobjects.domain package
All other classes are in com.merc.template.managelistofobjects package

My main class contains the following code
ApplicationContext context = new
AnnotationConfigApplicationContext(MyApplicationContext.class);
CollectionManager collMgr =
context.getBean("contactCollectionManager",CollectionManager.class);
Contact contact = new Contact(2L,"xyz","abc");
collMgr.addToCollection(contact, true);
entitymanager.packages.to.scan=com.merc.template.managelistofobjects.domain
my spring xml file contains just one line
<jpa:repositories base-package="com.merc.template.managelistofobjects"/>
When i run the code I get the following error
java.lang.IllegalArgumentException: Not an managed type: class
java.lang.Object
