Spring RESTful and Hibernate - spring

Question

I have a very simple database in postgres and i have used hibernate to "connect" to it. Everything works fine, i tested the database with hibernate and no problems so far.
Here is my DAO
#Repository("clientsBasicDao")
#Transactional
public class ClientsBasicDaoImpl implements ClientsBasicDao {
private Log log = LogFactory.getLog(ClientsBasicDaoImpl.class);
private SessionFactory sessionFactory;
private Session session;
public SessionFactory getSessionFactory() {
return sessionFactory;
}
#Resource(name="sessionFactory")
public void setSessionFactory(SessionFactory sessionFactory) {
this.sessionFactory = sessionFactory;
session = sessionFactory.openSession();
}
#SuppressWarnings("unchecked")
#Transactional(readOnly=true)
public List<ClientsBasic> findAllClients() throws HibernateException{
return session.createQuery("from ClientsBasic").list();
}
public ClientsBasic findClientById(int id) throws HibernateException {
return (ClientsBasic) session.
getNamedQuery("ClientsBasic.findById").setParameter("id", id).uniqueResult();
}
public ClientsBasic findClientByEmail(String email) throws HibernateException{
return (ClientsBasic) session.
getNamedQuery("ClientsBasic.findByEmail").setParameter("email", email).uniqueResult();
}
#SuppressWarnings("unchecked")
public List<ClientsBasic> findDirectClients() throws HibernateException{
return session.getNamedQuery("ClientsBasic.findDirectClients").list();
}
#SuppressWarnings("unchecked")
public List<ClientsBasic> findIndirectClients() throws HibernateException{
return session.getNamedQuery("ClientsBasic.findIndirectClients").list();
}
public ClientsBasic save(ClientsBasic client) throws HibernateException {
Transaction tx = null;
tx = session.beginTransaction();
session.saveOrUpdate(client);
tx.commit();
log.info("Client saved with id: " + client.getClientId());
return client;
}
public void delete(ClientsBasic client) throws HibernateException {
Transaction tx = null;
tx = session.beginTransaction();
Set<Resources> res = client.getClientResources();
if(res.size() > 0){ //there are client access resources for this client
Iterator<Resources> it = res.iterator();
while(it.hasNext()){
Resources resource = it.next();
resource.getClientsBasics().remove(client);
}
}
session.delete(client);
tx.commit();
log.info("Client deleted with id: " + client.getClientId());
}
}
Now, i am trying to learn restful web services so after some tutorials i tried my own implementation. It works, except when i try to use the method that connects to the database.
#RestController
public class GreetingController {
private static final String template = "Hello, %s!";
private final AtomicLong counter = new AtomicLong();
//http://localhost:8080/TestProject/greeting
// or
//http://localhost:8080/TestProject/greeting?name=stackoverflow
#RequestMapping("/greeting")
public #ResponseBody String greeting(
#RequestParam(value="name", required=false, defaultValue="World") String name) {
return new Greeting(counter.incrementAndGet(),
String.format(template, name)).toString();
}
//http://localhost:8080/TestProject/testing
#RequestMapping("/testing")
public #ResponseBody String home(){
return "Welcome, the server is now up and running!";
}
//http://localhost:8080/TestProject/client?id=1
#RequestMapping("/client")
public #ResponseBody String client( //FAILS HERE
#RequestParam(value="id", required=true) String id){
ClientServiceBackend cb = new ClientServiceBackend();
return cb.findClient(Integer.parseInt(id));
}
}
and here is the error
HTTP Status 500 - Handler processing failed; nested exception is java.lang.NoClassDefFoundError: org/hibernate/HibernateException

like i said, i am trying to learn rest and this is my 2nd week with spring, so this is all kinda new to me, but i would expect this to work since the database is working fine!
NOTE: I am deploying this on Tomcat v7
can someone please give a hand here?
Thank you :-)
EDIT:
I added the hibernate jar to the tomcat classpath, and now the error is
The matching wildcard is strict, but no declaration can be found for element 'tx:annotation-driven'.
