Spring didn't inject PatientDaoImp into your controller. Try this:

public class PatientController {

  @Autowired
  private PatientDaoImp dao;

Also make sure the following declaration is in your *-servlet.xml context file (not the main context file):

<context:component-scan base-package="com.pems.web"/>

In addition please add:

<context:annotation-config/>

to you *-servlet.xml file.
