org.hibernate.ejb.QueryImpl cannot be cast to com.exampl.standupmanager.domain.Employ

[hasan.iqbal.anik]

@RequestMapping(method = RequestMethod.POST, produces = "text/html")
public String create(@Valid Standup standup, BindingResult bindingResult, Model uiModel, HttpServletRequest httpServletRequest, Principal principal, Employee employee) {
if (bindingResult.hasErrors()) {

populateEditForm(uiModel, standup);
return "standups/create";
}

uiModel.asMap().clear();


String name = SecurityContextHolder.getContext().getAuthenticati on().getName();

Employee empByName = (Employee) Employee.findEmployeesByNameEquals(name);

System.out.println(empByName.getName());
standup.persist();
return "redirect:/standups/" + encodeUrlPathSegment(standup.getId().toString(), httpServletRequest);
}



that is the portion of my code. Everything works fine just except the line where I'm trying to create an employee by finding it by it's name. Employee is an active record class and the finder is default. I've just added it.

The error says:

org.hibernate.ejb.QueryImpl cannot be cast to com.example.standupmanager.domain.Employee

What am I doing wrong? Thanks in advance.

Employee empByName = (Employee) Employee.findEmployeesByNameEquals(name);

Finder returns a javax.persistence.TypedQuery<X> of your entity type, not the entity.
Get the result list or the single result:

List<Employee> empByName = Employee.findEmployeesByNameEquals(name).getResultList();

Employee empByName = Employee.findEmployeesByNameEquals(name).getSingleResult();

Regards !
