Javax @NotNull annotation usage

Question

I have a simple method to get a list of documents for a given companyId. Here is the method:

@Override
public List getDocumentL         


        

Answer 1

If you @Inject a class with your method, its working as expected.

@Stateless
public class MyBean{ 
    @Inject
    TestClass test;
}

and

public class TestClass {
    public List getDocumentList(@NotNull Integer companyId)
    {
        //...
    }
}

ConstraintViolationException when you call your method with null parameter:

WFLYEJB0034: EJB Invocation failed on component MyBean for method ...:
javax.ejb.EJBException: javax.validation.ConstraintViolationException:
1 constraint violation(s) occurred during method validation.
