Junit-org.hibernate.AnnotationException引起的ExceptionInInitializerError

Question

I am getting this error when I try to run Junit for my class:

    ... 14 more

@OneToMany()
@LazyCollection(LazyCollectionOption.FALSE)
@JoinColumn(name="ID",referencedColumnName = "ID",insertable=false, updatable=false)
    private List<DataDetails> dataDetails;

Inside the setUp method, I just called initializer method. Which was not invoked. What should I do to run the test successfully?

Answer 1

You need to add pojo mapping in your cfg xml file.

<mapping class="xxx.yyy.zzz.bis.details.DataDetails" />

and make sure you specify appropriate qualified name of DataDetails in mapping. because your exception shows two different qualified names.
