Hello everybody!
I am having a problem in mapping document.
I don't know where I am doing wrong.
Its urgent! please help.
According to me each element in mapping file is correct, but even then invalid mapping exception is comming.
Question class have description(desc property), multiple answer options(many-to-many element), and one correct answer(many-to-one element).
Answer class have description(desc property), and long description(longDesc) property
