JAXB проекта необходима помощь

Question

мне нужна помощь с этим вопросом в JAXB, в то время как я бегу проект, я всегда получил ошибку ниже

Property assignment is present but not specified in @XmlType.propOrder 
this problem is related to the following location: 
    at public int edu.asu.cse446.sample1.server.test.GradBook.getAssignment() 
    at edu.asu.cse446.sample1.server.test.GradBook 

Это мой код:

package edu.asu.cse446.sample1.server.test;

Answer 1

Хорошо. Вот почему они говорят - follow standard and conventions.

Проблема в том, что у вас есть имена переменных-членов, заглавные.

Измените их на что-то вроде - "id", "assignment", "midTerm", "quiz", "classLab", и он должен работать.
