У меня проблема с моим API. Для одного из моих школьных проектов мне нужно было отправить свой проект в рабочую область Eclipse. Но я написал это на IntelliJ, потому что я предпочитаю. Когда я хочу передать свой код в Eclipse, проект не работает, поэтому я создал новый проект и поместил свой код внутрь. Но в данный момент я не могу получить доступ к этому API, потому что у меня есть исключение nullPointerException. NullPointerException на моем DAO и на IntelliJ это работает.
поэтому ошибка:
Servlet.service() for servlet access.RestApplication threw exception
java.lang.NullPointerException
at model.dao.DaoComment.getAll(DaoComment.java:150)

DAO выглядит так:
@Override
public List<User> getAll() {
CallableStatement stmt = null;
List<User> users = new ArrayList<>();
ResultSet resultSet = null;
try {
stmt = connect.prepareCall("{? = call USERPACKAGE.getAll}");
stmt.registerOutParameter(1, OracleTypes.CURSOR);
stmt.execute();
resultSet = (ResultSet) stmt.getObject(1);
if (resultSet != null) {
while (resultSet.next()) {
User u = new User();
u.setId(resultSet.getInt(1));
u.setEmail(resultSet.getString(2));
u.setPassword(resultSet.getString(3));
u.setFirstname(resultSet.getString(4));
u.setLastname(resultSet.getString(5));
u.setAddress(resultSet.getString(6));
u.setBirthday(resultSet.getTimestamp(7));
u.setRegisterDate(resultSet.getTimestamp(8));
u.setRelationship(resultSet.getInt(9) == 1);
u.setPhoneNumber(resultSet.getInt(10));
u.setGender(resultSet.getInt(11) == 1);
u.setInterestedIn(resultSet.getInt(12) == 1);
users.add(u);
}
}
} catch (SQLException e) {
e.printStackTrace();
return null;
} finally {
if (stmt != null) {
try {
stmt.close();
} catch (SQLException e) {
e.printStackTrace();
}
}
if (resultSet != null) {
try {
resultSet.close();
} catch (SQLException e) {
e.printStackTrace();
}
}
}
return users;
Обычно после этого я беру данные и отправляю их по json, но здесь это не работает.
