исключение нулевого указателя в org.hibernate.tuple.AbstractEntityTuplizer.createProxy

/ 12 марта 2010

Я использую Hibernate 3.2 с Struts 1.2 Framework вот подробности версий hibenate3.2, asm-2.2.3, cglib-2.1.3 Я получил это исключение при попытке загрузить объект

Я использую этот код для загрузки объекта 

public Currentprofile findById(java.lang.String id) {
    log.debug("getting Currentprofile instance with id: " + id);
    try {
        Currentprofile instance = (Currentprofile) getSession().get(
            "com.hibermappings.Currentprofile", id);
        return instance;
    } catch (RuntimeException re) {
        log.error("get failed", re);
        throw re;
    }
}

Мой файл hbm это 

<hibernate-mapping>
    <class name="com.hibermappings.Currentprofile" table="currentprofile" catalog="naukrionphone">
    <id name="jobseekerId" type="java.lang.String">
        <column name="jobseekerId" length="50" />

    </property>

    </property>
    <property name="designation" type="java.lang.String">
        <column name="designation" length="100" />
    </property>
    <property name="resumeTitle" type="java.lang.String">
        <column name="resumeTitle" length="500" />
    </property>
    <property name="profileDetails" type="java.lang.String">
        <column name="profileDetails" length="65535" />
    </property>
    <property name="requiredProfile" type="java.lang.String">
        <column name="requiredProfile" length="65535" />
    </property>
    <property name="activatedOn" type="java.util.Date">
        <column name="activatedOn" length="0" />
    </property>

    <set name="resumes" inverse="true" cascade="save-update">
        <key>
            <column name="jobseekerId" length="50" />
        </key>
        <one-to-many class="com.hibermappings.Resume" />
    </set>

</class>
</hibernate-mapping>

тот же код работает хорошо, когда я использую в простом Java-классе в методе main ..

Если это работает за пределами веб-приложения, убедитесь, что файл сопоставления правильно упакован и найден при создании SessionFactory при работе в контейнере.

Обновление: У вас неверная версия ASM в пути к классам (по крайней мере, не та, которую ожидает CGLIB). Какие версии Hibernate, ASM и CGLIB используют точно? Вы используете JAR, которые поставляются с Hibernate? Посмотрите, подходит ли вам решение, указанное в этой теме . Другой вариант - переключиться с CGLIB на Javassist.

Обновление: Вам нужен asm-1.5.3.jar с cglib-2.1.3.jar (или для замены обоих на cglib -nodep-2.1.3.jar , см. HHH-2222 ). Используйте JAR-файлы дистрибутива Hibernate.
