Java Gwt与hibernate

我需要与GWT（谷歌）一起使用hibernate和Springs

这是我的hibernate配置文件

<hibernate-configuration>
    <session-factory>
        <property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>
        <property name="hibernate.connection.url">jdbc:mysql://localhost:3306/test</property>
        <property name="hibernate.connection.username">root</property>

        <mapping class="com.AAA"  />

    </session-factory>
</hibernate-configuration>

这是我的主课

公共静态void main（字符串arg[]） {

这是一个不断出现的错误，尽管'Asm.jar文件的版本不同

如果我在动态web项目中使用这些JAR，一切都很好， 但在GWT Web应用程序中，它不是

请给出一些实现它的想法，

似乎是库问题，spring使用了什么版本？请参阅这看起来像是经典的拾取错误的jar错误。您是否尝试过Eclipse中的ctr-shft-t来查看哪个jar（s）此类是否驻留？您还可以使用JarScan在文件夹及其所有子文件夹中搜索类。您可能会在类路径中找到2个或更多asm jar。您使用spring orm.jar，hibernate-core.jarAm使用Springs-2.5.6。jar@GeorgyGobozovagain@swamy发生了相同的错误

    SessionFactory sessionFactory=new AnnotationConfiguration().configure().buildSessionFactory();
    Session hibernate_session = ((org.hibernate.SessionFactory) sessionFactory).openSession();
    hibernate_session.beginTransaction();

    System.out.println("Inside..");

    AAA pr = (AAA)hibernate_session.get(AAA.class,2);


    hibernate_session.getTransaction().commit();
    hibernate_session.close();

    System.out.println("Out sideee..");
}
