Hibernate3 配weblogic出错！非普通高手来CharScanner; panic: ClassNotFoundException: org.hibernate.hql.ast.HqlToken

Question

hibernate.query.factory_class= org.hibernate.hql.classic.ClassicQueryTranslatorFactory
抛CharScanner; panic: ClassNotFoundException: org.hibernate.hql.ast.HqlToken        SessionImpl session = (SessionImpl)HibernateUtil.currentSession();
        Transaction tx = session.beginTransaction();
        session.delete("select c from Ecustomer as c where c.serialNo ="+serialNo);
        
String hqlUpdate = "update EaccountForm set customer_id =:customer_id ,customer_name = :customer_name where serial_no_ecustomer = :serial_no_ecustomer";
updatedEntities = session.createQuery( hqlUpdate )
                        .setString( "customer_id", customer_id )
                        .setString( "customer_name", customerName )
                        .setString( "serial_no_ecustomer", serial_no_ecustomer )                         .executeUpdate();        tx.commit();
        HibernateUtil.closeSession();     这个代码在tomcat里面没问题！但是移值到weblogic 就出这个问题！网上搜了半天居然没有解决！有遇见同样问题的哥们请回答！
