解决方法：
在hibernate.properties文件中增加属性：hibernate.query.factory_class，属性的值是org.hibernate.hql.classic.ClassicQueryTranslatorFactory. 如果用的是cfg.xml文件, 就在hibernate.cfg.xml中的<session-factory>下面添加一条声明: <property name="query.factory_class">org.hibernate.hql.classic.ClassicQueryTranslatorFactory</property>, 问题解决,但是如果程序中没用HQL语句，则不能删除，所以要改startWebLogic.cmd，修改startWebLogic.cmd，将set CLASSPATH=%WEBLOGIC_CLASSPATH%;%POINTBASE_CLASSPATH%;%JAVA_HOME%\jre\lib\rt.jar;%WL_HOME%\server\lib\webservices.jar;%CLASSPATH%
改为set CLASSPATH=%D:\wwwportalRun\WEB-INF\lib\antlr-2.7.5H3.jar;%WEBLOGIC_CLASSPATH%;%POINTBASE_CLASSPATH%;%JAVA_HOME%\jre\lib\rt.jar;%WL_HOME%\server\lib\webservices.jar;%CLASSPATH%
即可。
