Database: oracle9.
when I execute the following:

from mvc_hibernate2.provinces.Provinces as cat where cat.province_name='A'

it is ok.
But if I change 'A' to a Chinese character (for example: '王') or a Chinese string, it will complain as below:

org.hibernate.QueryException: expecting ''', found '¨a' [from mvc_hibernate2.provinces.Provinces as cat where cat.province_name='王']

at org.hibernate.hql.ast.QueryTranslatorImpl.compile(QueryTranslatorImpl.java:83)
at org.hibernate.impl.SessionFactoryImpl.getQuery(SessionFactoryImpl.java:414)

why?
eager for help...(Chinese hibernate forum has collapsed)
