Code:

SQL> desc rkxx_xh;
Name Type       Nullable Default Comments 
---- ---------- -------- ------- -------- 
RKXH NUMBER(10)                           
JMZH CHAR(18)   Y 

Code:

            <id length="10" name="v_RKXH" type="java.lang.Integer" unsaved-value="any">
                 <column length="10" name="RKXH" not-null="true" sql-type="NUMBER(10)"/>
                 <generator class="sequence"> 
                        <param name="sequence">RKXX_XH_RKXH_SEQ</param> 
                 </generator>
            </id>

when i run the hibernate ,it tell me the error:
net.sf.hibernate.MappingException: could not instantiate id generator

but the sequence of oracle run ok!
SQL> select rkxx_xh_rkxh_seq.nextval from dual;

NEXTVAL
