Dear all
i m using Hibernate 3.2.5.

i have got all mappings correct , i mean atleast it doesnt give me incorrect mapping error. I m facing problem with following exception
.
.
.
.
.
INFO: Default entity-mode: pojo
INFO: Named query checking : enabled
INFO: building session factory
INFO: Exception--->org.hibernate.MappingException: could not instantiate id generator
im a novice to hibernate
Please help me in correcting above Exception

Regards
Vikram

May be id value is not intialized. If you post mapping file and code then would be help for resolve this issue?

Dear Muru
Following is the xml which when added gives me the exception

<hibernate-mapping>
<class name="clientStock" table="clientstock_tbl">
<id name="productId" type="int" column="productId" >
<generator class="foreign"/>
</id>

<property name="reorderLevel">
<column name="reorderLevel"/>
</property>
<property name="quantity">
<column name="quantity"/>
</property>
</class>
</hibernate-mapping>

Vikram

Opt1:
Check your Database and foreign key value is assigned to not null or not.

Opt2:
If filed is not null checked then change the mapping file to <generator class="assigned"/>

Good Luck
