Query cannot be pushed down - error

Question

Hi,
I am using WSAD5 and Oracle10g and trying to generate RMIC
for a CMP entity bean. Using EJB QL I created a method:
findProductsByAge(int age) defined with:
select object(o) from Product o where o.productAge = ?1
The corresponding column AGE in the database is NUMBER(3).
On the Product bean the field productAge is Integer.
When I try to generate deploy code I get the error:
Query cannot be pushed down
I also defined a query findProductsByType(String type) with:
select object(o) from Product o where o.productType = ?1
and this one is working fine.
Can anyone help?
Thanks,
Igor

Dear All,
I have written a EJB QL for a CMP as
On trying to generate RMIC code for the same, I am
getting the following error message -
Error generating findByBasePrice(double) query
for bean ContainerManaged(Abstract schema
name=ProductTableSchema). Error=query cannot be
pushed down
The name of CMP bean is ContainerManaged. And,
the name of method is findByBasePrice(double).
The query is -
SELECT DISTINCT OBJECT(p) FROM ProductTableSchema
p WHERE p.basePrice = ?1
The XML tag for the aforementioned query is -
<query>
<description></description>
<query-method>
<method-name>findByBasePrice</method-name>
<method-params>
<method-param>double</method-param>
</method-params>
</query-method>
<ejb-ql>SELECT DISTINCT OBJECT(p) FROM
ProductTableSchema p WHERE p.basePrice = ?1</ejb-ql>
</query>Where am I going wrong?
Thanks in advance.
Regards,
Ashish A.Ashish, have you solved the problem? I am having the same problem but I use int instead of double as a parameter to the method. In the
database the corresponding column is of NUMBER(3) data type.
