" Finders for CMP Beans
If you want to create additional finders, you have two options.
First, you can declare them in your home interface and then create
finder definitions in your JAWS deployment descriptor (see The JAWS Deployment
Descriptor). This is suitable for queries that only involve the table your
entity bean is stored in : effectively, you can write the WHERE clause
of a SQL query, but the FROM clause is fixed.
Second, you can implement the finders yourself, even if the rest of your bean uses CMP. This is best for complex queries that require other tables. Any time you implement a finder yourself (even for the default finders mentioned above), JAWS will use it rather than ignoring it. But you probably don't want to do that unless you really need to."
In fact, I wanted to have more information about this second option because it was exactly what I needed ...
Thanks again ...

to declare the WHERE and ORDER BY clauses of CMP finders. It sounds like
you want to use BMP and not CMP.regards,
