How to Enter the existing data in the entity beans?

Question

hello
my problem is as follows--
i am creating a CMP entity bean.in these beans client create the data instances using create() function.
now a entity bean will be created for the newly created data and it's EJBObject will also be formed.
now we will be able to perform finder methods over them.
remember these data has been newly created in the database.
but now if i want to perform the finder methods on the
existing data in the database( i don't need to use create() fn as i am not "creating" the data.). how will i perform the query over the existing data.
basically i have to make a CMP bean to extract the data corresponding to a particular condition , from the database table. i don't want to create the data in the database but just find out what data satisfies my condition.
thanking you
Prashant

All I say here is based on limited knowledge on 1.1 ejb specification. There could be improvements on 2.0 spec. 1.1 specification does not formaly provide how the finders should work for container managed beans. It leaves it at the hand of bean providers. Currently bean providers describes the finers in a description of the Entity Bean. Refer to documentation accompanied with application server you are using.
I attach the famous bank account example in weblogic server.
<finder-list>
<finder>
<method-name>findBigAccounts</method-name>
<method-params>
<method-param>double</method-param>
</method-params>
<finder-query><![CDATA[(> balance $0)]]></finder-query>
</finder>
</finder-list>
Method definition in Home inteface is
public Enumeration findBigAccounts(double balanceGreaterThan)
throws FinderException, RemoteException;
