What if a have to search for the child records.
I have emplemented it by this way
I have created an ejbSelectChildRecords
<query>
<description>Find All childs</description>
<query-method>
<method-name>ejbSelectSolutiond</method-name>
<method-params/>
</query-method>
<ejb-ql>
<![CDATA[SELECT solutionds FROM SolutionBean s ]]>
</ejb-ql>
</query>
that return a Collection of remote object of the child records and I called
that ejbSelect from another method
