Problem deleting relations

SourceForge Submitter: javierpedrido .
I have two CMP 2.x entity beans that have a m:n
relationship (ModelEJB and NodeEJB) and a typical model
has thousands of nodes. The problems arrises when I
want to delete all the nodes related to a model, the
class
org.jboss.ejb.plugins.cmp.jdbc.JDBCDeleteRelationsCommand
creates a sql command so large that neither Oracle nor
MS SqlServer can handle it.
