a collection cmp and cmr field names

getRelationshipsForEjb

Collection getRelationshipsForEjb(String ejbName)

Gets a collection of names of cmr fields defined in this ejb jar for the specified ejb.

Parameters:

ejbName - the name of the ejb for which a list of cmr fields will be created

Returns:

the name mapper object

createUniqueNameMapper
