EclipseLink DBWS Service based on schema-formatted Results from custom SQL SELECT statements

This example shows an extension to an existing use case where the Web service exposes the results of executing some custom SQL SELECT statements; however, the 'shape' of the returned result is determined at design-time, not runtime.

Under normal circumstances, executing some custom SQL SELECT statement returns java.sql.ResultSet's from which one can determine the name and datatype of the columns of information. Since this information is not available until the SQL is executed at runtime, DBWS has a
