How to get a ResultSet using the resultClass attribute

[Guido García Bernardo]

Hello,

I would like to call an Oracle stored procedure that returns a REF
CURSOR for a given query, this way:

<procedure id="proc_cursor" parameterMap="query_map"
resultClass="java.sql.ResultSet">
   { ? = call web_utils.get_cursor( #query# ) }
</procedure>

I am having some problems with the resultClass, it seems like it doesn't
work...
Is it possible to use it with a ResultSet?   How could I retrieve a
ResultSet without changing the parameterMap?

Thank you very much,
Guido.
