Hi
I'm trying to execute a sql server stored procedure via hibernate named query. However get the exception below when I do query.list(). Other sprocs are executed similarly and work just fine. THanks

I also tried this:

sql-query name="sprocName" callable="true">
<return-scalar column="newId" type="integer"/>
...


Returned a 1 as constant in the sproc.

and did a query.uniqueResult()

and now I get this

Unhandled exception
