Hi All,
I have created a simple test application which uses a stored procedure
to insert a record into a database using hibernate. I used hibernate
annotations and have overridden insert statement by
@SQLInsert(callable=true, sql="{? = call insert_party(?, ?, ?, ?)}",
check=ResultCheckStyle.PARAM)
However, hibernate throws the exception
...

extract row counts from CallableStatement

I studied JDBC3 specification whether PostgreSQL driver is wrong
or not and I think that the driver is correct. There is a conversion table
on page B-182 which should correspond to ResultSet object getter
methods only. There is nothing about the conversion being done
in CallableStatement's getter methods.
Attached is the patch agains hibernate core Branch_3_2 which fixes the
issue using
getBigDecimal(parameterPosition).intValue()
Please, could someone review the fix and apply the patch? Could you also
back port the fix? Thank you.

Julius Stroffek
