I suggest following the recommendation of the documentation:

16.2.2.1. Rules/limitations for using stored procedures

You cannot use stored procedures with Hibernate unless you follow some procedure/function rules. If they do not follow those rules they are not usable with Hibernate. If you still want to use these procedures you have to execute them via session.connection() . The rules are different for each database, since database vendors have different stored procedure semantics/syntax.

Stored procedure queries cannot be paged with setFirstResult()/setMaxResults() .

The recommended call form is standard SQL92: { ? = call functionName(<parameters>) } { ? = call functionName(<parameters>) } or { ? = call procedureName(<parameters>} { ? = call procedureName(<parameters>} . Native call syntax is not supported.

For Oracle the following rules apply:

• A function must return a result set. The first parameter of a procedure must be an OUT that returns a result set. This is done by using a SYS_REFCURSOR type in Oracle 9 or 10. In Oracle you need to define a REF CURSOR type. See Oracle literature for further information.

For Sybase or MS SQL server the following rules apply:

• The procedure must return a result set. Note that since these servers can return multiple result sets and update counts, Hibernate will iterate the results and take the first result that is a result set as its return value. Everything else will be discarded.
• If you can enable SET NOCOUNT ON in your procedure it will probably be more efficient, but this is not a requirement.

Once your code will be aligned with the rules, if you still get an error, please provide the full error message.
