How to pass to Spring parameter by @Query, sql isn't working -

i'm using spring 4, postgresql , eclipselink.

i build query db, passing 2 parameters. i'm having these troubles :

call: select n.id, n.volume, n.numero numberentity n n.volume = :volume , n.numero = :numero query: readallquery(referenceclass=numberentity sql="select n.id, n.volume, n.numero numberentity n n.volume = :volume , n.numero = :numero")] root cause org.postgresql.util.psqlexception: errore: errore di sintassi o presso ":"   posizione: 70     @

and piece of code this:

    @query(value = "select n.id, n.volume, n.numero numberentity n n.volume = :volume , n.numero = :numero", nativequery = true) public list<numberentity> getbyvolumeandnumero(@param("volume") string volume, @param("numero") string numero); 

can me ? is correct pass parameter @query using ':' ? thank !
