Nick, Your problem is the "type" set in your <id.../> tag. From (RTFM) the page: http://www.hibernate.org/hib_docs/reference/html/or-mapping.html#or-mapping- s1-4--generator
See the "identity" description, which reads: > identity - supports identity columns in DB2, MySQL, > MS SQL Server, Sybase and HypersonicSQL. The returned > identifier is of type long, short or int. The issue is your attempted use of class "java.lang.Long" instead of of "long", "short", or "int". I had a similar problem months ago when I started using Hibernate, until I re-read that primer. Also, you may wish to set your generator from "identity" to "native". That way, if you switch database products, it will automatically figure out if it can use identity, sequence, or hilo. (see the same document section just a few lines lower under the "native" explanation) Regards, David > <hibernate-mapping> > <class name="com.edhand.hibernate1.Item" table="item" > > <id name="id" column="id" type="java.lang.Long" unsaved-value="0"> > <generator class="identity"/> > </id> > <property name="name" column="name" type="java.lang.String" /> > <property name="description" column="description" > type="java.lang.String" /> > </class> > </hibernate-mapping> > -----Original Message----- From: Nick Heudecker [mailto:[EMAIL PROTECTED] Sent: Wednesday, April 07, 2004 11:42 PM To: Struts Users Mailing List Subject: Re: Struts and Hibernate The next thing I'll suggest is changing your mapping to: <id name="id" column="id" type="java.lang.Long" unsaved-value="null"> If that still doesn't work, your best bet is to hit the Hibernate forums: http://forum.hibernate.org/ > > <hibernate-mapping> > <class name="com.edhand.hibernate1.Item" table="item" > > <id name="id" column="id" type="java.lang.Long" unsaved-value="0"> > <generator class="identity"/> > </id> > <property name="name" column="name" type="java.lang.String" /> > <property name="description" column="description" > type="java.lang.String" /> > </class> > </hibernate-mapping> > > Tried both native and identity without succes. > > > -- > _________________ > Mario St-Gelais > www.gestionti.com > "Good judgment comes from > experience- usually experience > which was the result of poor judgment" > Bill Putnam -- Nick Heudecker System Mobile, Inc.
