Hi,

I'm having problems using Hibernate to save a class of mine. I'm using Hibernate 1.2.5 (yeah, old, haven't seen a need to upgrade yet).

I won't paste the entire declaration but here's the gist:

Code:
public class Claim{

    // identifier
    private int claimId;

    // more stuff here.....

    public void setClaimId(int id){ claimId = id; }
    public int getClaimId(){ return claimId; }
    // more stuff here....
};


Mapping excerpt....


Code:

<hibernate-mapping>
    <class name="reuse.Claim" table="Claims.Claims" mutable="true">
   <id name="claimId" column="claimId" type="int">
       <generator class="native"/>
   </id>
........



So yeah, I noticed the problem and made a small servlet to test it:

Code:
public class TestServlet extends HttpServlet {
   public void doGet(HttpServletRequest request, HttpServletResponse response) throws IOException {
      Claim myClaim = new Claim();
      myClaim.setDescription("blah");
      
      Datastore ds = Hibernate.createDatastore();
      SessionFactory sf;
      Session session;
      try{
         ds.storeClass(reuse.Claim.class);
         sf = ds.buildSessionFactory();
         session = sf.openSession();
         
         session.save(myClaim);
         
      }
      catch (Exception e) {
         PrintWriter out = response.getWriter();
         e.printStackTrace(out);
      }
   }   
}


And here's what I get when I run it:

Someone else I now had similar problems and said it had something to do with the native identifiers returning a long.

Anyone know what I'm doing wrong? Am I not able to use ints as my identifiers? Thanks for any help

Did I not include enough information? Is there something else needed to answer my question? Did I stump everyone?

Can someone at least please confirm whether or not I can use integer identifiers?

Thanks for any help....

Old versions of Hibernate did not support int as an identifier type with native id generator.

But I am using hibernate-2.1

this is what I get:
Code:
22:06:16,352 ERROR [BasicPropertyAccessor] IllegalArgumentException in class: com.snap.businessobjects.network.Network, setter method of property: id
22:06:16,352 ERROR [BasicPropertyAccessor] expected type: int, actual value: java.lang.String


While:
Code:
<id name="id" type="integer" unsaved-value="null">
            <column name="NET_ID" sql-type="integer" not-null="true"/>
            <generator class="uuid.hex"/>
</id>


And the database is Integer (SQL Server 2000)

If you had read the documentation, you would have noticed that uuid.hex generates String:s, not int:s.
