Hi,

I am trying out hibernate but i am experiencing problems..

Also looked @ google for solutions but could'nt found a solution that worked for me.

Can someone give me a push in the right direction?
Would appreciate it..

Thanks in advance!

Here are the classes and mapping files:
Hengel.java
Code:
package Model;

/**

*/
public class Hengel  implements java.io.Serializable {


     private Integer code;
     private String merk;
     private Integer gevangenvissen;
     private Set<Vis> vises;

    public Hengel() {
    }

    public Hengel(String merk, Integer gevangenvissen, Set<Vis> vises) {
        vises = new HashSet<Vis>();
       
       this.merk = merk;
       this.gevangenvissen = gevangenvissen;
       this.vises = vises;
    }
   
    public Integer getCode() {
        return this.code;
    }
   
    public void setCode(Integer code) {
        this.code = code;
    }
    public String getMerk() {

        this.merk = merk;
    }

        this.gevangenvissen = gevangenvissen;
    }
    public Set<Vis> getVises() {
        return this.vises;
    }

        System.out.println(vises.size() );
        this.vises = vises;
    }

If I am not mistaken, bags are implemented as List, not Set. In Hengel.hbm.xml you have:

Code:
<bag name="vises">


but in Hengel.java:

Code:
public void setVises(Set<Vis> vises)

Oh my god, serious..

I changed vises to type List, then define it as arraylist..
that worked for me..
Damn:D thanks!!
