[jBoss-User] why overide hashcode();

[Indika Fernando]

the hashcode() method is included in my PK class,
public int hashCode()
 {
        StringBuffer strBuff = new StringBuffer( );
        strBuff.append(userID);
        strBuff.append(listID);

  String str = strBuff.toString();
        int hashCode = str.hashCode( );
  return hashCode;
    }

When deploying using jboss it asks for a hashcode field ,I included it in
the Bean as well as in the deployment descriptor. I had to include a
hashcode field too in my table. Now my beans are working and I dont knpw why
this hashCode is needed in the table..The other problem is what should I
have for hashcode field when inserting records..
NEDD A QUICK REPLY
TIA.
