The hashcode field is definitely not needed in the table. Do you have a
hashcode field in you Bean class?
Also, you may want to cache the hash value in your PK since your hashCode() is
pretty expensive. You are creating a StringBuffer, a String and using String's
hashCode() which is recomputed on every call!

Subject: [jBoss-User] why overide hashcode();
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.
