I think that the EJB 1.1 spec says that you have to implement these methods
in your primary key class, but don't quote me on that one. In any case,
this is what Weblogic is telling you. Below is the code I quickly generated
by the IDE that I use. It is for a table with a string and a date as the
primary key, but I'm sure you will get the idea:
import java.io.Serializable;
import java.sql.Timestamp;
public class LogEntryPK implements Serializable
{
public String username;
public Timestamp date_time;
public int hashCode() {
return (username.hashCode()+date_time.hashCode());
}
public boolean equals(Object that) {
if (!(that instanceof LogEntryPK))
return false;
LogEntryPK tmp = (LogEntryPK)that;
return (this.username.equals(tmp.username)
&& this.date_time.equals(tmp.date_time));
}
}
Just one other quick question - if custid is your primary key why do you
have findByPrimaryKey() and findByCustId() ?? Also if custid is your
primary key, findByCustId() should never return more than one bean so why
the Enumeration ??
Hope this helps !
