Ok, no problem.
I kept fiddling, but still no luck. I noticed that when stepping through
the code, even with the @Table annotation, for some reason value for
"given" is null.
Anyway, here goes:
Entity
_______________________________________________
package net.leangen.expedition.openjpa.internal;
import javax.persistence.*;
@Entity
@Table( name="person" )
public final class Person
{
private static final long serialVersionUID = 1L;
private String sin;
private String name;
public Person(){}
public Person( String aSin, String aName )
{
sin = aSin;
name = aName;
}
@Id
public String getSin()
{
return sin;
}
public void setSin( String sin )
{
this.sin = sin;
}
@Basic
public String getName()
{
return name;
}
public void setName( String name )
{
this.name = name;
}
@Override
public String toString()
{
return getName();
}
@Override
public boolean equals( Object o )
{
if( this == o )
return true;
if( !( o instanceof Person ) )
return false;
final Person that = (Person)o;
return this.getSin().equals( that.getSin() );
}
@Override
public int hashCode()
{
return 17*getSin().hashCode();
}
}
